This might be the best idea yet. Forget about having to buy whole new speaker sets for your house as you try to ditch the wires. Beep will turn your existing speakers into wireless ones, along with receivers and docks. All you need is this handy attachment, and a speaker or receiver with an aux input, RCA jack or optical input. Then all you need do is connect it to your wifi, using the accompanying smartphone app (iOS and Android) and you’re good to go.

The sad thing is that it's shipping to the US only for now, but keep an eye out for updates.
