Check these out guys. I've got these headsets that use a military technology that completely eliminates wind and background noise while you're riding. I tested it on a ride to Whistler about a month ago and you can completely have a conversation while riding at any speed with as much exhaust and road noise as possible. It's a thin band that wraps around your neck and feeds off the vibration from your voice box instead of a hanging microphone. They are available for pretty much all types of cel. phones.
