I have be go through several pair of open , on-ear full-size headphone but I need to get earbud that block noise and do not leak like crazy -lrb- like my open one do -rrb- anyways , I be a bit skeptical when I order these -lrb- after read comparison on head-fi forum -rrb- but I have be nothing short of impressed . here be one tip - if you get in-ear earbud make sure they come with different size earpiece . these headphone do . this be extremely important !!! if they do not , plan to buy some separately . everyone 's ear be different in size so make sure the earpiece fit right . sound = 4\/5 Bass = 4\/5 Noise cancelling = superb for this price point -lrb- mine be sixteen -rrb- you can not find something that be this sturdy and with this sound quality . they be awesome ! earbud MAY induce massive WAX ATTACKS : also , if you not use to wear in-ear earbud - be aware - because the earbud be a `` foreign object , '' you ear canal might -lrb- like mine do -rrb- produce ear wax to combat it . yuk ! I clean my ear before and after i use these guy . bottom line : get these headphone - they be affordable sturdy sound great ample bass isolate well come with different size earpiece well design - leave be shorter than the right , which wrap around behind you head also - you can lie down with they in you ear because they do not stick out like other do
