I don't think another helmet would do much to reduce the wind noise since its the straps that are creating the deflection. Maybe try putting your sunglasses over the helmet straps to keep them pressed closer to your head and out of the wind. You could try any type of earplug or earbuds without the music, but it will cut down your ability to hear traffic along with cutting the wind noise. The wind noise has never bothered me enough to buy any of the products mentioned.
