In general, everything is fine, but I have Marshall Major 4 headphones, and with the wire that went complete with the charger on the wireless, the headphones do not have a light. symbolizing about going charging (the phone charges normally). With my wire (which is not for data transmission), the bulb lit up and immediately disappeared. It may be necessary to raise the wires, if I find the right one, at least the complete data transmission will be useful.
