I have bought a set of these and they are amazing! ive had Bose and Beats in the past but these ones just have so much more clarity and you hear things you didnt even know where there in the first place.
Im very very impressed with these earphones and although they were expensive, I will NOT be replacing them any time soon!
I would recommend these to anyone since the earphones handle very well different EQ settings on my iPhone such as bass boost, Rock, Pop etc.
One negative is some noise from the cable when its rubbing against your clothes. However, I have not come across an in-ear earphone that does not generate some noise - if this bothers you, then i would go for over ear headphones but they are not as practical to use all the time I find.
