Mini Stereo 4 Channel Line Mixer Headphone Monitoring Club Live Studio Recording

I wanted to listen to my own music while playing Gran Turismo 7 on the PS5 while using the PS5 3D audio headphones.I have a 3.5mm audio cable going from the controller to input 1 on the mixer.I have a 3.5mm audio cable going from my phone to input 4 on the mixer.I have a 3.5mm audio cable going from the mixer headphone monitor jack to the PS5 headphones.I have the mixer model with the additional USB power (important for this application).I turned off the music in the game and turned on my streaming music from my phone. It mixes right into the game sounds perfectly.The mixer is made of plastic but does not feel cheap. The sound has a little interference if my phone is too close to the mixer but that is easy to mitigate.If you don't mind 3 aux cables and 1 power cable around you while you play, this is a perfect device to listen to your own soundtrack while playing PS5 with the PS 3D headphones.

I'm using this mixer to coordinate four outputs across two computers into a single set of speakers (or headphones). My speakers have their own amplifier control, but with the headphones on I can rely on the in-built amplifier of the mixer. Except that it occasionally spits some interference/noise when under USB power. I've tried a few different power sources to combat this, but it seems to always happen. Maybe it's some other device causing interference, that the amp circuit it picking up, I don't know. But be aware that you might find yourself with some squelch in your headphones when using this under power. Otherwise, it does a great job of simple passive mixing.

I have it powered, and mixing several workstation PCs and a USB Bluetooth receiver. Seems to work pretty good, gets out of the way and stays out of the way.I found a tiny noise coming from somewhere, not sure where that came from. If it's this mixer, I'll update the review.

Works well. No issues with volume controls, and audio quality is usually great. The only real flaw is that it seems sensitive to outside RF. Whenever my cell phone or any other Wi-Fi or Bluetooth device is within a couple feet of the mixer I get constant crackling.

This review is for the "4 channel upgraded" version, which just means they repackaged the bare PCB version in plastic. It's basically a noise and Hiss generator. No Joke, but this thing sounds like a bad Joke.It sounds terrible. The hiss is ever-present and you can't "pot-down" to attenuate the effective noise this device creates throughout the range.With added power, no change. nor does the little switch do anything.Each time you plug in a 1/8" mini TRS the master volume decreases by 20% (at least).So you have 2+ lines-in the mix with volume reduced at 40%, PLUS the noise. great, how useless!Seriously, anyone in a crucial (for sound) audio situation should avoid the crap out of this thing. Just bloody awful.

Great Product! Great Low Price!Works Perfectly!

Low gain otherwise fine.

Needed a small mixer that could use or not use power so I could run a few small synths and drum machines that use 3.5mm trs cables .Can confirm that if your device already puts out a nice bit of gain then it’s possible to use this passively and have a small simple mixer without the need for power……Or you can power it also if needed .
