these headphone have be pretty good for I for a little over a year . they have give I a sore head after extended use , but nothing too severe . my main issue here come with the retractable headphone cord go bad , and just outside the one-year warranty , to boot . I have be the only one use they , and not in any way that should harm they . the left ear have begin to stop work , and I have to twist the cord around to get any sound in it at all . all in all , good headphone for a little over a year , but watch out for the headphone cord give out .
