Making Your Headphones Wireless?

Chuck Chunder asks: "I've recently been looking at getting some wireless headphones of the RF rather than infra-red variety. After looking around for a bit it struck me that I don't actually want a whole new set of headphones. I already have a nice pair of headphones as well as earphones. What I really want is an RF transmitter and a small clip on receiver that I can plug my existing headphones/earphones into. The problem is, I can't find anyone selling what I am describing, even geeky places don't quite have what I'm looking for. Does anyone know/have experience of such a product?"

"I see several advantages to this:

• Adaptability: I can then use earphones/headphones as appropriate for the activity, or possibly use it as an RF link between hardware in different rooms
• Replacability: If I damage the headphones I only have to replace them, not the whole headphone/receiver unit; this bit will hopefully lead to...
• Lower costs

Has anyone seen something like this, before?"

Have you considered a Walkman for receiving?

Building a radio emitter is not very difficult (I remember having an electronic kit when I was young with 60+ different circuits you could build, and one of them was a radio emitter). Ideally you'd choose it not to interfere with your local channels, or some neighbours could become upset if your power is too high.

Then, on the receiving end, a small walkman is all you need. Plug your headphones or earphones, and there you go!

Of course, the quality of the transmission will vary depending on the quality of the hardware and which frequency you choose (near or far from some other channel).
