4 Port Audio Switch, 3.5mm Stereo AUX Selector, 4 Input 1 Output / 1 Input 4 Output Splitter, Switcher Box With 4 Channel Switch Knob, No External Power Required

Love this small 4-port 3.5mm switch! Works flawlessly! I had 3 audio devices I kept interchanging between manually using same ear-buds. This small switch handles it all (with one more port available for later!). Easy operation, and the volume control is a big-plus! If one audio device is louder than the other, can easily adjust the volume from the switch itself. No distortion and no 'scratchiness' sound when adjust volume.

I use 3 computers simultaneously and got tired of switching hdmi cables and the 3.5mm audio plug. I found hdmi switches that work great the only thing missing was a switch for the audio. This thing works perfectly. And it doesn't even require power. No audio quality issues whatsoever. Super easy to switch audio sources and even comes with a volume knob. There was no unpleasant sound while switching either. Couldn't be happier.

I regret buying this switch, I use it for work when I need to switch from my headphones to my speakers during multiple meetings. Well! It kind of does the job for meetings but the sound quality drops about 50% when I connect from PC to the switch. If you plan to listen to any music using this switch - forget about it, audio quality is horrible.

So far, this has been a decent audio switcher. Having the convenience of easily switching from headphones to speakers, etc. has been really nice compared to switching cords, especially with the way I have my office set up. My only complaint is that there is noticeable noise on the output at higher volumes. For my usage, I've been able to adjust things so that I don't have the switcher at high volume, but it's a small annoyance when I want to turn things up. Also, to be clear, it's possible that this device isn't the only source of noise. If I was certain this device was the only cause of noise, I'd rate it one star lower.

I bought this because my previous powered headphone monitor started getting static in the volume control knobs, making it difficult to adjust the volume to a comfortable level. This one is perfectly quiet. It doesn't have a built in amplifier, but that's one less thing to go wrong...I just turned up the volume on my computer. I use this to run my computer's audio out to desktop speakers, a pair of everyday headphones for YouTube videos, and a nice pair of headphones for mixing and critical listening. An advantage to this unit is you can't forget to turn down the speakers when you decide to use headphones instead...you have to switch from one to the other. NOTE: The input on the back of the unit can only be directed to one channel at a time via the switch. Or you can choose one of the 4 inputs (on the front of the unit) to go to the output channel on the back. So it isn't a mixer. It is a selector.

This works great and carries the audio well, letting me switch between two different sets of speakers and my headphones, and room for one more audio device. The only negative I have is the device has one input on the front, and all the other inputs on the back, which makes it a little awkward from a cable management perspective in some use cases. Nicely made, and a good value.

It was a game changer when I first got it, I've been using it pretty much non-stop since I installed it in my desktop setup. I used to switch between my speakers and two different sets of headphones. It has failed at some point in the last month. I just noticed it thinking my headphones were broken, but the left channel on the main input no longer works. I took it apart and cleaned it and there is no physical damage visible to the board, the switches, or the audio jacks. It worked well but didn't last long enough.

I work from home and also have a personal computer at the same desk. Without going into my entire set-up, I have several audio sources that I wanted to go to the same listening source (my case, ear buds). Switching sources is as easy as turning a knob. The volume control is also a nice feature. Also, was very surprised (in a good way) how small it is. It doesn't take up much real estate on my desk. Good product.
