I'm looking for something like this, only with a pass-through. I use my phone as my media player in my car, so I just have a regular audio cable that goes from the aux port of my car to my phone's headset jack. I've been looking all over for a cable that has media controls on it, or at least a small dongle that I can plug a cable into. The only things I've seen so far are Bluetooth adapters, and that's overkill. I don't want something that I have to charge all the time, I'd like something that is powered by the phone like the headsets are. edit: This is exactly what I'm looking for: http://www.dealextreme.com/p/stylish-headset-w-microphone-volume-control-for-nokia-5800-n8-5230-n86-n97-3-5mm-jack-80cm-cable-54516 The only problem is, that's for Nokia phones. I'm not sure if it would also miraculously work on Android phones, but at that price I might order one and give it a shot.
