Turtle Beach X11 Headset $68 at EB Games or JB Fi-Fi (Approx 23% Discount)

I picked up a pair of these for the kids the Thursday from EB games for $68 (normally $89)
Seems that EB has pretty much sold out. (SE metro melb)
Tried the $68 price match at JB, no issue for the second pair.
I should have just gone to JB first to price match as it would have saved mey time and driving.
JB had plenty of the X11's on the shelves.

it looks as though the X11's work on pc as well as xbox?
