For most solo musicians and home recordists, I’d start with the Focusrite Scarlett Solo 4th Gen: it offers a focused, portable setup without asking you to power a separate supply. The Universal Audio Volt 2 Gen 2 is a stronger fit when you need two inputs, while the Focusrite Clarett+ 2Pre suits recording setups that need more connections and room to grow. These bus-powered interfaces trade standalone power for convenience, but differ in input count, monitoring features, portability, and how well they support multiple mics or instruments. I’ve compared the 15 options by their practical fit for bus-powered recording, not by headline specs alone. Read on for the full breakdown and help matching an interface to your setup.

Key Takeaways
The Scarlett Solo 4th Gen is the most balanced pick for one-person recording: the standard interface and bundle both center on a simple solo workflow, so choose the bundle only if the included XLR cable is useful to you.
Two-input models solve a different problem from solo interfaces: the Volt 2 Gen 2 and Clarett+ 2Pre are better starting points for recording two sources at once, while the Volt 1 and Scarlett Solo keep the setup more focused.
Generation and product names matter within the same family: the Scarlett Solo 3rd Gen is an older alternative to the 4th Gen, and Volt 1 and Volt 1 Gen 2 are distinct listings rather than interchangeable names.
Low-cost options vary most in workflow clarity: the M-Track Solo and Duo offer straightforward entry points, while less-established Piyone and generic interfaces list features such as loopback or echo control that buyers should verify against their actual recording needs.
Portable use is not one-size-fits-all: the compact Zoom AMS-22 and phone-oriented MAONO P2 address different mobile workflows, so device compatibility and power behavior should be checked before choosing either over a standard desktop interface.

More Details on Our Top Picks
Focusrite Scarlett Solo 4th Gen USB Audio Interface Bundle with XLR Cable
I’d choose the Scarlett Solo 4th Gen when one microphone or instrument is the whole recording setup. Its bus-powered USB connection keeps the rig compact, while Auto Gain and Clip Safe can help a solo creator set levels and avoid ruined takes without adding outboard gear. Air mode offers a tonal option for vocals, and the included XLR cable makes this bundle more ready to record than an interface-only purchase. Compared with the two-input PreSonus AudioBox 96, the Solo is the simpler fit for one source, but it gives up simultaneous two-mic recording and MIDI I/O. Its single-channel limitation is the main reason to skip it if interviews, duets, or stereo sources are part of the plan. A computer is also required; the supplied cables do not make it a standalone recorder.
Pros:- Bus-powered USB-C setup supports a compact recording rig.
- 24-bit/192 kHz recording supports high-resolution capture.
- Auto Gain, Clip Safe, and Air mode provide useful recording controls.
- Bundle includes an XLR cable and USB-C cable.
Cons:- Single-channel design cannot record two sources at once.
- Requires a compatible computer and does not include a microphone or speakers.
Best for: Solo singers, podcasters, and guitarists recording one microphone or instrument at a time on a Mac-compatible computer.
Not ideal for: Two-person podcasts, stereo recording, or musicians who need multiple simultaneous inputs or MIDI hardware connections.
- Channels:1
- Maximum sample rate:192 kHz
- Audio format:24-bit
- Connectivity:USB, XLR
- Compatible device:Personal computer
- Operating system listed:macOS
- Included accessory:XLR cable
- Power:Bus-powered USB
Our verdict“Choose the Scarlett Solo bundle for a straightforward one-source recording setup; pick the PreSonus AudioBox 96 if you need two mic inputs or MIDI.”
Universal Audio Volt 1 USB Audio Interface
The Universal Audio Volt 1 earns its place for creators who want to move between a computer and supported Apple mobile devices, while keeping a small interface at the center of the setup. Its vintage preamp mode gives vocals and instruments a character option that the more straightforward PreSonus AudioBox 96 does not emphasize, and the included software adds recording tools to the package. The listed two-channel configuration suits a solo source with stereo outputs, but it is not a two-microphone solution. Its 24-bit/192 kHz recording capability matches the Scarlett Solo bundle’s sample-rate ceiling, while the Volt’s broader device compatibility is the distinguishing advantage. The tradeoff is that an iPad setup may need an external power supply and adapter, so mobile compatibility does not always mean a cable-only rig. Its software bundle may also take extra setup for newcomers.
Pros:- Supports 24-bit/192 kHz recording.
- Vintage preamp mode adds a tonal option for vocals and instruments.
- Compatible with Mac, Windows, iPad, and iPhone.
- Includes recording software and plug-ins.
Cons:- One input does not support two-microphone recording.
- iPad use may require an external power supply and adapter.
- The software bundle can add setup complexity.
Best for: Songwriters and streamers who want one-source recording across a computer and compatible iPad or iPhone, with a vintage-style preamp option.
Not ideal for: Buyers seeking two simultaneous mic inputs, the simplest software setup, or a phone rig that runs without extra power accessories.
- Channels:2
- Maximum sample rate:192 kHz
- Audio format:24-bit
- Connectivity:USB
- Compatible devices:Personal computer, Mac, iPad, iPhone, microphone, electric guitar, MIDI devices
- Supported software:Ableton, Melodyne, Virtual Drummer, Marshall, Ampeg
- Dimensions:5.12 × 5.71 × 1.97 inches
- Weight:544 g
- Warranty:1 year manufacturer warranty
Our verdict“Pick the Volt 1 for cross-device flexibility and vintage preamp tone, but choose the AudioBox 96 if two mic preamps and MIDI matter more.”
PreSonus AudioBox 96 25th Anniversary USB Audio Interface
I’d favor the PreSonus AudioBox 96 when a bus-powered interface needs to handle two mic preamps and MIDI hardware without moving up to a larger studio hub. Its two Class-A mic preamps make it more practical than the single-input Scarlett Solo for interviews, duets, or recording a vocalist and an instrument at once. MIDI I/O also gives keyboard players a direct hardware connection, a capability not listed for either Volt 1 model. The compromise is a maximum rate of 24-bit/96 kHz, below the 192 kHz ceiling offered by the Volt 1 and Scarlett Solo. For many home-studio sessions, the two inputs and included software may matter more than that difference, but this is not the pick for someone seeking built-in DSP or onboard effects. Its USB-dependent setup can also call for extra accessories in some mobile configurations.
Pros:- Two Class-A mic preamps support simultaneous two-mic recording.
- MIDI I/O connects compatible hardware directly.
- Bus-powered, compact design suits mobile and desktop sessions.
- Includes professional recording software and supports common DAWs.
Cons:- Maximum sample rate is 96 kHz, lower than the 192 kHz options in this group.
- No built-in DSP or effects.
- Two-channel capacity limits larger recording setups.
Best for: Home-studio musicians, interview podcasters, and mobile creators who need two mic preamps plus MIDI I/O in a bus-powered interface.
Not ideal for: Buyers who need sample rates above 96 kHz, built-in DSP or effects, or more than two simultaneous channels.
- Channels:2
- Mic preamps:2 Class-A
- Maximum sample rate:96 kHz
- Audio format:24-bit
- Connectivity:USB
- MIDI:MIDI I/O
- Dimensions:5.5 × 5.5 × 1.75 inches
- Weight:2 pounds
- Supported software:Studio One Pro, Ableton Live, FL Studio, Cubase, Pro Tools, Logic Pro, Reaper
Our verdict“Choose the AudioBox 96 when two mic preamps and MIDI are more useful than 192 kHz capture or onboard processing.”
Universal Audio Volt 1 Gen 2 USB Audio Interface
The Volt 1 Gen 2 is a compact choice for someone who wants a bus-powered interface and a supplied software starting point, including UAD plug-ins and LUNA DAW. Its listed 32-bit/192 kHz capability and Hi-Z instrument input suit direct guitar or bass recording, while the Tone Shaping Preamp offers a way to shape a source without adding external hardware. Compared with the original Volt 1, this model’s stated 32-bit format and included LUNA software are its clearest points of distinction; the original listing highlights vintage preamp emulation and wider named device compatibility. Neither Volt 1 is a two-mic interface, despite the two-channel specification, so buyers should not mistake channel count for two mic inputs. This model also has a basic feature set and no external power option, which can limit more elaborate or power-sensitive rigs.
Pros:- Bus-powered USB design supports portable recording.
- Listed 32-bit/192 kHz recording capability.
- Hi-Z instrument input supports direct guitar and bass recording.
- Includes UAD plug-ins and LUNA DAW.
Cons:- Two-channel listing does not establish two mic preamps; the interface is positioned for simple recording.
- No external power supply option is listed.
- Basic feature set may not suit advanced routing needs.
Best for: Solo guitarists, vocalists, and home producers who want bus-powered recording with bundled UAD plug-ins and LUNA.
Not ideal for: Creators needing two mic inputs, advanced routing, or the option to use an external power supply.
- Channels:2
- Audio format:32-bit
- Maximum sample rate:192 kHz
- Connectivity:USB
- Audio input listed:USB
- Instrument input:Hi-Z
- Power:Bus-powered
- Weight:1.2 pounds
- Warranty:1 year
Our verdict“Choose the Volt 1 Gen 2 for a portable solo setup with bundled UAD software, but compare the original Volt 1 if its vintage preamp mode and stated device compatibility better fit your workflow.”
Focusrite Clarett+ 2Pre 10-In/4-Out USB-C Audio Interface
For a bus-powered interface that can anchor a larger recording setup, the Clarett+ 2Pre offers more room to grow than the Scarlett Solo, Volt 1, or AudioBox 96. Its 10 inputs and 4 outputs, two Clarett+ preamps, and ADAT expandability make it better suited to producers who may add channels or need more monitoring routes. Air technology and JFET instrument inputs also give vocal and instrument sources dedicated recording options. This is a different class of choice from the compact one-source Scarlett Solo bundle: the Clarett+ offers expansion and routing capacity, but takes up more space and weighs 4.1 pounds. It is bus-powered over USB-C, so buyers need a compatible port for power. MIDI I/O is absent, and the supplied data does not specify a maximum input level, which may matter to buyers planning around particular sources or gear.
Pros:- 10 inputs and 4 outputs provide more routing capacity than the smaller interfaces in this group.
- ADAT expandability supports adding inputs as a studio grows.
- Two Clarett+ preamps, Air technology, and JFET instrument inputs serve vocal and instrument recording.
- Bus-powered USB-C connection supports portable use.
Cons:- At 4.1 pounds, it is heavier than compact options such as the Volt 1.
- Requires a USB-C port for power.
- No built-in MIDI I/O is listed.
Best for: Producers and musicians building a portable studio who need multiple inputs and outputs now, with ADAT expansion for added channels later.
Not ideal for: Solo podcasters or beginners who need a small, simple interface, or users whose computer lacks a suitable USB-C port or who require built-in MIDI I/O.
- Inputs:10
- Outputs:4
- Connectivity:USB-C
- Maximum sample rate:192 kHz
- Preamps:2 Clarett+ preamps
- Expansion:ADAT
- Supported operating systems:Mac OS, Windows OS
- Weight:4.1 pounds
- Impedance:2.2 kΩ
Our verdict“Choose the Clarett+ 2Pre if you need a bus-powered interface with substantial I/O and ADAT expansion; for a single mic or instrument, the Scarlett Solo is simpler to carry and set up.”
M-AUDIO M-Track Duo USB Audio Interface
The M-Track Duo is a practical bus-powered choice when you need to record two microphones or instruments without a more elaborate studio setup. Its two combo inputs accept XLR, line, or instrument sources, and phantom power supports condenser microphones; zero-latency direct monitoring helps keep performance feedback immediate. Compared with the M-Track Solo, the Duo gives you a second input for two-person podcasts or stereo-capable sessions, while the Focusrite Scarlett Solo 4th Gen offers a higher stated sample rate and more polished recording extras. The tradeoff is a 48kHz ceiling, which is less suited to buyers prioritizing higher-resolution capture. MPC Beats and Ableton Live Lite add a useful starting point, though the software setup may take time. I’d choose it for straightforward, portable recording, not a feature-rich production rig.
Pros:- Two combo inputs accommodate microphones, line-level sources, and instruments.
- Phantom power supports condenser microphones.
- Direct monitoring with an adjustable mix supports low-latency tracking.
- Includes MPC Beats and Ableton Live Lite.
Cons:- Maximum audio resolution is 48kHz.
- The included software setup may feel involved for first-time users.
- A complete monitoring setup requires separate headphones or speakers.
Best for: Mobile musicians and two-person podcasters who need two mic, line, or instrument inputs and a simple USB-powered setup.
Not ideal for: Producers seeking sample rates above 48kHz, or buyers who want a more advanced feature set and higher-resolution recording.
- Inputs:2 combo XLR/line/instrument inputs
- Phantom power:Supported
- Maximum audio resolution:48kHz
- Main outputs:Stereo 1/4-inch
- Headphone output:1/4-inch
- Power:USB powered
- Supported software:Ableton Live Lite, MPC Beats, and compatible DAWs
- Operating systems:Windows 7–10, macOS High Sierra–Big Sur, iOS
Our verdict“Choose the M-Track Duo if you want two flexible inputs and useful bundled software in a portable bus-powered interface, and can work within 48kHz recording.”
Piyone Audio Interface, 2×2 24-bit/192kHz Studio Quality USB-C Recording Interface for PC/Mac/iOS
The Piyone 2×2 stands out on paper for buyers who want 24-bit/192kHz recording in a compact, bus-powered USB-C interface. Its two combo inputs cover microphones and instruments, with phantom power for condenser mics and Hi-Z support for guitar; zero-latency monitoring also suits tracking on a mobile or home setup. Compared with the M-Audio M-Track Duo, Piyone offers a much higher stated sample-rate ceiling, while the Duo includes named production software and supports a broader range of connection types in its specs. The Piyone’s plug-and-play approach may appeal to users who want less driver setup, but its two-channel design won’t accommodate a larger band or multi-mic session. The supplied information also gives fewer details about outputs and bundled recording tools, so I’d pick it for the resolution and USB-C simplicity rather than a fully specified studio package.
Pros:- Supports 24-bit recording at sample rates up to 192kHz.
- Two XLR/TRS combo inputs support microphone and instrument sources.
- Phantom power and Hi-Z support broaden input options.
- Plug-and-play USB-C connectivity and zero-latency monitoring suit mobile recording.
Cons:- Two channels limit larger recording sessions.
- Requires a compatible USB-C port for the intended connection.
- The supplied product information does not specify output connections or bundled software.
Best for: Solo musicians and home recordists with USB-C-equipped computers or iOS devices who want two inputs and a high stated sample-rate ceiling.
Not ideal for: Bands, multi-mic podcasters, or buyers who need more than two channels or clearly specified bundled software and output connections.
- Channels:2
- Maximum sample rate:192kHz
- Bit depth:24-bit
- Inputs:XLR/TRS combo
- Connectivity:USB-C
- Compatible devices:Guitar, PC, Mac, iOS
- Weight:1.63 lb
- Warranty:2 years
Our verdict“Pick the Piyone if two inputs and high-resolution USB-C recording matter more to you than a larger channel count or a clearly detailed software bundle.”
Focusrite Scarlett Solo 4th Gen USB-C Audio Interface
The Scarlett Solo 4th Gen is the strongest fit here for a singer-songwriter who records one microphone or instrument at a time and wants a polished, compact bus-powered setup. Its studio-grade converters, stated 120dB dynamic range, and Air mode give vocal and guitar recordings extra attention without adding a complicated input layout. Unlike the two-input M-Audio M-Track Duo or Piyone 2×2, the Scarlett listing specifies a single audio input, so it is less flexible for simultaneous two-source recording. It does offer up to 192kHz recording and a recording software and plugin bundle, making it a more production-oriented solo pick than the 48kHz Zoom AMS-22. Its compact footprint is useful for a desk or travel bag, but the limited input count and lack of MIDI make it a poor choice for expanding setups.
Pros:- Studio-grade converters with a stated 120dB dynamic range.
- Air mode is designed to add character to vocal and guitar recordings.
- Supports sample rates up to 192kHz.
- Includes recording software and plugins in a compact enclosure.
Cons:- The supplied specs list only one audio input, limiting simultaneous recording.
- No built-in MIDI or additional input options.
- Some devices may require an adapter for USB-C connectivity.
Best for: Solo vocalists, guitarists, and songwriters who prioritize recording quality, Air mode, and a compact interface over multiple simultaneous inputs.
Not ideal for: Two-person podcast teams, multi-mic sessions, or producers who need MIDI and several input options on the interface.
- Audio inputs:1
- Channels:2
- Maximum sample rate:192kHz
- Dynamic range:120dB
- Connectivity:USB-C
- Dimensions:3.78 × 5.63 × 1.83 in
- Weight:14.4 oz
- Operating systems:macOS, Windows, iOS
Our verdict“Choose the Scarlett Solo 4th Gen for a compact, higher-resolution solo recording setup, but select a two-input interface if you need to record multiple sources at once.”
USB Audio Interface with 48V Phantom Power, XLR/TRS Inputs, USB-C Recording Interface with Direct Monitor & Echo Control, 48kHz for PC, Mac, iOS, Guitar, Mic, Podcast
This interface’s clearest point of difference is its adjustable echo control, paired with direct monitoring and inputs aimed at microphones, instruments, and podcast setups. That combination may suit a streamer who wants monitoring effects close at hand rather than relying entirely on software. It also lists dual XLR/TRS combo inputs, a dedicated instrument input, and 48V phantom power, giving it a broader stated input mix than the solo-focused Focusrite Scarlett Solo 4th Gen. But the product data describes four channels while also giving only XLR and USB as audio-input types, so buyers should verify the actual routing before planning a multi-source session. Its 48kHz ceiling falls short of the 192kHz stated for the Piyone 2×2, and the three-month warranty is a notable limitation. I’d treat it as a feature-led streaming option, not a proven upgrade for high-resolution recording.
Pros:- 48V phantom power supports condenser microphones.
- Dual XLR/TRS combo inputs and a dedicated instrument input offer varied source connections.
- Direct monitoring and echo control target streaming and podcast workflows.
- Compatibility is listed for PC, macOS, and iOS.
Cons:- Maximum sample rate is 48kHz.
- The stated four-channel count is not clearly reconciled with the listed audio-input types.
- Warranty is limited to three months.
Best for: Budget-conscious streamers and podcasters who want direct monitoring, echo effects, and several listed input types in a USB-C setup.
Not ideal for: Recordists who need a long warranty, higher-resolution capture, or confirmed routing for a multi-input session.
- Connectivity:USB-C
- Listed channels:4
- Inputs:Dual XLR/TRS combo inputs and a dedicated instrument input
- Phantom power:48V
- Maximum sample rate:48kHz
- Monitoring features:Direct monitoring and echo control
- Compatible systems:PC, macOS, iOS
- Weight:1.5 lb
- Warranty:3 months
Our verdict“Consider this model if built-in echo control is central to your streaming workflow, but confirm the channel routing and accept its short warranty and 48kHz limit.”
Zoom AMS-22 USB Audio Interface for Recording & Streaming
The Zoom AMS-22 makes the most sense for a solo creator who needs a small, bus-powered interface that can handle a microphone or instrument alongside a stereo line source. Its XLR/TRS combo input includes Hi-Z, while loopback and direct monitoring support streaming as well as recording. A switch between studio and streaming modes gives it a more creator-focused workflow than the M-Audio M-Track Duo, which offers two combo inputs for conventional two-mic recording. That difference matters: the AMS-22’s stereo 3.5mm input is useful for routing another source, but it is not the same as having two full mic preamps. Like the M-Track Duo, it tops out at 48kHz, while the Scarlett Solo 4th Gen supports a higher stated sample rate. I’d favor Zoom for portability and loopback, not for expanded recording or high-resolution production.
Pros:- USB-C bus power supports portable recording and streaming.
- Combo XLR/TRS input includes Hi-Z for instruments.
- Stereo 3.5mm input accepts an additional line-level source.
- Loopback, direct monitoring, and studio/streaming modes support creator workflows.
Cons:- The single combo input does not suit multi-mic recording.
- Maximum sample rate is 48kHz.
- Its basic feature set may not meet advanced studio needs.
Best for: Solo streamers, podcasters, and mobile musicians who want USB-C bus power, loopback, and a stereo line input in a compact unit.
Not ideal for: Two-microphone podcasts, larger recording sessions, or producers who require sample rates above 48kHz and more advanced routing.
- Inputs:2
- Outputs:2
- Main input:XLR/TRS combo with Hi-Z
- Additional input:Stereo 3.5mm
- Maximum sample rate:48kHz
- Power:USB-C bus-powered
- Features:Loopback, direct monitoring, studio and streaming modes
- Weight:230g
- Operating systems:macOS, Windows, iOS, Android
Our verdict“Choose the AMS-22 for compact, bus-powered streaming with loopback and a stereo line input, but look to the M-Track Duo for two full combo inputs.”
Focusrite Scarlett Solo 3rd Gen USB-C Audio Interface
The Scarlett Solo 3rd Gen is a focused bus-powered pick for recording one vocalist or instrument at a time. Its Air mode can add presence to vocals and acoustic instruments, while the high-headroom instrument input is suited to direct guitar or bass recording. Compared with the M-Audio M-Track Solo, it offers a higher stated maximum sample rate and a more targeted tone-shaping feature; the M-Track instead lists specific RCA and headphone outputs and direct monitoring. The Scarlett’s 24-bit/192 kHz converters and bundled production software give new songwriters a ready starting point, but its two-channel design leaves little room for recording several microphones or a full band. It also depends on a Mac or PC and cannot operate as a standalone device.
Pros:- Bus-powered design avoids carrying a separate power supply
- Air mode offers a selectable presence boost for vocals and acoustic instruments
- High-headroom instrument input supports direct guitar and bass recording
- Includes music-production software to help new users get started
Cons:- Two-channel capacity is restrictive for multi-microphone sessions
- Requires a Mac or PC connection and has no standalone operation
- The included software choices may take time for beginners to sort through
Best for: Solo musicians recording vocals, acoustic guitar, or a direct electric instrument to a Mac or PC
Not ideal for: Bands and podcasters who need several simultaneous microphone inputs or standalone operation
- Connectivity:USB
- Channels:2
- Maximum sample rate:192 kHz
- Frequency response:20 kHz
- Dimensions:1.71 × 5.65 × 3.77 in
- Weight:12.32 oz
- Warranty:3 years
Our verdict“Choose the Scarlett Solo 3rd Gen for a portable, computer-powered setup centered on one singer-songwriter at a time.”
Universal Audio Volt 2 Gen 2 USB Audio Interface
The Volt 2 Gen 2 suits creators who want recording safeguards built into a compact bus-powered interface. Its auto-gain and clip protection are aimed at reducing level-setting mistakes, a useful contrast with the Scarlett Solo 3rd Gen, whose listed strengths center more on Air tone shaping and a single-instrument workflow. The Volt also has dual mic and instrument inputs, so two sources can be captured together without moving cables between takes. A full-color Smart Display provides an at-a-glance way to check levels, while the stated 32-bit/192 kHz capability and included UAD plug-ins and LUNA software broaden its appeal beyond a bare-bones interface. The tradeoff is still a two-channel ceiling, and its USB connection means mobile users may need a compatible host and setup rather than treating it as a self-contained recorder.
Pros:- Auto-gain and clip protection can help prevent common level-setting problems
- Two mic and instrument inputs support simultaneous two-source recording
- Full-color Smart Display makes status and level checks more accessible
- Includes UAD plug-ins and LUNA software
Cons:- Two-channel capacity will not cover larger ensembles or multi-mic sessions
- Requires a USB host, which can complicate mobile recording setups
- The supplied data lists a one-year warranty
Best for: Home-recording musicians and creators who want two inputs plus level-assistance features to reduce recording errors
Not ideal for: Multitrack bands or phone-first creators who need more inputs or a clearly documented standalone workflow
- Connectivity:USB
- Channels:2
- Maximum sample rate:192 kHz
- Bit depth:32-bit
- Inputs:Dual mic and instrument inputs
- Compatible systems:Mac, Windows, and iOS
- Warranty:1 year
Our verdict“Pick the Volt 2 Gen 2 if guided level control and two-source recording matter more than a larger input count.”
M-Audio M-Track Solo USB Audio Interface
The M-Track Solo is the straightforward choice here for basic USB-powered recording, especially when zero-latency direct monitoring and clearly specified output options matter more than high sample-rate figures. It offers one combo XLR/line input with phantom power plus a separate line/instrument input, which is enough for a host microphone and another source in a simple setup. Compared with the Focusrite Scarlett Solo 3rd Gen, it lists a lower 48 kHz resolution but spells out its stereo RCA and 1/8-inch headphone outputs, making its connection layout easier to judge for a modest podcast or streaming rig. Its lightweight format and software support keep setup practical. The limits are equally plain: it tops out at 48 kHz, has no external power option, and its listed operating-system support names older Windows and macOS versions.
Pros:- USB-powered design is convenient for portable recording
- Zero-latency monitoring supports comfortable tracking
- Combo input includes phantom power for condenser microphones
- Stereo RCA and 1/8-inch headphone outputs are specified
Cons:- 48 kHz resolution is below the 192 kHz options in this roundup
- No external power supply option is listed
- Specified Windows and macOS versions are older releases
Best for: Beginning podcasters, streamers, and musicians needing a simple two-input interface for a compatible computer
Not ideal for: Producers seeking 192 kHz recording, broader current-platform assurance, or a larger multitrack setup
- Audio resolution:48 kHz
- Inputs:1 combo XLR/line input with phantom power; 1 line/instrument input
- Outputs:Stereo RCA; 1/8-inch headphone
- Power:USB powered
- Compatibility:Windows 7–10, macOS High Sierra–Big Sur, iOS
- Included software:Ableton Live Lite, MPC, Pro Tools First, and more
Our verdict“Choose the M-Track Solo for uncomplicated, bus-powered podcasting or streaming when its 48 kHz ceiling fits your workflow.”
MAONO P2 Hybrid USB Audio Interface Dual XLR for PC, Phone, iPad, Guitar
The MAONO P2 earns its place by prioritizing device flexibility over a conventional computer-only studio setup. Its compatibility with PC, phone, and iPad, plus loopback and routing features, makes it a better fit for creators who move audio between a streaming device and recording software than the Scarlett Solo 3rd Gen, which is more centered on a straightforward computer-and-instrument workflow. The stated 24-bit/192 kHz recording and low-latency monitoring also leave room for home recording, while mute and routing controls support live production. However, the advanced routing may take time to learn, and the listed two-channel capacity does not suit multi-microphone panels. Buyers should also note that the supplied description does not specify a battery or power arrangement, so the bus-powered claim should be confirmed for the intended phone or tablet setup.
Pros:- Supports connections with PC, phone, and iPad
- Loopback, mute, and routing functions suit streaming workflows
- Lists 24-bit/192 kHz recording and low-latency monitoring
- Works with a broad range of recording and streaming software
Cons:- Advanced routing may be difficult for users seeking a simple plug-and-record setup
- Two-channel limit restricts multi-microphone recording
- Power requirements for phone and tablet use are not specified in the supplied data
Best for: Mobile streamers and podcasters switching between a computer, smartphone, or iPad and needing loopback or routing tools
Not ideal for: Panel podcasters needing several simultaneous mic channels or buyers who require confirmed bus-power details before choosing
- Connectivity:USB
- Channels:2
- Maximum sample rate:192 kHz
- Audio resolution:24-bit
- Compatible operating systems:Android, ChromeOS, Windows, iOS, macOS
- Supported software:Ableton Live, Studio One, Logic Pro, Cubase, GarageBand, FL Studio, OBS, and more
- Dimensions:6.42 × 8.27 × 3.23 in
- Weight:0.5 kg
Our verdict“Choose the MAONO P2 for a flexible streaming rig, but verify its power needs for your mobile device before buying.”
PIYONE 2X2 24-bit/192kHz USB-C Audio Interface for PC/Mac/iOS, XLR/TRS Combo Inputs, Monitor Loopback, Alloy Red
The PIYONE 2X2 is a compactly targeted option for creators who want USB-C connectivity, combo inputs, and direct monitoring in a basic two-channel interface. Its listed PC, Mac, and iOS compatibility gives it a mobile-friendly profile, while 48V phantom power supports compatible condenser microphones. Compared with the MAONO P2, the PIYONE lists a simpler feature set: it offers zero-latency monitoring and illuminated controls, rather than the P2’s advanced routing and loopback emphasis. That simplicity may suit straightforward tracking, but it also means fewer documented streaming tools. Both remain limited to two channels. The PIYONE’s supplied data does not list bundled software, so buyers planning a new studio setup may need to source a DAW separately; USB-C adapters may also be needed for devices without that port.
Pros:- USB-C connection and listed PC, Mac, and iOS compatibility
- XLR/TRS combo inputs handle microphone and line-level sources

How We Picked
I ranked these interfaces by how well they serve the central promise of a bus-powered setup: fewer cables, easy placement, and practical connection to a computer or supported mobile device. I compared input and output counts, monitoring options, controls, stated recording specifications, and whether the product’s design fits a clear use case such as solo vocals, two-source recording, streaming, or mobile work. I also considered how straightforward it is for a buyer to match the device to a real microphone-and-instrument setup.
The order favors useful capability and clear fit over the longest feature list. Established models with defined recording roles rank ahead when their functions are easier to judge; higher-input-count and premium options earn their place for buyers who need those capabilities, not because every home setup needs them. Lower-cost and lesser-known models remain in the roundup, but their listed features and compatibility claims make careful model-specific checking more important. Bus power alone does not confirm that a device will work with every phone, tablet, or high-draw accessory.
Factors to Consider When Choosing Buspowered Audio Interface
Before choosing an interface, I’d work backward from the recording session you actually plan to make. A portable unit can still be the wrong choice if it lacks the inputs, monitoring path, or device support you need. These factors help separate genuine convenience from specs that may not change your day-to-day setup.
Count Simultaneous Sources, Not Just Inputs
Think about how many sources you need to record at the same time, rather than how many instruments you own. A singer who records one vocal or guitar take at a time can often work comfortably with a solo interface; recording a vocal and guitar together calls for two suitable inputs. Also check what each input accepts, since a combo jack does not automatically mean every input has the same mic, line, or instrument behavior. Buying extra inputs can add flexibility, but it may also mean more controls and a larger device than a simple setup needs. If your recording plans may expand, prioritize usable simultaneous inputs over a large total-input number that includes playback or digital channels.
Treat Bus Power as a Connection Requirement
Bus-powered means the interface draws power through its connection to the host, which reduces cable clutter but ties operation to that host’s port and power delivery. A computer USB port may behave differently from a tablet connected through an adapter, hub, or phone accessory. Check the manufacturer’s compatibility and power guidance for your exact device, especially before planning outdoor or mobile recording. A hub can solve port shortages, but an unpowered hub may introduce dropouts or leave too little power for connected gear. If reliable operation matters more than a single-cable setup, keep a powered hub or another supported power arrangement in your plan.
Choose Monitoring Features Around Your Recording Routine
Direct monitoring lets you hear an input without relying entirely on the software’s processing path, which can make live performance feel more immediate. It is useful for tracking vocals or instruments, but it is not the same as software loopback for capturing computer audio during a stream. Echo controls and loopback labels can refer to different workflows, so check whether the feature routes a microphone, system audio, or both. Before buying, sketch how your microphone, headphones, speakers, and streaming or recording software will connect. A simpler interface may be easier to operate if you only need to hear a mic while recording, while a streaming setup may call for more explicit routing options.
Match the Interface to Your Mic and Headphones
Confirm that an interface supports the microphone type you own, including phantom power when required by a condenser mic. A dynamic microphone usually does not need phantom power, and some ribbon microphones call for extra care; check the mic maker’s guidance before switching it on. Headphone output level also matters: demanding headphones can sound quiet on a compact interface even when the recording signal is clean. Do not assume that a listed bit depth or sample rate guarantees a better result in your room, where mic placement and acoustic conditions often matter more. Spend first on the connection and monitoring behavior your gear needs, then treat headline resolution as a secondary choice.
Pay More for a Specific Expansion Need
A higher-tier interface makes sense when it solves a concrete limitation, such as needing more simultaneous inputs, more routing flexibility, or a particular recording workflow. It is less compelling if your sessions only use one microphone and you rarely change your setup. The Clarett+ 2Pre stands apart here as a more capable option for expanded recording, while a focused Scarlett Solo or entry-level M-Track can keep a basic rig smaller. Include the cost of microphones, cables, headphones, and any required adapters in your decision, since the interface is only one part of a working chain. Buying extra capacity can be sensible for a growing project, but choose capacity you can realistically use.
Verify Mobile and Bundle Details Before Ordering
Product names can conceal meaningful differences: generations, input layouts, included accessories, and mobile compatibility may change between listings. Compare the exact model number and manufacturer documentation rather than relying on a family name or a broad claim such as “for iOS.” A bundle can be convenient if it includes a cable you need, but it does not necessarily improve the interface itself. For phone-focused use, check whether the needed adapter is included and whether the phone can supply sufficient power during a session. This small check can prevent a portable recording plan from turning into a separate search for cables and power accessories.
Frequently Asked Questions
Can I use a bus-powered interface with an iPhone or iPad?
Sometimes, but the interface’s host compatibility and power needs determine whether the connection will work reliably. Check the manufacturer’s support information for your specific phone or tablet, operating system, and adapter setup. Some devices may need a powered USB hub or a separate power arrangement, which reduces the simplicity of bus power. Also confirm that your recording app recognizes the interface and its available inputs. If mobile recording is a central need, choose a model with clearly documented support rather than relying only on a broad product listing claim.
Is a two-input interface worth choosing if I usually record alone?
It is worth it if you sometimes record two sources together, such as vocals and guitar, or want to keep a microphone and instrument connected. Two inputs do not automatically offer identical connection types, so check how many can accept a microphone and whether an instrument input is available. If you always record one source at a time, a solo interface can be smaller and simpler to set up. The Volt 2 Gen 2 and Clarett+ 2Pre serve buyers with more simultaneous-source needs than the Scarlett Solo. Let your recording method, not a general desire for extra features, drive the choice.
Should I choose the Scarlett Solo 4th Gen or the Scarlett Solo 3rd Gen?
Start by comparing the exact features and included connections listed for each generation, then decide whether the older model covers your recording needs. The 4th Gen is the current-generation Solo option in this roundup, while the 3rd Gen may suit a buyer who wants its established one-person layout and does not need newer-generation changes. Do not assume that every accessory bundle includes the same cable or software. Check operating-system support and the details of the specific listing before choosing. If the interface will be a long-term part of a new setup, the newer generation is the more straightforward starting point.
Can a bus-powered interface record computer audio for streaming?
Not every interface with direct monitoring can capture audio playing on the computer. Direct monitoring is generally about hearing an input, while loopback routes computer playback into a recording or streaming application. Check the exact model documentation for supported loopback routing and confirm that your software can select it as an input. The Piyone listings and some streaming-focused products name loopback-related features, but buyers should verify how those routes work before building a broadcast setup around them. If you only need to stream a microphone, a more basic monitoring setup may be enough.
What should I check if my interface disconnects or runs out of power on a mobile setup?
First, test the interface directly with a supported cable and adapter, then check the host device’s power and compatibility guidance. A hub, long cable, or other connected USB device can affect available power or connection stability. Some microphones and accessories may also add demands that a phone or tablet cannot meet on its own. A powered hub or alternate supported power method may help, though it adds equipment to a setup chosen for portability. If the setup must work away from a desk, test the complete chain—including microphone, headphones, adapter, and recording app—before relying on it for a session.
Conclusion
For most solo home-recording setups, I’d choose the Focusrite Scarlett Solo 4th Gen as the best overall balance of focused operation and bus-powered convenience. The M-AUDIO M-Track Solo is my value pick for a straightforward entry setup, while beginners who want a familiar one-mic layout can start with the Scarlett Solo and add only the cable or accessories they actually need. For a more capable recording rig, the Focusrite Clarett+ 2Pre is the premium choice when additional inputs and flexibility justify the larger setup. Choose the Volt 2 Gen 2 if recording two sources at once is your priority, the Zoom AMS-22 for a compact recording-and-streaming workflow, or the MAONO P2 for phone-oriented use after checking device compatibility. Match the interface to your source count and host device first; the best bus-powered option is the one that works with your complete recording chain.
