Anyone know of a cheap way to send audio over say, 10 meters. Must
take a 12v or lower supply and be low power draw. Maybe bluetooth or
2.4ghz, must be be fairly hi-fi.

Particularly something I can obtain in the uk!

Analog or digital in?
Analog or digital out?
Which end (or both?) must be battery-powered?
What is your budget?
What is your quality expectation?
How much latency can you tollerate?
Why not just a wire?
(i.e. what is the application?)
