The headphone could be these Avantree ones I just found on Amazon.

I would get a pair of these excellent bluetooth headphones
In fact that is exactly what I did at my house in a room like yours.
Cheap easy and very good sound!

no lol, bluetooth has lag and you’d be creating an expensive monster of cables. you buy an avantree kit like everyone else
