I've become used to the great corded headset that comes with my iPhone (even though the first one lost sound in the left ear and I had to buy another). I love the tiny mic, the whole thing is so light-weight. What I find is that I start to naturally use the same headset when I'm using my MBP - just because it's often round my neck anyway. Wouldn't it be great if I could use the MIC from the headset with the MBP as well? Then I could use it properly for iChat/Skype calls. I'm wondering if it should be possible for someone to manufacture an adaptor that fits the special 4-contact plug on the headset, and separates off the mic part so that it creates 2 normal mini jack plugs, that could be plugged into the MBP headphone & mic sockets. Would be great. Anyone heard of such a thing? I had a Plantronics headset before for VOIP and the thing was so bulky and cluttered, with a long cord, that it was more trouble than it was worth. Second on my list would be a really simple, light-weight USB headset, with a fairly short cord (of course I couldn't use this with the iPhone, I'd just leave it plugged into the MBP). I guess a Bluetooth headset might also be a good idea. But by all accounts pairing and re-pairing sets between the iPhone and MBP is not so convenient, and that's exactly what you'd need to be able to do in a hurry. Anyone else have any thoughts/experience on this issue?
