i have no home theater system or hd box. only lcd tv and ps3. how can i connect to get a audio output to my headphones while using hdmi video from my tv with ps3

All I can say about Sennheiser wireless headphones is try them before you buy them. Be sure the store has a liberal refund policy.

I paid a lot for mine and they didn’t work well at all. Too much interference from the wireless phone and the wireless computer network in the house I guess. I ended up selling them on eBay for about half what I paid for them.

The way they perform in the showroom is not necessarily the way they will perform in your home.

Otherwise they should work with any audio device you connect them to. Connect them to the audio out on the television or your home theater receiver, however you do your connections.
