When I first put them in they sound horrible. Super flat, sounded like I was listening through a tin can. Once I figured out the right head sizes for my ears (ake sure you do this. One ear can be bigger than the other) and got a nice seal going, I got amazing sound.
Very comfortable, great sound quality; Comes with a cool little zipper case for storage and six different sets of heads; The foam ones are awesome; Work like ear plugs; Squish them down then set them in you ears and let them form a nice seal; The rubbers ones are nice, too.
Need to grab some more FLAC rips now because 320kbs and V0s don't sound good enough on these and my 595s; Don't really care for how they make the cables these days; Like a foot long from the ear buds to the plug, but then you use a five foot extension; Not a big deal, just don't care for it
