I have a pair of (wired) Sennheisers (that I believe were about $150), but I pretty much only use my Sony Wireless Headphones 2.0 that were designed for Playstation, because they honestly sound so much better. I paid $115 for them here in Australia, so they are likely even cheaper when you use real money.
I'm not sure how they would work with a TV, but they come with a USB bluetooth stick that I assume would be plug and play. if I have a chance, I'll try to see if I can get them to work on my TV, and bypass the Playstation.
