am also looking for 55-60inch 4k or Full HD no 3d or curved (because of extra price premium), but I really need bluetooth for my headphones and somehow it's hard to find tv that have bluetooth these days, in my little research, LG has wireless sound sync, which is basically bluetooth but only LG bluetooth products are compatible, so it's kinda like proprietary.
So any suggestions that have generic bluetooth that would connect to any bluetooth enabled headphones? Any brand is ok.
