We've got the Bose in one of our C-90s, and it works really, really well. It's light, and very comfortable, but you're screwed if the batteries die on ya...there isn't much passive reduction to speak of.
I'd been researching ANR headsets for myself recently, and, after reading a LOT of positive reviews, I ordered a Lightspeed Zulu, which should be here in a day or two...it's sitting in OKC right now...damn you, UPS Ground! Get moving!!

I hear it's rated right up there with the Bose for reduction and comfort, but is also about $150 less and has a 10 yr warranty. The only downside I read is that Lightspeeds, in general, seem to break easily. I'm hoping that since this is a new model, and that enough time has passed since it debuted, that they've got the Qual Control problems worked out. Either way, at least it has that warranty!
I'll get you a review as soon as I can, if you'd like.
