If you are frustrated that your sweet High End headphones don't work in the iPhone's jack, go out to Radio Shack and get a 12 inch long 3.5mm (1/8th inch) stereo jack cable that has the in line volume control - I bought mine a while ago but they can't be more than 5-10 bucks. Shave off just enough of the black plastic at the male end (that goes into your headphone jack) to make it fit, and voila - you have an adapter that sounds great, has a built in volume adjustment so you can leave your iPhone in your pocket, it's cheap, and you don't have to cut up your actual headphones, possibly voiding their warranty.
