How to Connect Wireless Headphones to Sony Home Theater System?

Hello, I'm a new to all of this HTIB and connections so i need some help! I have my Sony Home Theater System connected in the following way HDMI output to Samsung LCD 46' TV and the Audio of the cable box goes into the Sony Home Theater System and i have my computer and PS3 also connected to the Sony Home Theater System via HDMI. Now the problem is there is no connection for headphones all the sound goes directly to my 5 speakers. I would like to know what i can buy or do to get around this and connect my Wireless Headphones.
