If you are looking for wireles headphones purely for TV viewing you could consider the Sennheiser RS series. Not bluetooth but wireless nonetheless and generally better for Tv due to having less hiss and latency issues. Otherwise you could go down the route of using 2 Avantree Saturn Pros and using a normal pair of headphones. If you want Bluetooth then the Def Tech I just reviewed would probably be a good option. Good bass response with NC on and no notiecable hiss. Of the ones you mentioned the I have tried the HK BT and the Logitech UE9000. Both had good bass though the logitech was somewhat artificially boosted. Both had a pretty noticeable hiss however.
