Since I was looking for good headphones and a good headset for my iPhone, I have decided also due to some very good test results, for this model. Sonically, these headphones are definitely take a front seat with. The sound is clear, powerful and very rich in detail. Even the users of some poorly rated (weak) Bass is not negative, I noticed, and I hear all these headphones from classical to jazz to hard rock and metal and have never missed the pressure in the lower frequencies. From comfort her headphones are perfect. I quickly found the right pair of five supplied silicone essays and got both in sports, as well as all other activities the perfect fit in the ear. The speech - and reception quality than headset is also very good, my callers and I never had any problems. Only the location of the button to answer calls or to stop or start music is extremely unfortunate choice, since it sits very deep and it is sometimes very cumbersome and tedious to use this. This is especially in winter, when one is attracted thick and the headphone cord under your clothes bring, extremely cumbersome. Therefore, "only" four out of five stars.
