…but don’t have a headphone jack, Turtle Beach’s Ear Force DSS works quite well on a variety of inputs.
I’m using mine to listen to my Blu-Ray player with headphones, and it works quite well. It does, of course, cost about two thirds the price of a cheap Blu-Ray player, but it beats by miles the extra cost of a computer system with blu-ray built in.
UPDATE 10-22-11: Being a Dolby product, the Earforce doesn’t like DTS sound. To use it with DTS-only Blu-rays, you must go under your blu-ray players’ menu and convert the DTS sound to PCM.
Yes, if it’s not one thing it’s another.
