Shokz OpenSwim Pro S820-ST-SR-US-326
DualPitch technology combines bone conduction for mids and highs with air conduction for deep bass, creating a more complete open-ear soundscape than standard sports headphones. The unibody frame with Ni-Ti alloy memory wire delivers a secure, low-clamp fit with a 16% reduction in clamping force, while IP55 water resistance handles rain and sweat. These are best for runners and cyclists who need 9-hour battery life and full environmental awareness during outdoor training.
