A relatively simple device, but this does exactly what it should do, at least for my purposes. It got rid of some annoying noise that was otherwise in the line as well, so bonus points for that. I approve!!

Has a massive downside, the knob wont get to mute, it will always let pass a small amount of audio. That is a dealbreaker for most situations.
