VeloVox allows for hands-free group communication with up to 30 participants, listening to music, and receiving calls. Since the ears remain uncovered, wearing comfort is very high, and you can still be aware of your surroundings. Thanks to wind and noise cancellation, VeloVox offers very good sound quality. The two units, each weighing only 19 g, are compatible with most helmets and fit securely and discreetly on the left and right of the helmet strap. VeloVox connects via Bluetooth to your smartphone and communicates through mobile networks with other group members. To keep your hands on the handlebars, VeloVox enables connectivity with Shimano Di2 and Shimano E-BIKE SYSTEMS. With a simple press of a button, you can control communication, music, and phone calls.
