Wireless audio for LG TV

[joker08]

I bought a second-hand TV from a friend, its a LG smart 55inch https://www.lg.com/za/tvs/lg-55un7100pva-uhd-4k-tv .
Problem is, it only has an HDMI ARC and an optical out for audio. Doesn't have Bluetooth or a aux or RCA out.
I want to be able to connect my 2.1 speakers to the TV occasionally or connect my Bluetooth headset if needed.
I saw some DAC online but i am not feeling very confident about the products available. Also I dont want to spend much on a AV receiver because it wont be used much. What are my options here ?
Edit :- my budget to tackle this situation is around R300.

Does no one have any cheap solutions or work arounds? I guess then my only option is to use the MI TV box for watching movies

I got the model wrong this is the correct one, but the below one also says Bluetooth as yes. I am wondering why there is no option on the TV

Awesome, there might be a delay though in speech so check if there is an audio delay function to adjust that.
