The Chips are Bluetooth speakers that fit inside your snow helmet. A rechargeable battery gives you 10 hours of playtime. Listen to music, podcasts, or make phone calls while on the mountain or sitting on the lift. Your ski helmet or snowboard helmet will never be the same after you get the Chips wireless speakers for snow helmet audio. No wires, no need to take off your gloves and you can leave your phone in your pocket. Works with nearly any audio compatible snow helmet, the Chips stream music from your Bluetooth audio device, completely wirelessly. Each earpiece features a single oversized button that you can operate easily with your mittens still on. Simple button press combinations let you control every feature without ever removing your device from your pocket. The Bluetooth connection, built-in microphone, and simple button interface of the Chips mean you can answer your next call without removing your helmet or gloves. No more fishing in your pants or pulling off your lid to tell your Ma you 'll be home in time for dinner. Just make sure you hang up before you start hassling ski patrol or debating skate laws with the police.
