Check the link to the list in my signature. I believe Beat Audio has an iPhone cable and some other brands make microphones in the cable. You can use the list as a resource to try and find the right cable with what you need and reviews of the cable. I do believe only 3 of them actually have a microphone on them though.
I'm in need of a mic for my phone but still want to use my quads. Do any of you know where I could find a westone cable with a mic? I looked into the EPICS MIC cable, but apparently the microphone on it lets in a lot of BG noise and is pure crap. Does anyone make custom cables with mics?
