I had this earphones for 2 years and I must say, that I was really satisfied with it. With the possibility to change bass you can choose what really fits you and I must say, that the bass was really nice, clear and deep (I used the middle one).   Only cons which I found are: hard cable - it can easily pull out the phones from your ear... size - the phones are little longer then most of the others, so e.g. under hat it's not very comfortable, but acceptable, it's also easier to pull them out by cable...   Otherwise I really enjoyed them :)
