Are you planning on flying as a private pilot?
The best advice given to me when buying a headset, as a private pilot, was to buy a cheap first pair. Eventually, you'll buy a second one, which will be a better one, and will relegate your first one as occasional use for your passengers. This also gives yourself time to figure out what you really want.
Other than that, I'd say buy a passive set from David Clark. Reasonable prices. If you're looking at long term, frequent use, ANR is a big plus. Just make sure it'll continue to operate as a passive set if the battery gives up.
