Delivered within the specified time. By courier to the door, packing whole, box and interior decoration is very high quality. The headphones themselves are charged. Connected quickly. Sound worthy, when setting up the equalizer on the phone, you can be pleasantly surprised by the quality of the sound. The microphone is very mediocre-as a permanent headset will not fit, but sometimes to answer a short call-rules. There is not enough case for the compact transfer of headphones in the backpack, but this, rather, a nice bonus would be rather than an obligation. For such a cost-more than worthy.
