Summary: Sound lacks richness in high frequencies. Spring-loaded ear pieces: they crunch your head, they are too strong. Music sounds like in a concert hall, but you are sitting too far back. Noice Cancellation is like magic! A+ on that.
Summary: i just bought these at radio shack for $50. the fit is ok but they pinch a bit after a while. the sound is pretty dissapointing. the noise cancellation feature doesn't do a lot and they sound quite muddy. the only thing i do like about them is their size. i will probably return them.
