To pair Bluetooth headphones or a remote with the TCL QM8, open the Google TV settings for remotes and accessories, put the device in pairing mode and choose it. If it fails, remove the old pairing, restart the TV and the device, and try again. The TV can connect to one headset at a time, and a Bluetooth headset left on will take sound away from the speakers. Interference from Wi-Fi and USB 3 devices near the TV can cause stutter, so move other devices. Update the TV and the headphones. For audio lag, use a headset with low-latency support or a wired connection, since Bluetooth adds a small delay.
