Love This Helmet Works Really Good In Any Riding Condition For MP3/GPS, Very Loud At Any Speeds Ive Been Up To 100mph Blutooth Phone Works Good Also Just Close Vents So Your Heard Better Up To 70mph?? Connects To Other O'Neal Helm For Easy 2Way Which Ive Used Also And Works Good @ Slow Speeds 40mph Or Less Gets Really Distorted When Riding Over That. Only Peeve I Have Is When Taking Calls With My iPhone4 & Going Back To MP3 Listening Mode The Music Starts Chopping Up Like Scratched CD?? Something In The Call Disrupts Blutooth Connect?? I Just Shut Off Helm & Cut Back On & Reconnect Then It Works Great Again!!
Got this helmet because it had the Bluetooth and it’s the smartest thing I have done. I use the FM radio all the time plus it is really convenient to be able to take calls if I need to. Also it is lightweight, fits really well, and doesn’t fog up. Great buy!
