see all of the great review and get these recommend by a friend , I decide to buy they . I be very disappointed when i plug they in and listen to they . there be almost no bass on these headphone . these headphone have very good treble tone and you can hear every detail of what you be listen to . they be also comfortable . but there be very very weak bass . this be the case when plug they into my computer , my turntable , and my guitar amp -lrb- even while i be play a bass with the bass knob all the way up and everything else down -rrb- , so I think I have to blame it on the headphone . i will be return these headphone and look for a new pair .
