I've got the same problem here with a set of logitech x530's (5.1). The problem is that the headphone port is just a passthrough back to the source. It is not amplified or powered in any way. Thats fine for PC's, for which you can use the PC volume control to control the headphone level, but unfortunately is no good for the xbox, as it's output needs to run through an amplifier (which the speakers have). Or something along those lines anyway (I'm no audio expert, but that's how I take it). I'm currently looking for a cheap solution to this, and for me it looks like the easiest and cheapest way is to just make myself a crappy little amp to boost the headphone volume.
Another problem with this setup is by using the logitech adapter you are losing 5.1 sound (unless you run through a decoder). The adapter will just output stereo to all speakers.
1.Thanks for the response,so if you dont have the adapter hooked up like I do,what kind of setup do you have?
2.So if I added an amplifier I could control the headpone volume? If youd be so kind,could you give me a link to a suitable amp(just to get an idea) thanks a lot
