Xbox 360 headphones recommendations?

Can anybody recommend some good headphones for Xbox?
Wireless preferred, price permitting. Wired would be acceptable as long as logistically ok; cannot leave headphones permanently plugged in due to childproofing requirements. Won't be practical to plug in at back of Xbox every time I want to use them. Xbox live chat support is prerequisite.

I've been looking at the Turtle Beach offerings, but I'm unsure about connectivity.?Xbox is connected directly to TV with HDMI. Audio goes direct to TV via same HDMI, no separate audio hardware is involved.

It looks like top end turtle beach wireless headphones use the optical audio output from the Xbox. Will the Xbox drive both the optical audio output and the audio via HDMI output simultaneously?

The turtle beach x31 has a 3.5 mm (analog?) input jack. Do I need some PITA breakout cable from Xbox AV output? Can Xbox drive both analog and HDMI audio simultaneously?

Turtle beach x41 looks very cool, optical audio input, but earlier question remains, will the xbox drive both outputs at the same time? But the x41 is crazy expensive. (although mightyape has it at the moment for 249, still pretty pricey)

Any other suggestions or recommendations?

Thanks,

Cheers,
Joseph
