I have a rf-1100



Very comfortable but I do find it a bit loud at times. I don't really notice any wind buffet until I hit speeds I'm not allowed to post.

 

No helmet is really going to be the same for everyone. Different head shapes allow for different amount of wind getting in, which means more sound. I have a Shoei TZ-R. Its similar to the RF series, just less venting. It has been discontinued, but I picked it up brand new for under $200, and for a Shoei, thats pretty good imo. It's pretty quiet. On long rides I wear earplugs, mostly because my shorty is so damn loud.

Honestly, I have looked at other helmets from ICON, HJC, Arai, Suomi, and Scorpion, but I just am too happy with the Shoei to make a switch.

 

I have a Rocket Prime (made by HJC) and will second the earlier comments about HJC. Good: great fit and comfort, good venting, not much buffeting. The Bad: Very loud, both at low speed and high.

 

I can highly recommend the Schuberth C3. I've had mine for nearly a year now.
When I got it (bright fluro yellow) I felt as though I'd always had it. Great fit and comfort.
The manufacturers say it's quiet. It is.
Absolutely no problem with aerodynamics. Your head goes where you want it to even at high speed out of the bubble.
Visor and sun visor are really good quality. Air flow is almost too much if you don't adjust the face and head vents. Visor stays where you put it and never flops down under pressure.
All round a good investment with the advantage of flip up and excellent neck protection from the elements. If you really have some dough to burn you can get a bluetooth built in but I've fixed my Scala to mine which works fine though you have to stick it on as the skirts around the bottom edge won't allow the clip-on arrangement.
No complaints. Drivers really notice the colour in their mirrors too.
Expensive... is the only downside.

 

I think for quiet helmets you will want one that markets as a touring helmet. I also think earplugs are the only real option for long distance travel, to block out the fatigue inducing white noise, wind buffeting the helmet

 

As explained to me, rhe higher the helmer becomes in technicality the less concerned the manufacturer becomes in comfort. Race helmets becomes less concerned about noise ans such. And become more xonxerned about slipstream and suxh

 

And I've been drinking so ignore the mispells

 

Must admit I was a bit skeptical on the low price but I gotta tell you my Scorpion (forget the model #) is the most comfortable and quietest helmet I've ever owned.

 

A lot of the comfort comes down to the weight of the material used to construct the helmet, by far carbon fiber are the lightest but the most expensive. More sound proofing adds more weight

 

I would honestly find a helmet that fits your head and is comfortable. Wear it in the store for 30 mins or so and see how it feels. Earplugs can always be added for the level of quiet you want. I love riding with plugs in. It decreases my stress levels dramatically.
