Rode in to work today, 1 hour on the interstate I84 to I684. Wind was brutal.
Anyway, I notice my helmet (HJC CL-SP) is way noisy when leaning forward at higher speeds. If I sit up higher and hold my head up and back, the way I would be sitting on a cruiser the wind is more tolorable. But at 60-65mph and up, if I lean in a bit over the handlebars, it gets so loud, and the helmet start to rattle around like a bobblehead.
Gonna start using earplugs for the commute.
 

I know a lot of guys who wear earplugs on the highway.  I'm in the market for a new helmet too and the Scorpion EXO 400 has great reviews...it is supposed to be pretty quiet.  I would also make sure that you helmet fits correctly too.  Maybe it is too loose in the cheeck pads and allowing wind up to your ears.  I don't know...

Rattles? I had a cheap helmet that I borrowed from my friend a couple of months back and it was the bottle neck while traveling on the highways. At any speeds over 55 mph it would start to rattle and It was so damn uncomfortable. Had neck pains then!  If I turned my head to check my blind spot, it would be a big deal to turn my head back straight. 

I upgraded to a shoei helmet. Got a good deal of a used one on craigslist. It is a real pleasure now. No problems even at 85 mph. Good circulation, great fit and comfort.  to shoei.

Anything over 60 and i'm fighting the wind all the way.
If I turn my head, feels like my head will snap off my neck.

I have a KBC TK-7 and the wind noise gets to me too.  If I shrug my shoulders while riding, the noise disappears completely though.  When I'm riding around 80mph, the helmet slips back on my head allowing my nose to touch the inside of the front.  I probably need a new one as well.

I have the noise issue but my helmet is tight on my head.When I turn my head it to feels like my head is coming off.I like modular helmets with the flip up face and inner day time shield.Anyone have experience with these types of helmets.I think the helmet I was looking at was HJC.

I recently bought an HJC AC-12 and it is somewhat noisy, not too bad though. At the same time I bought my girlfriend a GMAXX GM68S and it seems to be an awesome helmet, I recommend it.

I have a Suomy, a Shoei and a KBC, and the best helmet and tightest (Suomy) is the loudest. The quietest is the KBC, but since I hit the ground in it, and took out a quarter size piece, I can't use it for anything where quiet matters. I think that it has something to do with head fit. I will say that if your helmet moves when you are riding, it seems too loose.

Are you sure this helmet is still safe to use?! 

im a big fan of the scorpion line of helmets.  they are sweet

I have a Caberg Trip Double Visor flip-up helmet, below. I liked the idea of being able to have it open face, but in practice I still feel like I should take it off when paying for petrol, and it's not great for riding open-face as the extra wind resistance makes you feel very unbalanced above 40 mph. However, you CAN remove the front visor section completely which would resolve this issue.

It's fine up to about 65. Beyond that there is *some* noise and drag if you turn your head, but I'm pretty comfortable with that after a few months' use. It's a little loose; if I had the right size I'm sure these issues would be much resolved. Recommended if you can find somewhere to try it on first. Quite a practical choice, but it's certainly not as sturdily constructed as a bona fide full-face helmet.

Your helmet should be snug to your cheeks.  Keep the strap snug, high speeds will lift many helmets up and be uncomfortable if not restrained. 
Noise, I have yet to find a really quiet helmet for the highway. 

Big issues
Removable liners and cheek pieces you can wash by hand.
Space enough to put on glasses if you wear them or use sunglasses behind the visor.

Cycle gear has a real nice return policy I hear.  Try a couple.
I did test fit a Scorpion EXO 700 and it was an excellent fit with plenty of ear space, nice vent layout and decent price.

One thing to watch is if you can pop the visor open for extra air without it being unbearably loud or whistling.

Shark RSF 2i is my helmet of choice right now.
Cheap, AFX, FX-10, not bad overall.
tough=Simpson, louder than hell.

I love my Scorpion EXO700..it's fiberglass and kevlar laminate.Vents good and sheild removal is a snap.Very cool looks.

just go with an ARAI. best money you will ever spend.

It is not, but I like it and use it for dual sporting, which for me is 90% 1st and 2nd gear.

Helmets break in. If you sweat a lot, the acids are supposed to really break down the material. I guarantee you that a year old Large will be looser than a new Extra Large.

Another vote for the Scorpion!   

Just don't buy a Shell helmet. My visor flips up at high speed when I turn my head 

I have a Scorpion EXO 400, and a EXO 700, I also own a Vega Altura. I would have to say my Scorps are the most quiet, but the Vega has better ventilation. Are you riding a F model? If you are try a different windscreen, I think someone makes a touring windscreen which directs the air over the helmet, I have a F model with the stock screen and the windblast seems to hit right at the base of the helmet,

Because everyones head is different like a finger print so is helmet selection.  I love the Shoei and the HJC but in saying this the HJC fits my head better than the Shoei hence the reason why I own 2 HJC's.

Try on several different helmets to find a good cumfy fit.  Don't buy that 600 dollar shoei just because your mates say that it is cool to own a shoei when it feels like crap on your head.

I have never been one for ear plugs as you want to hear the engine talk to you as well as listen out for car noises horns etc.  If you have to wear ear plugs select a 20db plug instead of a 70db or 90db block plug.
