Purchased on Amazon for 25,580 yen. Shokz OpenSwim Pro (Red) - New and unused. These bone conduction headphones are completely waterproof, offering high performance while seamlessly integrating into an active lifestyle. I excitedly bought them for exercise at a nearby sports club, but I've been too busy with work and daily life to use them, so they've been stored away. The Shokz OpenSwim Pro boasts three key features: "boosts motivation while swimming," "can be used during commutes," and "versatile bone conduction headphones for both everyday use and sports." Whether at the pool or the gym, it provides an unprecedented level of comfort for calls, music, podcasts, and any other scenario. Since they are new and unused, you can experience their quality right away. Main Specifications: • Waterproof Performance: IP68 equivalent, dustproof and waterproof design. Submersion in up to 2 meters of water for 2 hours is OK. • Two Audio Playback Modes: Streaming playback via Bluetooth 5.4, and a built-in 32GB MP3 player that can be used underwater. By directly saving music to the device, you can boost your motivation in the pool without locking your phone. • Storage Capacity: 32GB, capable of storing up to approximately 8,000 songs.
