Excellent pair of headphones that I use on my Sony PSP, Nintendo DS Lite, and even my Samsung T10 mp3 player. They are price a bit steep I will say but they are worth the money. They can collapse into a case that comes included with the headphones. One major gripe I normally have on headphones are the cords that connect to the player. In the past the cords have been very flimsy, weak, and easy to stretch and destroy. With the cord on these Bose headphones it is VERY reinforced and to me honestly unless you are purposely trying to destroy them or simply cut the wire, you can not destroy the wire.

The part around the head of course is adjustable. My only issue with these particular headsets is that they can tight around the head and become unfortable and I have to adjust them from time to time so I don't get annoyed with them. Yet this is probably due to my big head.:)

These sound GREAT and are quite a bit less expensive than the QC2/QC3 phones. And they actually do a pretty good job of blocking outside noise.

Some great headphones from the high-end audio consumer electronics brand. These headphones fit comfortably over the ears and deliver clean, crisp sound. They're conveniently only 5 ounces and come with two detachable cables of different lengths - 16" and 43".

these are bose's middle of the line headphones...still better sound than any other out there. they also fold up and come with a case for easy and safe travel.
