Hey guys...if nobody has tried this with the stock HD headset, give it a shot, it works. Get some foam rubber, like an old cushion or pillow and cut some foam to fit in the ear hole of your helmet. Cut out an opening for the speaker to set into. This takes a little trial & error to get it perfectly lined up with your ear canal opening for the best sound. Cover it with black cloth and glue it (I use 3M adhesive...or set it in loosely, but you'll be cussing that after it falls out a few times) into the ear opening on your helmet. It holds the speaker next to your ear (how tightly depends on how much foam you use) and you can hear the OEM headset soooo much better. Even the bluetooth cellphone module is understandable at speed now. It also quiets the outside noise and completely eliminates the wind noise.
