Also I have to rely on the information and "good sound with rich bass" expects, however, it was nothing to hear. Because I know other in-ear earphones that bring far more "bums". Furthermore, I had expected a more stable fit in the ear, unfortunately it slipped still like to 'out. And to make matters worse, a channel is down now to 5maligem operation, that is, they probably go back. I can not recommend these headphones are now.
