OneOdio solocaster review: an impressive and affordable all-in-one audio interface

OneOdie is best-known as a headphone manufacturer, producing options at a range of price points for DJs, gamers, and studio monitoring. But with the OneOdio solocaster, the Chinese audio company has created an all-in-one audio interface and podcast console aimed at streamers, podcasters and content creators.

The idea behind the solocaster is to provide users with the ability to capture professional-sounding audio with a simple and easy-to-use hardware interface. This snazzy little unit is fairly compact, so it doesn’t take up much desk space.

The device combines a sound card, voice transformer and mixer in a single compact unit, supporting multi-source input mixing and loopback audio for recording PC audio alongside your microphone. It has pretty much everything you could need for recording audio, not to mention it has a few neat little tricks up its sleeve.

It includes four FX pads, three fader controls, and six built-in voice effects for real-time vocal manipulation. A live noise filter and auto-ducking keep your voice clear over background sound, while 11 RGB lighting modes look great.

OneOdio solocaster: Price

The OneOdio solocaster was launched on February 3 2026, and was immediately available on the OneOdio Website and Amazon in the US and UK. The device costs just $49.99 / £49.99, which is a fantastic price considering all of the features.

Just to put this into perspective, I own a Behringer U-Phoria UM2 for use as an external soundcard I can plug XLR mics into for sound recording, and this costs just over half as much. The thing is, the Behringer is incredibly basic in comparison, with only the most basic features available.

This makes the solocaster a much better option in my opinion, but only if you do need features beyond an external soundcard/audio interface.

OneOdio solocaster: Design & Handling

The Solocast is well made, but there’s no getting away from the fact that it’s plasticky and lightweight. For a device where you’re turning knobs, hitting buttons and moving mixer sliders, a little weight beyond 12.03oz / 350g would make it feel more solid. However, the four wide rubber feet on the bottom do successfully keep the solocaster in place.

It’s also a pleasingly compact device at 6.7x5.4x1.5in (2.1 inches with knobs) / 17.0x13.8x3.7cm (5.4cm with the knobs), so it doesn’t take up too much desk space.

On top of the solocaster is where all the controls are, and these include illuminated buttons offering various functions, including four FX pads that can record for up to 30 seconds, so you can use them to apply a wide range of sound effects, voice or even music.

The buttons are a good size for use, while the knobs and sliders provide further sound control. The latter are smooth in operation, and although the buttons do work well, they do make a slight clicking noise when pressed, despite being made of rubber.

These and the knobs feature integrated LED strips with 11 dynamic RGB lighting modes, including solid colours, gradients and animated rainbow effects. The latter does look great to be fair, even if they’re ultimately pointless.

Connectivity is reasonably good but could be even better. The solocaster supports five independent audio channels across USB-C, 3.5mm, XLR, Bluetooth and AUX, making it a true all-in-one hub for managing microphones, system audio, background music and external sources simultaneously. What I would have liked to have seen would be two XLR inputs to allow for two microphones to be used for podcasting.

OneOdio solocaster: Performance

In all honesty, the OneOdio Solocaster does everything it claims to and does it well. The sound quality is great, and once you’ve had a little play for a few minutes, everything is incredibly easy to use. There are no drivers to install either – it's plug-and-play.

Sound mixing is handled through three dedicated faders for real-time level adjustment, although one is for the headphones, so it’s not going to affect the recorded sound. It’s probably fairer to say there are two sliders for sound mixing.

At the heart of the OneOdio Solocaster is a professional-grade preamp with 48V phantom power. This allows you to use professional XLR microphones and deliver broadcast-standard sound with just this simple soundcard doing all the work for you.

Live noise filtering and auto ducking keep voices clean during gameplay or commentary, with background noise reduction, while direct monitoring and one-touch mute give creators additional control and confidence during live and recorded sessions. Live monitoring is an essential feature and one that all similar sound cards offer.

There are six real-time voice modulation modes – female, male, child, elder, creature and robotic. I’m not sure that they’re successful in terms of matching the voice types since they all sound like creatures of some kind, but they work exceptionally well and inject a little fun into the recording when required.

Then four programmable FX pads allow custom sound clips, audio tags or effects to be triggered instantly. These also work well, and I played around using the voice modulations to record phrases that could be played back at the press of a button. You can also connect your phone via Bluetooth to add music or use the line-in to play music from your computer.

OneOdio solocaster: Verdict

The OneOdio solocaster is a highly capable audio interface that offers many more features than you’d expect at the price point. Audio quality is good, and even the voice modulations work exceptionally well despite not necessarily being true to their descriptions, while the FX buttons worked exceptionally well.

The clue is in the name, but my main issue with the solocaster is that it only has one XLR input. Two would be useful, so two microphones could be used at once when podcasting. The headphone slider on the device could have been used instead for the second mic.
