Of course fit and function are very personal but after 20 years of bone domes with noise, weight and fit issues I have found the best for me.
Gallet LH 250 from Merit Apparel in Florida (excellent service)
Merit Apparel
with a Bose ANC (Active Noise Canceling) headset
Bose Aviation Headset X - Pilot Headsets - Bose Headsets and Headphones
installed by the magical engineer who keeps me airborne. Quiet(er) and more comfortable than anything else I have tried.
On the minus side - cost, possible loss of warranty, you (or someone else) have to build it yourself, takes two AA batteries for 40 hours (but it will turn itself off if unused for a bit).
On the plus side - Best ANC of the 4 that I have used, Superb audio (I can understand the high pitch low volume conversations that were lost before), soft ear seals (won't turn rock solid in cold weather like Oregon Aero's very good ones), the headset disassembles and installs without wrecking anything (i.e. both helmet and headset can be put back together as original if need be).
This is THE helmet of the 21st century.
PM me if you want more info.
