To go along with my shure e2c headphones and iphone of course I have to get a mic/headphone adapter.

I've had a pair of these for 4 years now. After extensive use (basically every working day for at least 4 hours and frequently taking them on/off) the plastic cracked at the point where I fold them around my ears. Bummer. But, for this kind of (ab)use it's not all that surprising.
