wireless audio solution for home?

[Godospartan]

Alright, here's my setup. i am in the room near the street in a very big neighborhood. i worry my current setup will wake the neighbors if i keep my window open. whether i am using my computer, gaming on my xbox, or in bed falling asleep to netflix shows, my setup is, at the moment, a pair of bluetooth speakers conected via 3.5mm plug to my old RCA tv that i also use as my computer monitor. but i am trying to find out a solution for good balanced sound to wirelessly go from my TV, no matter what's on screen from what source, to near my bed so i can listen to stuff from bed without worrying about volume reachign way out my open window. thing is, bluetooth is not on my tv, it's not a smart tv or anything. so here is my question:

 

what solutions do i have to get wireless speakers, that are good and balanced sound, to be able to connect to my TV?

You may be able to use something like this:

These simply take an analog 3.5 mm input and transfer it to the other receiver with a 3.5 mm output.  With some RCA adapters you could make this work with almost anything as long as you can power them over USB 5.0 V.
