I get this headphone about 1month ago . just 99 $ , it be a good deal , but it doesnt work good with mp3 player or ipod , you need a headamp for this headphone . when i use with home theater system , it easy to drive this headphone . this headphone make treble so good , mid be ok , and bass be very strong . THIS be a good deal for 99 $ , but you need a headamp to drive it
