2 Channel Stereo Audio Mixer - Metal Shell, AUX Interface Support 2 In 1 Out Mini Stereo Sound Mixer Includes 1-Meter Audio Cables - For PC, Phone, Laptop, Headphones

This little mixer solved everything. I use it to connect two PC towers to the same speaker setup, and the difference is night and day—no more buzzing, ground loops, or weak signals. The audio is now crystal clear from both machines. It’s compact, well-built, and includes the cables you need to get started. I was so impressed, I bought another one to link two radio scanners to a powered speaker. Works like a charm. If you’re juggling multiple audio sources and want clean, reliable output, this device is a must-have.

Works perfect with my silent brass mute. Now I can play along with music on my phone and hear myself playing without wearing earbuds under my headset. If the music sounds crackly at all and you use Spotify, turn off the eq in settings.

WOW I wish I had known about this little gem sooner! I have my work laptop and home computer at my desk but with only one set of speakers. But, you can only use one input at a time, so I would have to connect/disconnect the second computer when I wanted to hear from it. Finally I decided that "this is crazy" and looked for a small mixer. This one works PERFECTLY for this need! Both computers are connected to it and the output goes to the speakers. No more connecting/disconnecting cables, the audio from both comes through! It's also very compact so it's easy to hide away. I also noticed no hum or ground noise too like I used to have when the laptop was plugged into it, so that's an added bonus. To power it I used an old USB cube that was too weak to charge modern phones quickly, but it powers this just fine. VERY happy with this product!

I was using a passive splitter and it was getting some feedback occasionally. This is much better, nice clear sound from both laptops simultaneously with no feedback. However, I took a star off because they were super cheap with the included cables. Obviously you need to connect this to speakers and two computers, but it only has enough cables to connect to speakers and one computer, I guess they're assuming you have the other cable, but i didn't. Also this needs to be powered, but they only included a USB option for that, so if you need to plug it into a real power outlet you'll have to buy a USB to AC adapter. They should have just included both of those things, as they're very cheap and most people would probably need them. But, other than the lack of included cables, it works great and I'm happy with it.

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.

I bought a new computer with integrated audio. I like to feed a line-in signal from a microphone preamp and sing along to tracks being played back on my computer. On this new computer, there was too much latency between what I was singing and what was heard on the computer's speakers. The usual solution is to buy an audio interface that has direct monitoring. I thought I'd try a simpler approach and use a Y-adapter to plug the line-in into both the computer and an input to a 2-channel stereo mixer. Then I could plug the line-out of the computer into the other mixer input and feed my speakers from the mixer out. All I needed is a basic mixer, hopefully USB powered for simplicity. The Cooidea looked like the perfect solution. The Cooidea 2-Channel Stereo Mixer arrived in a cardboard box along with instructions, a power cable and one aux audio cable. It appeared to be very solidly made and was very easy to install. I wired it according to my plan and turned off "Listen to this device" in my computer's settings for line-in. It worked perfectly, with zero latency. All I had to do is set the audio levels for line-in and media player for the correct vocal vs music balance.

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.

Really tidy device - very quiet use it to connect Guitar headphone/ effects unit and iPad to headphones. Perfect for this.

Perfekt in Qualität und Funktion. Sorgt für eine parallele Tonausgabe von zwei Synthesizern auf einen Aktivlautsprecher ohne Klangeinbußen. Stromversorgung über USB des Aktivlautsprechers.

商品は良いですが、使う際いつもの音量設定のまま音を鳴らすと大音量が流れるので小さめにしてから調整することをお勧めします。

Excellent small and efficient
