Hey there, if your controller joystick is drifting, please try removing the batteries for at least 2-3 minutes to reset the wireless link. Please also be sure to use new or known-good batteries in the controllers. You can also try unpairing the controller from the headset and then re-pair it following the steps here. For this issue, you may also need to check your play area for any power cables, appliances, fluorescent lights or wireless devices that could cause wireless interference with the tracking. If after this your controller is still drifting please go ahead and do a factory reset.
