What is a simple way to transfer an audio signal wirelessly from a headphone socket to a stereo input socket?

I am trying to transmit audio wirelessly for a school prank. Any suggestions would be appreciated.

There are wireless headphones that are a radio transmitter and receiver. You could take the receiver and connect it to any device you want. It may not go very far, but it would go a decent distance.

Not simple. Would require a radio transmitter / receiver or line-of-sight optical modems. If you had a spare BlueTooth headset you might be able to hack that? L
