Toggle between these audio options and customize your EQ settings with the intuitive Shokz App. The Shokz signature open-ear design provides enhanced comfort and safety as it keeps your ears bud-free and you fully aware of your surroundings through any adventure. OpenSwim Pro is further engineered for your active lifestyle with an ergonomic design, secure fit, and sports-optimized control buttons. Power through extended listening sessions with up to nine hours of continuous battery life, plus a 10-minute quick charge to immediately prepare for up to 3 hours of listening time.
