I have a Samsung TV, 4k series 6 I believe. Inexplicably it doesn't have Bluetooth capability and I would really like to be able to connect Bluetooth headphones to give us some flexibility with working from home/Zoom meetings with different schedules etc. I considered (and bought) a Bluetooth receiver/transmitter but I've realised that the TV doesn't have RCA or a headphone jack in which to plug the transmitter. The only option seems to be plugging in to the Optical but we have a soundbar and I really don't want to be fishing around behind the TV every time we want to move between speakers. I have read mixed advice as to whether a dongle in the USB port would work. Please help!
