Hi mate
The DCs are the Lycoming/Bell 47 of headsets. Good in its day, still reliable, in any other industry they wouldn’t sell a single pair!
I can’t remember the model number, but I’d tend towards the “helicopter” model that advertises "high passive protection". I’d also look at one that has an easily swappable mic (one screw to remove, two for the electrical connections). Many models (and brands) don’t offer different mics and in the helicopter world it can be important, as there are 2 completely different impedances used, plus some primitive ICS are sensitive to even the diff between electret and dynamic mics.
I used to have a set of DCs with several mics and a small screw driver.
There is a model with switchable impedance. I haven’t used it, and understand its pricey, worth investigating though.
I have just bought a Lightspeed Zulu ANR.

I’ve only used it once. It’s great, and the Bluetooth phone connection works very well. I can’t use it in a Puma, and don’t know if different impedance mics are even available. Of course in my usual over the top approach I also use two helmets, one high

, one low impedance

. (one with ANR, both dual visor

)
