Delivery of 10 days to novokuibvsheaska. Tracked to the place of delivery. Packing is perfect. Nothing's broken. The quality of the headphones deserves the highest praise. I had to get a little nervous with the first connection. These headphones with built-in lock from foreign connections. To activate with the new device, you need to press the middle button and keep until the LED starts flashing in blue and red. After that, the phone will find headphones. This procedure should be done every time you connect a new device. The headphones themselves are very good .. There is noise reduction. Of the shortcomings, it is not enough volume. (I need louder because of the weakened hearing). The store is very sociable. Answers immediately for any questions. I recommend the seller as very reliable and sociable.
