I have a:
UE65MU6120KXXU
it unfortunately does not have Bluetooth, I have accessed the “secret menu” and it says not supported.
is there a Samsung Bluetooth adapter/dongle that I could add so it can be supported?
I'm in the process of trying to upgrade to the Samsung smart remote control instead.
kind regards
Hi @DoubleDelse welcome to the Samsung Community 
A Bluetooth Adapter is an option, see information here https://www.samsung.com/us/support/answer/Bluetooth
However achieving the best result (re latency) is not always straightforward, some better products available though.https://www.headphonesty.com//best-bluetooth-audio-transmitters-tv/
