Four conductor headphones mini usb...

[widezu69]

I have iPhone headphones with 4-conductor pins, http://images.appleinsider.com/ipodiphoneav-review-5.jpg (the second one) and was wondering if there were any adapters that will utilize the mic connector on the headphone and carry the mic signal as well as stereo sound instead of just the stereo ones I see all over the internet.
Thanks

I haven't seen any yet but it should be easy to DIY one for around 10 bucks.

You need a HTC ExtUSB 11 Pin USB Connector and a 1 gen iPhone 3.5mm adapter.

The video-out/power/headphone adapter (has 2.5mm and 3.5mm) from my Touch Pro/Rapheal works great and I'm sure those can be had quickly and cheaply. Nice thing about it, is that you can charge, connect data, and use headphones at the same time (which I do to fall asleep).
