The Outdoor Tech X Giro Chips 2.0 Wireless Bluetooth Helmet Audio fuels progression sessions in the park and powder slashes in the trees with high-fidelity 40mm drivers pumping face-melting guitar solos and inspiring instrumentals straight to your helmet's liner. Audio streaming with Bluetooth devices eliminates annoying wires for good. For riders always on the grind, the Chips 2.0 feature one-tap answering and voice activation, so you'll never have to remove gloves for taking and making calls. New for this season, the Chips 2.0 feature a Walkie-Talkie function that sends audio messages to other riders rocking Chips 2.0 on the mountain, meaning you'll never lose your friends to blizzards or confusing terrain. To use the Walkie-Talkie function, you'll have to download Outdoor Tech's Walkie-Talkie app, then set-up a group of messengers you'd like to communicate with on the mountain. There's no range limit for sending audio messages, making it ideal for staying in touch with your riding party across wide swaths of alpine terrain. These wireless audio speakers work with compatible ski/snowboard helmets, dropping into the helmet's liner for a seamless listening experience without lugging around bulky headphones. Currently, they're compatible with certain helmets from the following manufacturers: Bern, Anon, Giro, Smith, POC, Pro-Tec, Solomon, and Bollé. Outdoor Tech also makes a compatible K-Roo Pouch (not included) for using the Chips 2.0 speakers with regular skate, snow, and BMX helmets.
