Summary: I picked these up on a whim at Best Buy a few weeks back. All in all, it was a good impulse purchase. The headphones are great for commuting or walking, but I wouldn't consider these for anyone looking for a pair of headphones for serious music enjoyment- the sound quality is more than passable and can get quite loud, but there is no richness to the audio.
I have them paired with both my iMac and my Droid Incredible.
Pros: no wires, light, controls on-ear, descent quality, can be used for phone calls
Cons: slightly expensive for the sound quality, skips occasionally
