Check out the Griffin adapter dongle
http://www.griffintechnology.com/products/headphoneadapter/
It is listed as coming soon.
Just take an x-acto knife or other sharp blade and trim off a few millimeters around the plug on the headphones...
What they need to come out with is an adapter that looks like the iPhone cord (with one button remote and mic) that allows you to plug in any set of phones you want. Come on Apple, everyone knows your earbuds suck.
Heck Apple may as well substitute the earbud cord/remote for the adapter/remote + earbuds and make it easier for everyone.
this is a baffling aspect of the design of the iphone. i could see potentially if apple had made the adapter, but it's not even their own profit if they're using this crazy design to sell a belkin/other 3pp product.
the iphone is sexy as hell, but i'm kind of astonished at the need to buy an 1/8" to 1/8" adapter to make it work with any other headphones.
I purchased a set of the shure headset from the ATTt store, and was very excited owning 2 sets of shure earphones already> ec5's for my ipod 80 gig, and a second set of ec3 for my old 40 gig (I leave that in the car for my car stereo interface, and sometimes I forget my other ipod at home, so a second set of earphones comes in handy) The ATT store would not let me try them, so I purchased them and went to my car to try them out. The sound quality was pretty good until I tried a phone call. Both on my end, and on the callers end sounded like you in a barrel, echo with crackles and pops. I thought maybe i had a defective pair, and tried a second pair with the same results. Returned them without ever leaving the ATT parking lot. I was very disappointed. So for now I am stuck with the stock headphones with a pair of griffin earjams.
