They have a spring on the "crossbar" that can clamp down on your head and become uncomfortable after a while. That may depend on the size of your head....my hat size is BFH
Otherwise, the X is a generation old and the price seems high. You can never go wrong with Dave Clark's. Try a few out if your local FBO or someone will let you borrow.

Guess I'll stick with the others. Using the Zulus on an Atlantic crossing in the Challenger was awesome.
I've seen guys wearing the UflyMic without the "TSO earbuds" with Feds observing and the guy could really care less. When I talked to a lightspeed guy at a tradeshow he said the headset meets TSO guidelines but they do not want to have to pay the government more money that would have to be passed onto the buyers.
