Hey guys. So I have an HBC200 Force and it works great except for the intercom feature. I can hear music pretty well to a point, but I'll try to talk to my dad who has the same intercom and he can hear me just fine but I can't hear him over 20mph. He has an HJC CLmax II and I have a Bell Vortex. Could the wind noise in his helmet drown out the sound of his voice? I have a chin flap or whatever that piece of fabric is that covers the bottom of your chin, but I've still got pretty bad wind noise. However, the wind noise in his is mostly up front, where his mouth is. Could the helmets be the problem? Or part of them?
