I recently purchased my first set of Turtle Beach headsets (X-31) for my Xbox 360. The sound is amazing, the overall quality seems quite nice.

However, the setup (and the included cords) require me to "piggyback" on the RCA cords rather than the HDMI. So even though the sound is great, the picture quality is diminished greatly.

Maybe I havent searched enough, but does anyone know a way to use these headphones with the HDMI? Or can anyone recommend a nice headset that can be used for the Xbox 360 without sacrificing video quality?

Thanks.
