Review: Nice quality, works for my needs. (Beware some inputs may induce static) - 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.
Review: Great little audio switch - I'm using this inside my car to switch between an MP3 player and other devices to play on my stereo aux port. It works great and doesn't have any interference. It's small and doesn't get in the way of anything. Sounds great even when switching between two active devices playing audio. The button is small but not difficult to press. Feels good quality for what it is and was a good price compared to the other offerings. I recommend it.

### ⭐⭐⭐⭐⭐ Fixed audio problem.
*by W***A on March 30, 2026*

I had two sources of audio that need to go through one amp. Neither source had an auxiliary out. They did have headphone jacks, so those are now the audio outs. Switching back and forth is easier than unplugging and replugging one source to another.
