I believe that I am qualified to answer your question:
Trike flying
Firstly do you fly with or without a helmet ? If flying with just goggles and a headset then their is very little available on the market that will suit both environments. Suggest that you dont go any further and buy a pair for each environment. Open cockpit is a totally different ball game and requires to be effective a combo of noise canceling, frequency filtering, correct mic shields, both in design and integrity. We think that we have almost cracked it after 4 years efforts..The same headsets due to the fact that the wind is basically a vortex amplifier dont perform in a closed cockpit so well.
Closed cockpits and helmets
Another ball game, but here depending on the visor and whether it has a bib, exposed to side wind ingress, and many other features of the user, it can work. Whatever you do, dont block the front of the mic shield as the ambient noise is needed to cancel the voice side.
Once again, depending on the intercom, radio and other various factors you will need a microphone amplifier, this is normally in the headsets. ideally adjustable.
I attach a picture of the injection moulding and the mic element that free floats in our own design boom, this performs very well.
ANR
Another minefield, ANR functions at low frequencies really well, screaming two strokes, thats another story. I have perfected a system which we use in Mil applications, in a trike, plain pathetic, even gel seals, we are using leather nappa now as a slightly improved seal. Our new range that we are tooling for at present and being launched at the Splash show in the UK end November may fit both installations...but no guarantee.
I like the Sennheisers as the seals are very comfortable, brand names be warned, they are just names...best buy two systems at present.
Good Luck

- The elements are noise canceling, the rules are simple dont attach them to anything !
