I bought some refurbished TURTLE BEACH EAR FORCE X41 headphones off ebay.
Pros; - Really good sound. - The transmitter plugs into my optical out on the TV but can use a headphone jack as well. - The transmitter is USB powered which is great since its one less adapter to have plugged in.
Cons: - I do get a bit of interference from my Genius WiFi which is in the same TV cabinet. This wasnt a problem when my router was in the kitchen. - The ear cups are super comfortable but are rather big so I suspect a bit of sound may get out if you are watching TV in bed.
