Wireless Audio Transmitter / Receiver - any good recommendations?

Hello! Hope this is a good sub to ask.

I have this device, [Amazon Link], it's a wireless Audio Transmitter / Receiver combo, working on 2.4Ghz. It sounds nice enough, good enough for me at least, and I use it so that I can plug the TV (Optical or 3.5mm) to the Transmitter, and then plug my wired headphones to the Receiver, so that I can use my wired headphones "wirelessly" across the living room. The reason I use this particular (wired!) headset is that i like how it sounds and for comfort (it's a Sennheiser open back, anyway irrelevant to the post).

I have a Sennheiser RF headphones as well, which is made for the exact use case I'm trying to do. But basically, I don't like those headphones. Anyway, I think that's mostly irrelevant and I'm just adding this bit to head off comments to get those instead (I tried!!). Unless there is an actually available, open back wireless TV headset that can meet my use case, then I'm open to THOSE suggestions. :) Sennheiser used to have the open back RF headphones, but I can't find them anywhere anymore. It seems to be discontinued.

Going back to the device though, it works, but I find it disconnects often. And doesn't seem to auto-connect by itself. I have a way to quickly turn on/off the receiver, and that restores the connection, but it's annoying. I think it's the device that's the problem, because I believe the Sennheiser RF headphones works on the same frequency(?) and it never disconnected to me for months. But I could be totally wrong about that. Right now I think the problem is that this particular device just isn't that good.

So I was just wondering if anyone has any experience / recommendations for something like this? Thank you! Sorry for the long text!
