Just a quick question - can I use the Turtle Beach Ear Force Xbox 360 Audio Adapter plus something like this - http://tinyurl.com/y68dwmsk - to get game audio to my non-Turtle Beach headphones? If so, would I need a volume control on my headset to adjust the volume or can I do that on the dashboard?

If I have a 360 E, can I plug my headphones directly in the 3.5mm jack in the back of the system for in-game sound to my headphones?
