JOYO MOMIX-Pro Portable Audio Mixer with 48V Phantom Power and Dual OTG

For a phone-based live stream with vocals and guitar, the JOYO MOMIX-Pro brings two combo inputs, a stereo instrument input, and phone connectivity into one rechargeable mixer. Connect a microphone and instrument, shape the vocal or guitar sound with the built-in reverb, and monitor through headphones while sending stereo audio to a phone.

Its dual OTG ports also let you connect two phones at once, such as using one for streaming and the other for backing tracks.

Usage tips

Use CH1 and CH2 for microphones or instruments through their combo XLR/6.35mm inputs. If you use a condenser microphone, switch on 48V phantom power for the relevant channel. The dedicated stereo INST input accepts instruments such as keyboards and electronic drums, its signal stays dry, while the three-level reverb applies to CH1 and CH2. This setup gives a singer or solo performer a way to combine vocals, an instrument, and a stereo source in the same session.

For a simple streaming setup, connect a phone through OTG, plug in headphones for direct monitoring, and adjust the channel levels and reverb to suit the performance. With two phones connected, one can handle the stream while the other plays a backing track. The built-in rechargeable battery supports portable sessions, including outdoor streaming and street performance, without relying on a wall outlet during use.

What stands out

The MOMIX-Pro is more than a basic single-input phone adapter: its two combo channels and separate stereo instrument input allow up to three audio channels to be mixed together. Independent channel controls help balance voice and instrument, while the built-in reverb adds an effect to vocals or guitar without applying it to the dedicated stereo input. That makes it useful for recording a performance with a keyboard or electronic drums alongside a mic and another instrument.

For monitoring and output, it provides two independent headphone outputs, a DIRECT MONITOR switch for real-time headphone monitoring, and a MAIN OUT for connecting speakers or an external mixer. A VOCAL CANCEL switch reduces the original vocal in backing tracks for karaoke-style singing. Buyers also highlight the unit’s versatility, rechargeable operation, and range of inputs and outputs, with some noting its usefulness for practice.

Should you buy it?

Choose the MOMIX-Pro if your setup needs more than a direct microphone-to-phone connection. It brings instrument and vocal inputs, stereo accompaniment, channel-specific reverb, headphone monitoring, and dual-phone OTG streaming into a portable, battery-powered mixer. For a singer-guitarist, podcaster, or creator building a compact mobile recording or streaming setup, those connections make it practical to combine sources and monitor the mix in one place.
