Headphones quite match my expectations. The +: Its ergonomics are very good, the sound quality is not bad and respect severe. it also reduces external noise sounds. It is compatible with the iPhone, which can replace the headphones "low end" of Apple (a shame, considering the price of the phones). The -: No volume control at the microphone A comparable listening level at In-Ears Dr. Dre but 10x cheaper. Good quality / price ratio, headphones to buy the "ears" closed.
