Connecting Philips SHB7250WT Bluetooth Headphones to LG 47LB650V TV with External BT Emitter

I have a LG 47lb650v TV and Philips SHB7250WT headphones. The TV has bluetooth and BT connects to my LG LAS550H. But unfortunately, the TV does not want to connect to the headphones in any way. So I bought a separate BT signal emitter.
No matter how important it is to emit BT audio signal. I want to connect it to the headphone output from the TV and usb to the TV so that it can be charged all the time. That's how I came up with it.
Now the question. How is the BT signal paired? Headphones-emitter? Neither on the headphones nor on the emitter it is not possible to select the signal / device as it is for example when pairing with a smartphone. Can it go automatically?
Thank you for your help and best regards.

If both devices, ie this new BT transmitter and earphones support the NFC (Near Field Communication) mode, it is possible to pair these devices.
Please check the instructions of these devices.
If they do not support NFC, I hardly see the possibility of connecting them.

Well, this is concrete Thank you. I think I'm saved because they have NFC

Just remember that when pairing, both devices must be very close together.
As the name of this pairing technique itself indicates.
As far as I remember the specification, the maximum distance between the devices when pairing should not exceed 30 cm.

Yes. Yes. Thanks. I've already read about NFC. I hope that it will work Thank you again This is very valuable knowledge for me.

Hey gentlemen, since it's a Bluetooth emitter, it must be pairable and it is definitely described in the manual. Will it connect automatically? Yes it should, but we all know the problems that some bluetooth devices sometimes have. There are cases that they do not connect or even do not parry, or a specific couple regularly stubbornly disconnects for no reason. Write how it works for you
