So in the headphones "cheap" quality is rarely appointment. The fear is always to be with a defective unit after 2 months ... Here after 9 months of almost daily use (taking care to wrap the cable though) they still work. Good sound quality and the headset is working correctly. We must approach the microphone against by the mouth so that recipients are going along well. (1 star less for it, even if it reduces the emitted noise)
