3.5mm Stereo Audio Switcher（1 in 2 Out /2 in 1 Out） with 3.5mm Audio Cable, 2 Ports AUX Audio Speaker Selector for PC Phone Laptop Headphone

I did see several reviews complaining about static when using to inputs to one output. I did experience static when plugging into inputs but not under all circumstances.How I am using this device: I have an XM Roadie and iPhone with dongle as inputs and output to my trucks Line in. I do not get static with the XM and iPhone plugged in together and the switch works as I had intended. I did get static noise when charging on the iPhone from the car through the dongle, the static was only on the iPhone channel and not on the XM channel. I did try changing the iPhone dongle and found that when using a T adapter on the iPhone and charging with the an Apple lighting to 3.5mm no noise. The Dongle that did cause the noise was a pigtail with charging and 3.5mm all in one connector.Update: I added a Ground Loop Audio Noise Isolator, Noise Filter to eliminate any static noise or hum. Audio quality is clean now. I have noticed that the when switching sometimes I do not get both channels, the switch maybe starting to fail. I will investigate further and update when I know more.

All these years, I've been plugging and unplugging the cables to my computer speakers and computers. This device is so simple and works perfectly... and it's ridiculously compact.

I liked the switch verey simple and small good to hide, works great for what i needed

Simple, sleek design. Totally functional; cuts one line completely allowing the other to transmit its singal (no interference). You can be creative and stack these switches if you have two sources going to two outputs (you'll just need a male to male connecting jack [ no massive switch box needed]). If its too complicated to remember, use file folder stickers to identify the various functions. Professional solution to your "twin" channeling needs. Thank you, Coo(L)idea!

So I bought this to switch between two computers on my desk to share one speaker system. I didnt notice it at first because I was excited to now have to use 2 sets of speakers. But then I notices a low buzzing noise. Turns out its this switch. If I unplug one of the computers from the switch, perfectly clear sound, but if both are plugged into the switch, annoying background noise. I tried switching ports, cables etc, the problem is the switch. Turns out it's creating a feedback loop and it needs to be grounded.

My speakers only accept 1 input, so I had to swap aux cables when I wanted to hear my Nintendo Switch. This fixes that in a single press, clicking the button quickly changes the input to my Switch. Easy to install, comes with a 3.5 cable, and will sit taped to my desk. The build of the button is also nice.

I works but now my speakers his / buzz. The design could be better as well , all the jacks should plug in the rear.
