Getting an LG CX tv, is this the right way to setup wireless audio?

[meaFX]

Greetings Head-Fi enthusiasts, after many years living with monitors I finally decided to get a proper tv but wireless audio immediately became a problem I need to solve. Since I'm so used to having everything on the same desk all my headsets and headphones are wired. Here's my use case scenario and how I decided to solve this issue, mind you I'm no audiophile, and the pair of headsets I own are nothing to write home about but still I don't want to spend money on new headsets just because they're wireless.

What I want to achieve;

The TV will be connected to my PC, down the line I'll get a PS5 so I don't want to mess with a 3mt long 3.5mm cable. Since I'm not going to play competitive games on TV all I want is both a PC gaming experience and native TV apps like Netflix, Apple TV App to be lip-sync latency free.

LG CX tv natively supports aptX but not the aptX LL, if I'm not mistaken even regular aptX codec helps to reduce latency. (you can correct me on this)

So based on this I decided to get a Fiio BTR3K Bluetooth Amp and pair it with an Avantree brand Bluetooth Adapter that supports both aptX and aptX LL for PC. I'll not be able to use the Bluetooth Adapter on TV but I thought regular aptX for movies/tv-shows and aptX LL for gaming will be enough.

I own Steelseries Arctis 3 and JBL Tune 210 if this setup turns out how I want it to be I may finally convince myself and get a proper Audiophile headset.

So I haven't bought the Amp yet so you can feel free to correct me or recommend me completely different setup.

Depends very much on the aptX flavor
Latency in ms

Wired 7
SBC 173
aptX 166
aptX-Adaptive 80
aptX LL (Low Latency) 34

Likewise the amount of lossy compression varies.

OK I'm wondering about this too. I have an LG C9. I was reading on rtings.com that for example the Shure Aonic 50 is not good for gaming because of latency. Is this true even with aptX?
