I am currently reviewing Bluetooth headphones for my LG Webos based smart TV (43LJ617T). I saw a lot of forums and blog posts discussing about this proprietary technology in LG TVs called “WIRELESS SOUND SYNC” which only allows (actually restricts) headphones supporting this technology and all the other headphones don’t work with it. There are also reports from people which say, they were able to pair their headphones with the TV, but no sound would come from the phones.
I have found no headphones in my research which support the LG TV WIRELESS SOUND SYNC feature, accept some premium LG headphones. So I decided to finally check some Bluetooth headphones with my TV and check for real what the issue is.
Turns out all this TV WIRELESS SOUND SYNC gamut is really a farce. I tested a very basic BoAt Rokerz 600 headphone shown in the picture here and it just worked. 
The connection was straightforward and sound was streamed without any issues. This is a pretty basic headphone and their site doesn’t even mention what version of Bluetooth these headphones are made for. I did a quick BLE scan from my android phone using a scanner app (there are plenty on the playstore) and though many other devices showed up under BLE, The BoAt headphone shows as a Bluetooth Classic device. That concludes, my TV works with a headphone with less 4.0 Bluetooth version. I see no reason why it would not work with any version and make Bluetooth headphones, as my TV is a 2017 model (BLE came in 2013). So anything audio + Bluetooth should just work.
I have reached to the conclusion that all the fuss about LG WebOS TVs not supporting headphones without some magic wireless tv sync technology is absurd and unbelievable. Ill update this post once I review a Bluetooth headphone with BLE support i.e. Bluetooth > v4.0.
Update 1: I ordered a Meizu EP51 bluetooth headphone from Gearbest. Works perfectly with my TV. Sounds really good and there is no audio delay from TV to the earphones. This is Bluetooth4.0+EDR headphone.
Update 2: A cheap KZ Bluetooth audio cable for KZ wired headphones too works fine with this TV I own. A Bluetooth version: 4.1 device.
Update 3: Here’s more to it. Check this out:

I spoke to one of the LG store guy and he says If your TV model is 2017 or above (with a WebOs version 3.5 and above). Any Bluetooth 4.0 or above headphones should work.
That’s all for now, if you have any more info around this, leave your comments below.

Believing your blog i purchased boat rockers 600 tried a lot to connect it to my( lg 49uf 850t ) smart ultra hd 4k tv but failed the boat headphone came with Bluetooth 4.1 version as mentioned on operator’s manual and the TVs Bluetooth version shows 4.0 in TVs details

That’s sad. Also looks like your TV has an older version of webos. Its webos 2.0 While the one I have is WebOs 3.5 or beyond that. Do check if there is an OS update available for your TV. I have 3 BT headphone, one from Boat same as yours, second called KZ a purely Chinese (ought to be cheap audiophile :D) brand and the last is Meizu (definitely Chinese) brand. They all work without any issue with my smart TV.

I have UJ6300 it means, manufacturing date is 2017. But it doesn’t have any Bluetooth option! Connecting any Bluetooth headset to this TV is impossible.

You can always use a 3.5mm stereo to bluetooth transmitter. I don’t own this but has good reviews and you can try it:

I have Lg 43 UJ630V UHD 4K TV. I’m going to buy Sony WI-C300 headphone. Do you think it works ? It has 4.2 bluetooth version. My WebOs version is 3.7.2.

If your tv model is beyond 2017 it should work. Also you should have an update available to webos 4.5.

Hi,
May be thinks have changed. I have a LG 42LB650V-ZN and two Bluetooth headphones: a Sennheiser PXC 550 and a JVC HA-S90BN.
Both don’t work.

Ofcourse he would say that. I have 2 cheapo bluetooth headphones (real headphones with earmuffs etc.) and they work perfectly with any BT audio device I have. Except my LG55 inch TV. No pairing, no sound , nothing. LG definately creates issues with BT headphones on purpose just so you’ld buy their brand stuff. The exact same thing with wireless keyboards (the ones with their own dongle). Only LG and Logitech keyboards work on the TV. It’s a scam.

Can I somehow connect LG UJ 6300 audio to my LG CM4550 stereo? Stereo has LG tv listed as a function but no Digital Optical. Please help!

Your TV doesn’t seem to have bluetooth but has an optical output, while your Stereo doesn’t accept optical input but accepts Bluetooth 😀
The only way out wirelessly seems to me is to use a bluetooth transmitter at TV and link it to the Stereo.
