the wind shield youre talkn about is by clarks custom flht windshields ,,they are 7" wider than stock and they do allow more sound to get to your ears... another name for um is halfmoon shields
That's what I have on mine. The design gives you more sound, and keeps more wind off your hands. Unique, not seen anybody around here with one on their bike, and it cleans up good and is still in like new condition after 6,000 miles. They cut size to order, and will even do custom sizes and tints that aren't on their site...just send them an email with what you are looking for, and they will send a quote.
They also send a handwritten note of thanks with their packages, and always nice on a phone.
I purchased a klock werks & rode with it for 150 miles switched to the clark custom and much better sound less bugs on the helmet... A win, win, & a hell of a lot cheaper. And Yes they do send a personal thank you with the windshield.
