So I created this headset over a year and do not lose their quality. By comparison, I bought in Ear recently beats, and these are associated with deffekten already for the second time after several uses for gentle treatment. Everyone wanting Sennheiser headphones are much better in the outer ear and although the two headphones have their different fits, it is noticeably more comfortable in the ear to the Sehn Heiser than umgekehrt.Darüber addition, the Sehn Heiser an almost as good sound quality as the beats. The bass is not so massive, but now that is not as apparent in weight. Here agrees the Qutität with all the trimmings. Keep in a case with the included carrying case, the clip, so it does not hang around and fit for right's.
