I see that Quiet Ride sells a kit to retrofit your helmet with the inflatable earmuffs as well. I am due for a new crash hat, and have kinda decided on an RF-1200, on advice of my sister, who wears the same size as me, and says hers is MUCH more quiet than her old helmet ( Scorpion EXO 700, which I also wear now). The retrofit kit sounds like it might be an interesting project-I love to listen to music while riding, and this might make it easier. I currently wear Comply foam buds on my earbuds, which works pretty well, but these ( and a quieter helmet) might make it even better.
