A:AnswerNO, you cannot use this controller or any bluetooth headset/controller for in game voice chat. From NVidia's site:
"Like other gaming consoles, SHIELD TV does not support mic on Bluetooth headsets due to latency/audio issues with the standard Bluetooth protocol. We will look into trying to fix this in future software updates."
A:AnswerNo. This question has already been asked and answered about a different device. It won't work on anything but the Shield or a PC with a USB connection.
