Bluetooth Everywhere

Last year, I wondered, “Where is the [ski] helmet with the built-in bluetooth mobile phone headset?”
This year, victory is mine. Two companies offer ski helmets with Bluetooth connectivity: Marker with the M3 Audiorama and R.E.D. with the Tantrum Audex. At around $250, neither is a bargain. The Bluetooth feature comes at a $100-$150 premium over comparable helmets, including helmets with built-in wired headphones.
