Cooidea 2 Channel Stereo Mini Audio Mixer

This is such an awesome product, I've bought two of them. I was looking for a solution to be able to get audio from two computers (my work laptop and my personal PC) out of one set of speakers. KVMs can switch audio between the two devices, but can't mix from both devices at the same time. This product is a simple, inexpensive, high quality solution for the problem. This product allows me to hear audio from both devices simultaneously. I can hear a call coming in on my work laptop while listening to music streaming on my personal PC. This is exactly what I needed it for and it really comes through. This product has no volume, EQ, or power controls of its own. If it's plugged in it's working, and all such controls need to be handled on the devices it's mixing. I really like this as a feature. I don't need a bunch of extra controls sitting on my desk for this. The lack of controls allows me to tuck this away behind my desk, completely out of sight and out of mind. The existing controls on my devices can still be used just as before. Meanwhile, the audio from both devices "just works". I can hear both, just as if both devices were connected conventionally to the speakers. It's perfect. Don't let the price put you off. Just because it's not audiophile grade and just because it's inexpensive doesn't mean the audio coming from this won't be good quality. To my ear, it sounds more than good enough. I can't hear any degredation in quality as compared to plugging in the speakers directly. One thing I will note is that if you crank the speakers way up, you can hear some hissing. However, that often happens with many audio sources. That seems within the realm of normal and expected behavior, to me. Under normal listening conditions with everything set at a reasonable volume, I don't hear any hiss. The mixer's build quality seems very good. It has a metal housing and everything plugs in securely and nothing feels cheap. If there's one thing I can think of to complain about, it's the ridiculously bright blue power LED on the mixer. C'mon guys, what are we trying to prove here? I could read by this light. This is unnecessary, and obnoxious. A dim red LED would be fine. Thankfully, this stays tucked behind my desk so I can't actually see it most of the time. If I could though, I'd probably want to cover it with some electrical tape. If you're in the situation I described with two PCs and wanting to hear sound from both at the same time, look no further. This product will definitely meet your needs.

FANTASTIC! What a truly remarkable LITTLE TINY device! I use this as part of the IEM system in my professional DJ rig, and it’s nothing short of incredible. I needed a way to combine two completely separate audio sources into my wireless IEMs: the headphone/cue output from my Pioneer DJ controller and a separate monitor feed from my main mixer so I could hear my microphone. The Cooidea 2 Channel Mixer was the perfect solution. It allows me to independently control the level of both sources and hear exactly the mix I want in my IEMs, while still being able to cue songs normally on my DJ controller. It sounds great, adds no noticeable noise, requires no power, and takes up practically NO space in my rig. I honestly couldn't believe something this small and inexpensive could solve the problem so perfectly. If you have a situation where you need to combine and independently control two audio sources, this little mixer is absolutely worth trying. Five stars without hesitation. One of those rare little purchases that does exactly what you hoped it would do!

So this device is really freaking neat. I’ve been wanting to listen to music while playing games handheld on my switch, without bothering the wifey. Enter this device. You plug it into any USB A powered port, plug in the switch with the included AUX cable, plug in your music on the second port (in my case I used a Bluetooth amp connected to my phone). & lastly, insert your headphones into the port & away you go! It mixes the volume by the two inputs, so adjust volume independently on the devices connected. I would’ve liked to see a dial to adjust the mix level between the two channels, that would be neat. Another great idea would be a small battery to give it just a few hours of go time between charges. Great value purchase, slightly jank setup. My only complaint is the static background noise if there’s no sound in either channel.

This “Cooidea 2 Channel Audio Mixer” is good purchase, if you want to share a powered speaker system between two computers. I have a nice powered HiFi computer speaker system, which I am currently using with a new Windows 11 computer. I also have an older mini PC, which I want to continue using, so I bought a KVM keyboard & monitor switch, so I could use both the new PC, and the old mini computer. The KVM / HDMI switch does not include the capability to switch the stereo audio inputs to the powered speaker system, so I tried using a separate stereo audio switch, but this solution resulted in “ground loop noise”, and also 60 Hz noise from the speakers, when the old computer was switched OFF. Also, this audio switch setup was kind of a pain, because I had to change two switches, each time I wanted to switch from the new computer to the old one. I discovered that the easy remedy to this problem was this “Cooidea Audio Mixer”. All that I had to do was plug the audio outputs from each of the computers into the two mixer inputs, and connect my powered speakers to the output of the audio mixer. I powered the mixer with a 5 volt USB power adapter from an old cell phone. Using the mixer eliminated the ground loop noise problems too. The sound quality from both computers is now flawless. Since I never listen to sound from both computers at the same time, I no longer need an audio switch. This mixer is a great solution, for my two computer speaker setup!

Regardless of what outlet I plug this into, with there being a power surge strip, when my lights are on I get a buzzing noise. Other than that it does do exactly what it claims to do, at a low cost. In the dark, primarily.

Works for my situation, but I notice that there is static noise coming from the speakers even when the connected input devices are turned off. I believe this can be mitigated using high quality shielding or maybe some internal components are cheaper, but then again, this mixer was very affordable.

Bought this with a specific use in mind...and it worked! I have a decent sound system in living room that the TV plays through but I also wanted the Amazon Echo to play through it as I use that to listen to music when working around the house. The Echo is okay on sound but I wanted it on the big system to really jam out. So I went looking and found this little thing. Well I bought it and hooked it all up and BOOM! I have sound from the TV as I normally did and now I have some sound from the Echo to jam out to. There is no volume control for the device itself as your using the volume of the device you are plugging into it. This device is just actually combining two sources into one output with no onboard controls. This also worked in my favor as there is nothing for anyone to mess up. It has such a small footprint design it was really easy to install it and tuck it behind everything. Did exactly what I needed it to do.

Worked fantastic for the first month. Then one day I went to listen to some music and nothing! It was completely dead. The return window just closed so now I'm out 25 dollars. Before it broke, the audio quality was good, it was small and portable and appeared to be well designed and constructed. Was worth the price until it failed.

I've found this is perfect for playing and practising guitar through headphones along with audio from a PC, without taking the audio interface from my main music setup. Just run the output from any guitar headphones amp and you're up and running. The unit is very small and well made, and the sound quality is excellent - certainly more than good enough for my purposes. I wish I'd got something like this years ago.

A perfect 2 Channel Powered Stereo Audio Mixer. small but efficient. It works well for me practicing on my digital piano and listening to my lessons on my laptop. The laptop input has a low ground loop noise , a low level noise, hardly perceptible.

I have 2 computers and one set of speakers. This solves the problem perfectly. Small, simple to install, sound quality un- affected, and I don't need to manually switch between computers.
