Unfortunately you kinda get what you pay for in this segment. Sorry for the cliche.
I have 4 ANR headsets in my plane currently - one each from Bose, Lightspeed, David Clark and an el cheap-o model from Gulf Coast Avionics (which I got for < $300 at an airshow). My conclusions:
Bose: my top choice, much as I hate to admit it. Is it overpriced? Oh yeah. Can you get something else just as good for less? No.
Lightspeed: a close second to Bose. I'd say it's 85% as good for about 85% of the price.
David Clark: Quiet, comfy, and built better than the rest, but their tech is one step behind.
Gulf Coast: Not a bad deal if you only have $300 to spend. Buy one and use it while you save up for something better.
If the Chinese ever saw what Bose was getting for an A20, they would knock them off and be blowing them out for $200 ea. Lucky for Bose, the aviation headset market is too tiny for them to notice.
