I have be use the oe2 for about 5 day and , so far , I be very happy . I 'll start off by say I be not a expert on audio product . in make the purchase , I be look for headphone that would deliver clear , big , rich sound with some solid bass . that be definitely what I get with these . other review note some disappointment with the bass production . if you be look for boom , bass-heavy headphone then this might not be you choice . however , by play around the eq setting in iTunes or you music player , you can still get some very big , solid bass . on music track I listen to with a solid amount of bass , with my eq bass setting turn up a bit , I get a really nice , rich , full bass with great range . sound great . I personally choose the one-ear versus the over-ear design because over-ear headphone hurt the sensitive area behind my ear after only a few minute . the on-ears be incredibly comfortable , very soft , and very light . after a couple hour of wear I do feel some slight pressure on my upper earlobe , but it go away quickly when I take these off for a minute or two -lrb- probably should do that anyway -rrb- . they do leak sound a bit , but that be no surprise . I be not sure if the over-ear design would diminish it . they be not cheap , but I do really enjoy the oe2 . very big , rich sound , and you can get some really great bass production by play around with eq setting to you liking . I would definitely recommend these .
