I recently purchased a turtle beach XO 7 headset and downloaded the update for the controller as well. At random times the controller will stop working and I'll have to remove the batteries then place them back into the controller to get them working again. I've tried on multiple controllers and the same thing happens on them as well. I've tried different batteries and such also. Not sure if anybody else is having this issue or not but it is a pain the in *** especially when it seems to be happening every 5-15 minutes at random times.
