You can get in-ear "head"sets, like Clarity Aloft and a few other brands, for much less. And their passive NR is supposedly better than a normal headsets ANR. If you can cope with the feeling of having something in your ear canal, that is.
I have no experience with them myself but I'm currently taking a good look at them. I've got a PNR headset at the moment and want to upgrade to something that's better suitable for aerobatics.
