A quick connection reality check: none of the five products in this roundup has Ethernet connectivity. They use USB, so none can serve as a direct network-audio interface for an Ethernet-based studio or stage rig. I’ve included them because they are the supplied options, but I rank them by how well they serve common recording and live-audio needs—and I call out where that differs from the title’s Ethernet requirement.

For a conventional computer-based recording setup, the Focusrite Scarlett Solo 4th Gen is my strongest all-round pick for its stated 120dB dynamic range and software bundle. The iConnectivity PlayAUDIO1U is the better match for managing multiple stage outputs and MIDI, while the M-AUDIO M-Track Duo offers two combo inputs and direct monitoring for straightforward recording. Those strengths do not make any of them Ethernet interfaces.
The main choice here is between USB recording convenience, input and output needs, and live-performance routing. If Ethernet audio is non-negotiable, skip this lineup and shop for a device that explicitly lists a network-audio protocol and Ethernet port. If USB is acceptable, the comparisons below can help narrow your choice.
Key Takeaways
- None of these five models lists an Ethernet port or network-audio protocol; each is a USB-connected alternative, not a true Ethernet audio interface.
- The iConnectivity PlayAUDIO1U is the most stage-focused option, with 12 outputs, MIDI connectivity, and a touchscreen, but it is heavier and more specialized than the desktop interfaces.
- The Scarlett Solo 4th Gen stands out for its stated 120dB dynamic range and software bundle, though its single-mic/single-instrument format limits simultaneous recording.
- The M-AUDIO M-Track Duo has two combo inputs and direct monitoring, making it a practical fit for two-source sessions without requiring Ethernet routing.

More Details on Our Top Picks
Focusrite Scarlett Solo 4th Gen USB-C Audio Interface
This is my leading choice for a compact USB recording desk, not for an Ethernet installation. The Scarlett Solo 4th Gen pairs a stated 120dB dynamic range with an Air mode intended to add presence to vocals and guitars. For a solo musician tracking one mic and one instrument, those features are more relevant than a large channel count: the unit is aimed at focused overdubbing rather than recording a whole group at once.
Compared with the Scarlett Solo 3rd Gen, this version’s clearest supplied distinction is its stated dynamic-range figure and newer generation, while both include a similar software bundle and compact USB-C format. The M-Track Duo may suit a buyer who wants two combo inputs for flexible source connections, but the Scarlett’s named Air feature and software offer give it a more defined singer-songwriter workflow. Neither one supplies Ethernet audio.
The input limit is the main compromise. A solo performer can record a vocal and instrument in a layered process, but this is not a good fit for tracking several microphones simultaneously. It also depends on a compatible computer and recording software. I’d rank it first for everyday USB home recording because its feature set is focused and its stated sound performance is strong; I would not buy it to connect audio over a network.
Pros:- Stated 120dB dynamic range for detailed recording.
- Air mode is designed to add presence to vocals and guitars.
- Includes several recording applications and plugins.
- Compact USB-C design suits a small recording setup.
Cons:- Limited inputs restrict simultaneous multi-mic recording.
- Requires a compatible computer and software setup.
- USB-C connectivity does not meet an Ethernet-audio requirement.
Best for: A singer-songwriter or solo musician who wants a compact USB-C interface, Air mode, and bundled recording tools.
Not ideal for: Anyone who needs Ethernet networking, multiple simultaneous microphone inputs, or a standalone live-routing device.
- Connectivity:USB-C
- Dynamic range:120dB
- Key feature:Air mode
- Included software:Pro Tools Intro+, Ableton Live Lite, Cubase LE, Hitmaker Expansion
- Product type:Compact USB audio interface
- Ethernet:Not listed
Our verdict“I’d choose the Scarlett Solo 4th Gen for focused USB recording, but not for networked audio.”
iConnectivity PlayAUDIO1U Audio/MIDI Interface
The PlayAUDIO1U has the clearest live-performance role in this group. Its 12 outputs and MIDI connectivity speak to playback rigs, virtual instruments, and stage setups that need more routing capacity than a basic singer-songwriter interface can offer. The OLED touchscreen and Auracle software also provide a more hands-on control path than the compact Scarlett models.
That output capacity distinguishes it from every other product here: the Scarlett Solo models and Synido are oriented toward small recording setups, while the M-Track Duo focuses on two input sources and straightforward monitoring. If a buyer needs multiple feeds for a stage system, the PlayAUDIO1U is the strongest fit in this lineup. But its listed connection is USB and XLR, not Ethernet, so it cannot be treated as a network-audio endpoint based on the supplied information.
Its specialization comes with practical costs. At 8.8 pounds, it is heavier than the portable desktop alternatives, and the absence of built-in effects means processing needs to come from other equipment or software. The supplied frequency-response field says 48000 hertz, while the maximum sample-rate field says 96kHz; I would confirm the precise specification with the manufacturer before relying on those figures for a technical design. Choose this for stage outputs and MIDI control, not a lightweight bedroom recording interface.
Pros:- 12 outputs support more complex live playback routing.
- Comprehensive MIDI connectivity suits virtual-instrument and stage-control setups.
- OLED touchscreen and Auracle software offer dedicated control.
- Designed with touring and live performance in mind.
Cons:- USB and XLR are listed, but Ethernet audio is not.
- The 8.8-pound weight makes it less convenient to carry than compact interfaces.
- No built-in effects or processing are specified.
- The supplied frequency-response and maximum-sample-rate details warrant clarification.
Best for: Performers and playback technicians who need numerous audio outputs and MIDI integration in a live rig.
Not ideal for: Ethernet-only systems, minimal desktop recording, Linux users, or anyone seeking a lightweight interface with built-in processing.
- Channels:12 outputs
- Maximum sample rate:96kHz
- Bit depth:24-bit
- Connectivity listed:USB, XLR
- MIDI:Comprehensive MIDI connectivity
- Control:OLED touchscreen
- Software:Auracle included
- Weight:8.8 pounds
- Ethernet:Not listed
Our verdict“I’d pick the PlayAUDIO1U for multi-output stage duties, provided USB connectivity fits the rig.”
M-AUDIO M-Track Duo USB Audio Interface
The M-Track Duo makes sense when two combo inputs matter more than extra software features. It accepts XLR, line, or instrument signals through two combo inputs, and its 48V phantom power supports condenser microphones. For a podcast with two microphones or a musician recording a vocal and instrument, that flexibility is more useful than the single-person layout of either Scarlett Solo.
Its USB/Direct switch is another practical distinction. Direct monitoring lets a performer hear the input without relying on the computer’s software monitoring path, which can help keep monitoring responsive during a session. Compared with the Synido, both offer two-channel recording and portability, but the M-Track Duo explicitly describes two combo inputs and stereo 1/4-inch outputs. The supplied details do not identify any Ethernet function, so this remains a USB sound-card-style option.
The tradeoff is a less fully documented feature set. The product description specifies 48kHz audio, monitoring connections, and Crystal Preamps, but no formal spec sheet was supplied for this roundup. Buyers who need exact dimensions, detailed converter data, or a stated software compatibility list should check those points before ordering. I’d place it ahead of the Solo models for two-source flexibility, but behind them for clearly stated headline recording specifications.
Pros:- Two combo inputs accept microphone, line, or instrument signals.
- 48V phantom power supports condenser microphones.
- USB/Direct switch provides a direct-monitoring option.
- Includes MPC Beats production software.
Cons:- Listed recording resolution is 48kHz, with no bit-depth figure supplied.
- No Ethernet connection or network-audio protocol is specified.
- Some technical details and dimensions are absent from the supplied information.
Best for: Podcasters and home musicians who need two combo inputs, phantom power, and direct monitoring over USB.
Not ideal for: Anyone needing Ethernet, extensive output routing, or a product with a fully supplied technical spec list.
- Connectivity:USB
- Audio resolution:48kHz
- Inputs:Two combo XLR/line/instrument inputs
- Phantom power:48V
- Headphone output:1/4-inch
- Main outputs:Stereo 1/4-inch
- Monitoring:USB/Direct switch
- Included software:MPC Beats
- Ethernet:Not listed
Our verdict“I’d choose the M-Track Duo when two flexible inputs and direct monitoring matter more than detailed specs.”
USB C Audio Interface for Recording Music, Streaming, Podcasting, Silver
The Synido is a small, portable two-input USB option for recording, streaming, and podcasting. Its stated 24-bit, 48kHz format and 48V phantom power cover common home-recording tasks, while three monitoring modes give users more than one way to manage what they hear. At 300g, it is the lightest clearly specified choice in this group, making it a sensible candidate for a compact travel kit.
Compared with the M-Track Duo, the Synido also targets two-channel work, but its listed connection is USB-C to USB-A and its description emphasizes three monitoring modes rather than a USB/Direct switch. The M-Track Duo gives a clearer account of its combo inputs and output connections; the Synido gives a stated bit depth and weight. Against the Scarlett Solo 4th Gen, it trades the Scarlett’s stated dynamic-range figure and software bundle for two-channel capacity and a compact form.
Compatibility is the caveat to weigh carefully. The product notes that a third-party driver may be needed for optimal compatibility, adding setup friction that the plug-and-record appeal of a small interface can’t erase. It also stops at two input channels and uses USB rather than Ethernet. I’d consider it for mobile USB recording when its driver support matches the computer, but not as a substitute for a networked stage interface.
Pros:- Compact 300g design is easy to carry.
- 24-bit/48kHz recording specification is clearly stated.
- Three monitoring modes offer flexible listening options.
- 48V phantom power supports condenser microphones.
Cons:- A third-party driver may be needed for best compatibility.
- Two input channels limit larger recording sessions.
- USB-C to USB-A connectivity does not provide Ethernet audio.
Best for: Mobile podcasters, streamers, and musicians who want a light two-input USB interface with multiple monitoring modes.
Not ideal for: Buyers who require Ethernet audio, broad driver compatibility without extra setup, or more than two input channels.
- Sampling rate:48kHz
- Bit depth:24-bit
- Inputs:XLR and 6.35mm
- Phantom power:48V
- Monitoring:Three monitoring modes
- Connectivity:USB-C to USB-A
- Weight:300g
- Dimensions:14 x 11.5 x 4.5 cm
- Ethernet:Not listed
Our verdict“I’d pick the Synido for portable two-channel USB work when its driver requirements suit the computer.”
Focusrite Scarlett Solo 3rd Gen USB-C Audio Interface
The Scarlett Solo 3rd Gen is a focused entry point for one microphone and one instrument. Its listed 24-bit/192kHz conversion, switchable Air mode, and gain halos are aimed at making vocal and guitar recording manageable without a large control surface. The included software tools add a starting set of recording and mixing resources, while the compact body suits a small home desk or mobile setup.
Compared with the Scarlett Solo 4th Gen, this model has a specific 24-bit/192kHz conversion figure in the supplied specs, while the newer model lists a 120dB dynamic range. The choice between them is not simply about one number: I’d favor the 4th Gen for its stated dynamic-range detail and current-generation positioning, and this 3rd Gen for buyers drawn to its listed conversion specification and straightforward solo workflow. The M-Track Duo is more flexible if two combo inputs are the priority.
One-mic-and-one-instrument capacity defines its ceiling. That arrangement works for layered singer-songwriter recording, but it cannot capture a multi-microphone session at once. A USB-C connection may also call for an adapter on some devices, and there is no Ethernet capability listed. I rank it below the 4th Gen because the newer model has a stronger stated differentiator in this comparison, but it remains a practical choice for a simple USB recording chain.
Pros:- Listed 24-bit/192kHz conversion specification.
- Switchable Air mode and gain halos simplify basic recording control.
- Includes multiple recording applications and plugins.
- Compact design and stated three-year warranty.
Cons:- Limited to one microphone input and one instrument input.
- USB-C may require an adapter for some devices.
- No Ethernet port or network-audio protocol is specified.
Best for: Singer-songwriters seeking a compact USB interface with one microphone input, one instrument input, and bundled software.
Not ideal for: Ethernet-based audio systems, multi-microphone recording, or buyers who need more than two inputs at once.
- Connectivity:USB-C
- Conversion:24-bit/192kHz
- Inputs:One microphone and one instrument
- Outputs:Two balanced outputs
- Key feature:Switchable Air mode
- Input control:Gain halos
- Included software:Pro Tools Intro+, Ableton Live Lite, Cubase LE, Hitmaker Expansion
- Warranty:Three years
- Ethernet:Not listed
Our verdict“I’d choose the Scarlett Solo 3rd Gen for simple singer-songwriter recording, not for expansion or Ethernet routing.”
How We Picked
I ranked these products against the stated Ethernet-audio intent first. The supplied descriptions identify USB or USB-C connections, and none names an Ethernet port or a network-audio standard. That mismatch is the biggest buying constraint, not a minor spec difference. I would not describe any of these models as suitable for an Ethernet-only installation.
Within that limitation, I compared the options by connection and use case, then by input/output capacity, monitoring, stated sound specifications, portability, and included workflow features. That approach puts the PlayAUDIO1U ahead for complex live output duties, while placing the Scarlett Solo 4th Gen first among the more general-purpose USB recording options. The M-Track Duo earns a separate role for its two combo inputs and direct-monitor switch.
I also treated missing or inconsistent details cautiously. For example, the PlayAUDIO1U description lists a 96kHz maximum sample rate while its frequency-response field says 48000 hertz; I report the supplied figures rather than infer a correction. The M-Track Duo has no formal spec list supplied, so its entry sticks to clearly stated product details. My ranking reflects the information provided, and a buyer who specifically needs Ethernet should use the buying guide to identify what to verify in a different product.

Factors to Consider When Choosing Ethernet Audio Interface
Start with the connection requirement. In this particular lineup, the word Ethernet does not match any listed connection. Each option is described as USB or USB-C connected, and the PlayAUDIO1U also lists XLR. That means these products can be compared as conventional computer interfaces, but none is documented as a network-audio interface. If Ethernet is mandatory, treat that as a reason to search beyond these five rather than hoping an adapter will add network-audio features.
Confirm that you need network audio, not just an Ethernet-shaped connector
A true Ethernet audio device needs more than a jack. Before buying for a networked studio or stage system, check the product documentation for the specific audio-over-network protocol it supports, compatible endpoints, channel capacity, and configuration software. A basic USB interface connected to a computer that happens to have Ethernet does not become an Ethernet audio interface. None of the supplied product descriptions identifies network audio, so buyers with that requirement should rule out this group.
Match inputs and outputs to the session
Input count affects what can be recorded at the same time. The Scarlett Solo models are aimed at a single microphone and instrument, while the Synido is described as a two-channel interface and the M-Track Duo has two combo inputs. Those designs work for overdubbing, a compact podcast setup, or a small number of sources. For a stage playback rig that needs many feeds, the PlayAUDIO1U’s 12 outputs make it the distinct option, though outputs are not the same as microphone inputs.
Choose monitoring for the way you perform
Direct monitoring helps when software monitoring adds delay. The M-Track Duo specifically lists a USB/Direct switch, and the Synido offers three monitoring modes. Those controls can matter to singers and instrumentalists who need to hear themselves while recording. The Scarlett descriptions emphasize Air mode and recording tools instead, while the PlayAUDIO1U’s touchscreen and software address live control. Compare the monitoring route you need rather than assuming every interface handles it the same way.
Read resolution figures in context
Sample rate and bit depth are only part of a recording setup. The Synido lists 24-bit/48kHz, the Scarlett Solo 3rd Gen lists 24-bit/192kHz, and the PlayAUDIO1U lists 24-bit with a maximum 96kHz sample rate. The M-Track Duo is described as 48kHz, without a supplied bit-depth figure. The Scarlett Solo 4th Gen instead highlights a 120dB dynamic-range figure. These specifications describe different aspects of performance, so I would compare the stated information without treating a larger sample-rate number as a complete measure of sound quality.
Check computer support, drivers, and portability
Compatibility can shape the real setup effort. The Synido notes that a third-party driver may be needed for optimal compatibility, and the PlayAUDIO1U description lists Windows and macOS support but not Linux. The Scarlett Solo 4th Gen also needs a compatible computer and software environment. For mobile work, the Synido’s stated 300g weight is a clear advantage over the 8.8-pound PlayAUDIO1U. Confirm the operating system, ports, power arrangement, and software needs before settling on a model.
Choose the right kind of workflow, not the largest feature list
These products serve different jobs. The PlayAUDIO1U is built around stage outputs and MIDI; the Scarlett Solo 4th Gen is the most clearly positioned compact recording choice; the M-Track Duo is a practical two-input option; the Synido prioritizes portability and monitoring choices; and the Scarlett Solo 3rd Gen keeps the setup focused on a singer-songwriter. Pick based on the actual sources, routing, and computer connection in your workflow. For Ethernet audio, none of those roles replaces a device with documented network capability.
Frequently Asked Questions
Is any interface in this roundup a true Ethernet audio interface?
No. The supplied descriptions list USB, USB-C, or USB and XLR connections, but none lists an Ethernet port or an audio-over-network protocol. I would treat all five as USB-based alternatives for recording or live performance, not as devices for direct Ethernet audio routing. If your setup requires network audio, choose a product whose manufacturer explicitly documents the protocol and supported network configuration.
Can I connect one of these USB interfaces to a computer that uses Ethernet?
A computer can use Ethernet for its network connection while a separate audio interface connects over USB, but that does not make the interface itself an Ethernet audio device. In this arrangement, the computer handles the network connection and the interface handles its USB audio connection. If you need audio to travel across the network between compatible devices, look for explicit network-audio support rather than relying on the computer’s Ethernet port.
Which option is the best fit for a live performance rig?
The iConnectivity PlayAUDIO1U is the strongest live-focused choice in this group because it lists 12 outputs, MIDI connectivity, an OLED touchscreen, and Auracle software. Those features make it a better match for backing tracks and virtual instruments than the compact Scarlett Solo models or two-input desktop interfaces. It remains a USB-connected option, weighs 8.8 pounds, and does not list built-in processing, so it will not meet an Ethernet-only stage design.
Which model should I choose for recording two sources at once?
The M-AUDIO M-Track Duo is a clear candidate because it lists two combo XLR/line/instrument inputs and 48V phantom power. The Synido is another two-channel choice with stated 24-bit/48kHz recording and three monitoring modes. The Scarlett Solo models are better understood as compact singer-songwriter interfaces with limited simultaneous input capacity. None of these options adds Ethernet connectivity, so the choice applies only if USB recording suits your setup.
What should I verify before buying an Ethernet audio interface instead?
Check that the device explicitly supports the network-audio protocol required by the rest of your system, not merely that it has a physical Ethernet connector. Confirm channel count, compatible software and hardware, operating-system support, power needs, configuration tools, and how the device integrates with your mixer or recording computer. I would also confirm that the product’s technical documentation matches the intended workflow, since a conventional USB interface and a network-audio endpoint solve different connection problems.
Conclusion
For a compact USB recording setup, I recommend the Scarlett Solo 4th Gen as the strongest general-purpose choice here, with its stated dynamic range, Air mode, and software bundle. Choose the PlayAUDIO1U if live playback outputs and MIDI are the priority; choose the M-Track Duo if two combo inputs and direct monitoring matter most; and consider the Synido for portable two-channel work when its driver requirements fit your computer. The Scarlett Solo 3rd Gen remains a straightforward option for a singer-songwriter who wants a focused USB setup.
If Ethernet audio is the requirement, I recommend none of these products. Their descriptions do not document Ethernet connectivity or a network-audio protocol. Shop for a purpose-built network-audio interface and verify compatibility with your existing system before choosing. That distinction matters more than any difference in sample rate, monitoring mode, or bundled software in this lineup.
