Good advice.
I'm paying the price now at (nearly) 39 for many years of motorcycling, many years of playing in VERY loud rock bands, and a genetic pre-disposition to deafness.
At least 40db loss in most frequencies, but especially at the range in which women and children speak (apparently its a disability

)
So noise reduction is important ...
But so is comfort.
I have a Nitro N-500V.
It's not that expensive, about $300-ish.
The wind noise on my FZR750R was almost nothing, but on my RF900R it's more noticeable.
I'd recommend the Nitros - they seem to be a good helmet, but others will insist nothing less than a Shoei or Arai will do.
Try a few out ...
but please don't buy a second hand one of Trademe to save money - you may live to regret it (literally).
