Looking for headphones for jogging, I came across the Sennheiser. Have you since now almost a year in continuous use - primarily for jogging. At first I had the headphones probably given 5 points .. sound is great, ambient noise can still perceive (what me was very important) Upon run well in the ear (mine is still not fallen out once) and the cable is also pleasantly long. Deduction is now available, however, because after just one year, the headphones have a slight loose contact. That now and then it happens, which remains a headphone mute .. a short shake fixes the whole then again .. but for too long they will probably no longer keep :-(
