Looking for a way just to turn off my headphones when not in use. Something that wont cause a quality loss. I found this and read good things about it but I can't find this sucker in stock anywhere. Its been discontinued. What else can I use? I am trying to keep it simple. I found some that have volume controls etc which I don't want. I just want a way to turn the headphones off without having to get up and unplug them from behind the PC every time. Thx for any advice!
