I spend at least 10 hour a week in these mix music professionally . I have own mine since the late 80 and have two pair : one for home and one for work . I have replace the earpad about every 8 year . these be quite simply one of the best ten product I have ever own . the sound quality be unparalleled . they be efficient enough to be drive loud from a computer or a ipod . I have a super large head and these be very comfortable . those of you complain they be too tight do not understand how to adjust they - pull the earpiece down if they be too tight . I have never find a better pair at any price . the fact that these be under $ 100 , last essentially forever , and sound superb , be a modern miracle . flat frequency response as high as any human ear can hear and lower than most any equipment can produce , and yet the sound be please from just about any source . buy a pair of they without hesitation . you 'll never regret it .
