I own a Bose and fly the RJ. As stated earlier, it's a bit of an overkill but still a great headset none the less. I never use the ANR function as it's quiet enough without it. I've never had a sore head due to the clamping effect most headsets give you.
The headset developed a few cracks on the earcup supports after 4 years. I called Bose who instructed me to send it in and they replaced the broken parts, gave me new ear seals and a head pad type thing, absolutely free of charge. I believe they come with a 5 year warranty.
Yes they do take up a little extra room in the flight kit but certainly don't add any weight.
I can't really comment on the Zulu headset other than I don't believe you'll be needing all the fancy gadgets you mentioned. Save that stuff for when the flights over with and you're away from the bird. I did however, have an F/O the other day who had just purchased a Telex pair (unknown model no.) and wasn't too impressed. He had trouble hearing me and ATC. It may have just been that he was used to his old David Clarks. He mentioned he would try using earplugs with them next time.

Are you at the bottom of someones seniority list?? If so, the Telex probably won't do you much good if you find yourself back behind the controls of a Prop.

So, IMO the Bose is a solid choice if you have the pesos. Great for most aircraft.
