A:Answer If I understand the question correctly, you want to hear the TV through bluetooth headphones. If so, you'd want to get a bluetooth transmitter and connect it to your Samsung audio out port, then connect your headset to the transmitter rather than try to do something through the soundbar. I use a bluetooth transmitter for private listening frequently, but you'll ideally want to invest in a good transmitter with very low latency, or you'll notice the sound lagging slightly behind the image on the TV. Even with cheaper versions, it's not bad enough to be a deal killer though. I don't have any specific transmitter to recommend, but I believe they are available through BestBuy.
If you are referring to the soundbar's bluetooth connectivity to your phone or tablet, that works just fine.
Hope this helps.
