Hi, With my iMac, I have Swan M10 external speakers that I love. I also like to use headphones sometimes. My currrent solution for switching from speakers to headphones (or vice versa) involves physically turning the computer, disconnecting one input in the headphone jack, and putting in the other one. I am looking for a splitter that will a) is long enough to rest on my desk instead of dangle down from the back of the computer b) quickly allow me to select which audio output device I want to use (without playing through both, which causes problems: either tingy sound playing through the headphones I'm not using, or having to turn off the speakers I'm not using) Is there a solution for this? Thanks in advance!
