While I can get to all these wired in with some really long cat5 cables, I’d rather have wireless data to them, so I can be more flexible with their positioning.

I’d like to be able to connect 2 different devices to them at once to play 2 different tracks in different rooms, but also be able to pick which rooms the speakers play in. I’d probably use 4-5 speakers across 3-4 rooms. I’d love to be able to use my phone, PC & TV ideally as inputs.

I can put a pi or such next to my router to control all these if needs be.

Budget is aiming at £250.

Any suggestions?
