[rib]

a few moths ago i read about a new headphone which had the mp3 player built it, it looked like a closed circumaural, i cant find it anymore and now im wondering which built in mp3/music player headphones do exist and is any of them good?

I know this isn't even close to what you're looking for, but I know the Oakley thumps are headphones/mp3 player/shades all in one!

There are headphones by Macally that are cordless and you can put your ipod or sansa in the headphones and jam out. I haven't seen reviews of these though. Looks too heavy for my head!
