HOW DESIGN HEADPHONE WIRELESS CIRCUIT ?

I think some ready made AM & FM IC are available
You can use that.
You have to search on google.com

Do you want it to be stereo or mono? Mono is simpler: u can build a very simple FM transmitter, and then listen to it on a small portable FM radio. For stereo, you can build a transmitter using a BA1404 integrated circuit. There are all types of FM transmitter circuits on the net, mono and stereo. Hope this helps

If you check the book COmmunication electronics
by roddy & collen
PHI publication
They have explained AM & FM communiaction circuits nicely
