Anyone use wireless surround sound setups? Not headphones but actual speakers.

I dont like playing with big headsets on for sound. I much prefer the sound just being in the room with me.
At the moment I just have a free Sony soundbar and sub that came with my 4k tv. It's better than tv speakers for sure but I'd like to see what's possible with some surround sound speakers.
My problem is I cant be trailing wires around the room and we rent so I'm not gonna go DIY on the carpet or walls etc to try and hide the cables.
I've seen SONOS have a multi room wireless setup but the sound bar and sub alone are £1200 it seems. Then I need 2 more speakers on top for the rear.
Does anyone use a wireless setup? Did it cost you a lot just for it to be wireless? Does it cause any issues with gaming?
I run optical to my current soundbar and the sub is wireless. No problems so far with the sub being wireless but i dunno how rear speakers would perform in games. Or how the setup might even function with films and games.
