Its unlikely you'll find anything to suit your requirements.
For example how would you power such a device? you need the power to
transmit the Bluetooth signal.
If you want to use your Bluetooth headphones with your MP3 player you're
going to have to get a player that can use Bluetooth to transmit to the
headphones.

I have an mp3 player with 3.5mm headphone jack.
I have newly acquired bluetooth stereo headphones.
Does a device exist which I can plug to 3.5mm jack and bluetooth to my
headphones?
