Summary: i had bought it last July and have used it continuously from then. And the only thing that I can mention is that it is very good. The sound is clear and the bass is very good. The mic given works fine. I have been using it with my Lumia 525 and now Lumia 730. Go for it!
Excerpt: I was kind of sceptical about buying these at first simply because it looked like it would fit quite awkwardly. However I've found that they're really comfortable and light- as in you can just about feel them when they are in. The mic on it is really handy (as it would be) & as a lover of loud music, these earphones are more or less perfect.
