Avoid the Lightspeed PFX. The battery life is terrible (5 hours or less) and the battery box is huge. I ended up selling mine on eBay.
I have a new Bose which I really like, both fixed wing and heli.
ANR is absolutely worth having, and the price difference between the various ANR headsets isn't really worth making a bad choice over.
My wife, who is an occasional passenger, has the Clarity Aloft in-ear headset and loves it. I also heard it strongly recommended by a guy whose day job is (believe it or not) flying a B17.
