1. Focusrite Scarlett 2i2 4th Gen
Buy Focusrite Scarlett 2i2 4th Gen on Amazon →
The Scarlett 2i2 has been the default choice for podcasters for a decade, and the 4th Gen doesn’t break that streak. It gives you two XLR/TRS combo inputs — enough to record host and guest on separate tracks — with 56dB of clean gain, which is sufficient for most dynamic mics including the SM7B without a cloud lifter. USB-C connectivity means one cable handles power and data on any modern laptop.
The new “Air” mode adds a subtle high-frequency presence boost that mimics transformer-based preamps; it’s worth toggling on if your voice sounds slightly dull on your recording. The loopback feature lets you capture computer audio alongside your mic signal, useful for remote interview workflows. Native drivers install without drama on Windows 11 and macOS Ventura/Sonoma.
Two practical limits: the headphone amp is okay but not loud enough to drive high-impedance headphones well, and the 2i2 doesn’t have MIDI I/O. Neither matters for podcast-only setups. If you pair this with an XLR mic, check out our best XLR microphones for podcasting guide for compatible pairings.
2. Focusrite Scarlett Solo 4th Gen

The Solo is the stripped-down sibling: one XLR input, one instrument input, same 4th Gen preamp quality. If you record alone and never need a second simultaneous mic channel, the Solo saves you real money over the 2i2 with no audio quality trade-off — you’re getting the same preamp circuit and converter specs.
The 4th Gen Solo also has the Air mode switch and USB-C. Gain tops out at 56dB, same as the 2i2. Direct monitoring is mono only, which is fine for podcasting since you’re not mixing stereo in your headphones during a recording. The instrument input on the front panel is a nice touch if you occasionally want to record acoustic guitar for intros.
Skip the Solo if you ever do in-person interviews or have a co-host who needs their own channel. For solo setups though, there’s no practical reason to pay for two inputs you won’t use.
3. SSL 2+
Solid State Logic built its reputation on studio consoles that cost as much as a house. The SSL 2+ brings that legacy preamp character to a $200 USB interface without inflating the price. The key feature for podcasters is the 4-output design: you get two headphone outputs with independent level controls, meaning host and guest can each monitor at their preferred volume without fighting over a single headphone knob.
The “Legacy 4K Mode” switch adds a harmonic character reminiscent of SSL’s classic 4000-series consoles. Subtle, but voices tend to sit slightly more forward in a mix when it’s engaged. Gain is rated at 62dB, which means the SSL 2+ can drive a Shure SM7B to usable levels without a preamp boost. MIDI in/out is included if you need it.
One trade-off: the SSL 2+ is larger and heavier than the Scarlett footprint, so it takes up more desk space. It also lacks the loopback function that the Scarlett line includes, which limits remote-recording workflows where you need to route computer audio back into the recording.
4. MOTU M2
The MOTU M2 punches well above its price on the metrics that actually affect sound quality: its ESS Sabre32 converters give it the lowest noise floor in this price bracket, and the built-in LCD meter bridge shows input levels at a glance without opening software. If you care about measurable specs, the M2 competes with interfaces in the $400–$600 range.
MOTU includes both a headphone output and a hardware loopback function. Two combo XLR/TRS inputs cover solo and co-host setups. USB-C connection, class-compliant (no driver install needed on Mac). The preamp gain reaches 53dB, so it will work with most dynamic mics — though high-gain mics like the SM7B or Rode PodMic Pro benefit from a clean boost like a Cloudlifter paired with the M2.
The trade-off is software: MOTU’s companion app is functional but bare compared to Focusrite’s Control mix software. Some users also report the front panel knobs feel plasticky relative to Focusrite’s rubberized feel. Neither affects recording quality.
5. Audient iD4 MKII
Buy Audient iD4 MKII on Amazon →
The iD4 MKII runs a single channel, and that channel features a genuine Class-A console preamp derived from Audient’s professional studio consoles — the same circuit topology used in desks that cost tens of thousands of dollars. The result is a preamp that’s measurably cleaner and warmer than the Scarlett Solo at similar price points.
Gain tops out at 58dB. The JFET instrument input on the front is high-quality enough for re-amping and DI recording. A scrolling LED meter keeps levels visible, and the big volume knob doubles as a scroll controller for DAW parameters via Audient’s iD app. USB-C, bus-powered, no drivers needed on Mac.
One real limit: it’s a single XLR input, so two-person recordings aren’t possible. The second channel is instrument/line only. Buy the iD4 MKII if you’re a solo host serious about preamp quality; choose the Scarlett 2i2 if you need a second mic input. If you’re still deciding on a mic to pair with either, our best USB microphones under $100 post covers entry points before moving to XLR.
6. PreSonus AudioBox USB 96
Buy PreSonus AudioBox USB 96 on Amazon →
The AudioBox USB 96 is the most straightforward interface on this list: plug it in, it works, no software required. Two XLR combo inputs, 48V phantom power, a headphone output, and a direct monitoring switch. PreSonus bundles it with Studio One Artist, a capable DAW that covers everything a podcast producer needs for editing and mixing.
Max gain is 50dB, which is modest. Dynamic mics with low output (SM7B, Rode PodMic) will need a gain booster or a hotter mic at this level. For podcasters using a condenser mic with phantom power — a common and practical choice — the gain ceiling is plenty. Build quality is sturdy with an all-metal chassis. It’s bus-powered over USB-A (not USB-C), so check your laptop’s port situation before ordering.
This is the right pick for first-time podcasters who want a no-drama setup bundled with recording software. For a compact monitoring solution to pair with any interface, our best noise-cancelling headphones for WFH roundup includes options that work well as podcast monitoring headphones.

FAQ
Do I need an audio interface if I already have a USB microphone?
No — a USB microphone has its own built-in audio interface. If you’re already happy with your USB mic’s sound quality, adding a separate interface adds cost and complexity without benefit. An audio interface becomes necessary when you want to use professional XLR microphones, need two simultaneous mic channels, or want more control over monitoring and routing.
What gain level do I need to drive an SM7B or Rode PodMic?
The Shure SM7B needs around 60dB of clean gain to hit a healthy recording level. The SSL 2+ (62dB) handles this without a booster. The Scarlett 2i2 4th Gen (56dB) gets close enough on most voices with the gain knob near maximum, though louder voices work better. If your preamp tops out below 55dB with a low-output dynamic mic, a Cloudlifter or inline preamp like the TritonAudio FetHead adds 20dB without coloring the signal.
What is loopback and do I need it for podcasting?
Loopback routes your computer’s audio output back through the interface as a recording input, letting you capture phone calls, video conference guests, or system audio on a separate track alongside your microphone. If you record remote interviews with Zoom, Riverside, or SquadCast, loopback is useful but not essential — those platforms record each participant locally in higher quality anyway. The Scarlett 2i2, MOTU M2, and Scarlett Solo all include loopback; the SSL 2+ and AudioBox USB 96 do not.
Is USB-C important in an audio interface?
USB-C matters mainly for cable compatibility and power delivery. All of the interfaces on this list that use USB-C are also class-compliant on modern operating systems, meaning no driver installation is needed on Mac. The PreSonus AudioBox USB 96 uses USB-A, which works fine — you’ll just need an adapter on a USB-C-only laptop.
Can I use these interfaces for video podcasting or streaming?
Yes. Any interface on this list appears as a standard audio input to video conferencing apps, OBS, and streaming software. The Scarlett 2i2’s loopback makes it especially convenient for streaming setups where you want to blend mic audio and music into a single stream. The SSL 2+‘s dual headphone outputs help in two-person video podcast setups where both hosts want IEM monitoring.
Bottom Line
The Focusrite Scarlett 2i2 4th Gen is the right call for most podcasters. Two clean inputs, loopback, USB-C, and a proven ecosystem of drivers and software make it the lowest-friction path to professional-quality podcast audio. Step down to the Solo if you record alone; step up to the SSL 2+ if you need dual headphone monitoring for an in-person co-host setup.
