Build Wireless Speakers from RF Headphones

Shows that with a little ingenious wiring, a pair of headphones can become a pair of low-power rechargeable wireless speakers.

For this mod you will need:
One or more wireless headphone sets with rechargeable bases (we used inexpensive Sony RF headphones) 
A soldering iron 
Two channel socket and plug connectors for power 
A miniature slider switch 
Some thin cabling 
Plexiglas and hot glue or other material to build speaker housings 
A dremel or similar to make openings in the speaker housings

If your artsy friends have been begging you to build them wireless speakers on the cheap for their Burning Man installation, read on. If not, it's still a helluva lot of fun, so read on anyway!
