Sell cool headphones from Huawei. Wireless. The sound is excellent (you can check before buying). Great as a headset due to the presence of the 2 microphones on each earpiece. No problems connected with any devices with BlueTooth 4.2 (IOS, Android, Windows...). Stuttered my headphones are only in the area of Central Department store, apparently there s a lot of interference.Full set ( box, check, nozzle, cable, type-c, instructions ).Reason for selling want to switch to headphones, because phone calls to a minimum.
