i don't even know if something like this exists but i'm looking for a 5.1 surround sound system that is totally wireless. no wires especially for the rear speakers. does such a thing even exist and has anybody got/seen one? i want to be able to connect my iPhone 13 pro max to it. i miss having a surround sound system but i don't really want a wired one because we have a 6 month old pup and she's somewhat of a chewer so really the less wires the better for obvious reasons.
