LS2 FF800 - Wind Noise

I've recently purchased a LS2 FF800 Storm 2. I had tried it on in the showroom multiple times, and it was a very snug fit as recommended.I've recently purchased a LS2 FF800 Storm 2. I had tried it on in the showroom multiple times, and it was a very snug fit as recommended.
But once i cross the speed of 40-50, it feels as if air is getting trapped near the ears and its a very uneasy sound.
How do I fix this ? I've tried this using a balaclava, and closing all the air vents, but still no luck.
Any suggestions will be greatly appreciated
