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.

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!

I have computer speakers and a set of headphones. It was a pain to constantly change the plug on my computer and possibly wearing out the port. Now both audios are constantly plugged in. This little switcher a great job a 1 in and 2 out. I hear no distortion or feedback using this switcher.

This switch uses a common ground connection, which creates a loud background buzz/hum when connecting two audio inputs. The instructions recommend adding a costly audio isolator to remove the hum. Save yourself the time and money, and just get one that has a switched ground, like https://www.amazon.com/dp/B09RWB4SZR

Works as it should, no issues

While the form factor of this product is exactly what I was looking for, when the cables for both outputs are connected at the same time, the devices has a high-pitched buzz. If this is due to the proximity of electrical components, I feel like shielding should have been added to prevent the noise. Surely something like this could have been caught during QA testing, unless this is an anomoly and I have a defective item. The only way I can use the device is if I plug one output in at a time, which provides exactly zero benefit over not having it.
