Enhance your swim with underwater audio

The FINIS Duo blends rugged waterproof design with a listening experience that travels through bone conduction. As you push off the lane line, you can enjoy your music or tempo cues without adding bulk or cords from other devices. The result is a streamlined, pool-ready companion that stays with you through turns, drills, and steady sets.

Built for swimmers who want to stay in the rhythm of their workout, the Duo delivers sound through cheekbones, giving you a sense of immersion while still being aware of your surroundings in the water. This approach can help you maintain pace and focus across intervals, making training feel more purposeful rather than routine.
