First time, plugged in as instructions said, no problem. Connect 2nd controller to use headphones, stops working. Disconnect all and reconnect as per instructions, now controller turns off as soon as plugged in, and you can't power it on otherwise it'll bypass the adapter and connect to the console (xbox for me) straight away. Tried 3 different controllers (2 USB type-C, 1 Micro-USB) no luck. Terrible product and a waste of money.
