Haven't tried the actual Bluetooth helmets but I do use a scala rider g9x on my shoei RF-1200. It functions as rider to rider com, music from phone, Siri control, and am/fm radio along with a few other features like being able to connect up to eight riders at once. It's a little pricey ($300) but I would say it was worth it. Especially if you go riding with someone else who has one.
