I'll give the old school dissenting opinion.
I've used a Zulu 3 and it was nice enough. However, I ultimately opted to refurbish my David Clark H10-40 headset and buy another one already refurbished.
They were cutting edge 1980s technology and were cataloged until the mid to late 1990s if I recall correctly. They are old, but they still work really well, are basically bullet proof, and there are a ton of David Clark and third party upgrades out there that let you customize them to your preference. For a new or part time pilot they are also a very affordable route to take.
My H10-40 was 30 years old and the foam was crumbly, so it needed new foam in the ear domes. A complete replacement set from David Clark (DC) was $18. I also replaced the gel ear seals and I upgraded to a gel head pad, although I used a non DC model that I liked a lot better than the DC head pad options.
I put $60 into refurbishing it to regain the full passive noise protection and functionality, with the improved comfort of a gel head pad. For me it made sense as I owned it, liked it and found it to be very comfortable on long flights with the gel ear seals and even more so with the gel head pad. No hot spots at all.
If you don't have one sitting around you can do what I did for a second head set and buy a refurbished H10-40 for around $200. You can find them non refurbished on E-bay for around $100. Just be aware you'll probably need to replace the ear seals and the ear foam - about $45 total.
I also bought a third H10-40 off E-bay for $100 to put in a leather flying helmet and it unfortunately had a com cord that failed the wiggle test. The major expense was replacing a com cord on one of them that failed the wiggle test. That was a $70 part and took about 30 minutes to replace. (Soldering is required, so if you are not fairly good at soldering you'd need to pay an avionics shop to replace it.)
Cords rarely go bad but it's a $70 hit if they do, so buying one refurbed from an avionics vendor like KC Headsets might be a little cheaper in the end, or at least no risk.

In terms of ANR, you can also upgrade any of the David Clark H10-XX headsets to ANR for $200 with the ANR conversion kit from Active Headsets:

If you are not into doing your own solder connections, Active Headsets will do the conversion for you for another $50. That conversion also solves any broken com cord issues as it replaces the old cord.
So for $200 you can get a very well made and durable refurbished H10-40 headset. Alternatively, for $400 to $450 you can get excellent hybrid passive/active noise reduction in a quality refurbushed H10-40 headset that will literally last you your entire career. The ANR conversion adds an additional 18 dB to 21 dB of noise reduction between 80 and 500 Hz on top of the passive 14.7 dB to 36.1 dB reduction you get from 25 Hz and 8,000 Hz with the David Clark H10-XX series headsets. That's only about $100 more in total than you'd pay for a new H13.4 passive headset from David Clark.
Interestingly enough, you can also buy a remanufactured H13.4 with the Headsets Inc. ANR system installed for $499 with a 2 year warranty.

Something else to consider is that a hybrid passive/active unit still retains it's passive performance if the ANR electronics fail, or the batteries go dead. It'll also work in any aircraft, unlike an ANR headset designed for panel supplied power.
