I have had Arais for about 15 years or so and have always worn earplugs or headphones but they can still be a bit noisy. This summer I bought a REVUU (with the rear view mirror in it), it more comfortable and much quieter than my Arai and the vents seems to work better too. I found the buffeting much less (helping the lower noise?) and the rear view mirror is an excellent idea (takes 500-600 miles to get used too).
Downsides are, its a bit heavier than my Arai (about 300 grams), the shell is a bit bigger so can now only fit the one helmet in the top box and the lining is a little light in colour so shows dirt easier. That said it comes out easily for washing.
I got mine from Shineybikesyndome (Nooj on here), well worth a punt.
