If your PS3 does not recognize the headset under Settings > Accessory Settings > Audio Device Settings, or it does not specify 'Turtle Beach Stealth 400 Chat' in the Input and Output Device fields, please try the following:
1) On your PS3, go to Settings > Accessory Settings > Audio Device Settings.
2) Power off the headset and disconnect the transmitter from your PS3.
NOTE: Do not navigate away from the Audio Device Settings screen.
3) After 15 seconds, plug the transmitter back into a different USB port on your PS3 and power the headset back on.
Your headset should now be properly recognized when you select the Input and Output Device fields.
Be sure to position the microphone boom directly in front of your mouth for the most effective voice chat.
Please check that all PS3 settings are configured properly by following the setup instructions in the Stealth 400 User Guide (pictured below):
