I'm selling this because I bought a different one. Both Bluetooth and 2.4GHz work without any problems. The battery doesn't seem to be extremely bad, but I haven't measured it precisely, so please understand that this is a used item. Everything in the photos is included. I don't think there are any missing items, but please check the photos to confirm. The box is included, but please note that it is slightly crushed. #Gaming #WirelessEarphones #Headset #USBdongle
