A:Answer YES & YES. #1) this device has USB, HDMI with Audio Return Channel (ARC), ethernet, wifi, BLUETOOTH*, 3.5mm audio jack, & optical audio. However, the TV itself can only handle one directly connected bluetooth headset at a time, but there are workarounds for sharing a connection or using multiple variable connections for two or more listeners. If you intend to do any major computing or gaming etc, you might want to give your display focused TV a break and hook up an equal or better powered computer or gaming console (XB1, PS4, & Switch can handle up to 8 controllers &,or headsets). * Here's the general details for the bluetooth on this TV -- https://www.amazon.com/gp/help/customer/display.html?nodeId=GSBSBL44Y4QM59FV
