2 out of 5 eggstapped out in 2.5 months

Pros: headphones feel ok.. not the best but ok. Sounds GREAT!! Has like a rotater clip that you can attach to the cord of your headphones and pop it onto your shirt. Black and Yellow.

Cons: It is NOT a durable peace of equipment. Had it for 2.5 months and both (left and right headphone) plastic pieces between the ear buds and the cord are very flimsy. A $20 headphone can do better than what this product could muster. $60 is pretty steep when i got it, but if you like spending go for it. Maybe you can have it last 4 months if your really gentle or maybe put it somewhere and forget about it.

Other Thoughts: It has a lot of accessories which is a plus but if you find yourself adjusting the headphones too often..STOP even if your gentle, just STOP

3 out of 5 eggsNot as good as you would expect

Pros: Good sound and a comfortable fit

Cons: The good sound is lost by the inability of the behind the ear holder to hold the buds close to the ear. The comfortable fit is compromised by the ease by which the rubber bumpers fall off of the ear buds.

Other Thoughts: I wish I had tried one of the other versions of these head phones because the mic and cord are really good, and they seem to be sturdily built.

1 out of 5 eggsBeware

Pros: Appear to be a very nice piece.

Cons: Apparently the remote and mic are for Apple products. Keeps shutting my Zen off. Does not work with my mp3 player.
