About This

• Open Ear Design for Outdoor Safety: Need to hear traffic and ambient sounds while running? These bone conduction headphones keep your ears completely open, so you never miss approaching cars, cyclists, or announcements. Unlike noise-isolating earbuds, they eliminate ear pressure and sweating—even during marathons or summer training. Best for: outdoor runners, cycling commuters, and anyone who refuses to choose between music and safety.
• Feather-Light Build with Secure Fit for All-Day Wear: At just 22 grams, these open ear headphones are barely noticeable after minutes of wear. The ultra-lightweight silicone frame and ergonomic wrap-around design stay firmly planted whether you're sprinting, doing box jumps, or on a 6-hour bike ride. No pressure points. No ear fatigue. Just stable, comfortable listening from your morning run to your evening commute.
• 15mm Dynamic Drivers with Balanced Sound for Workouts: Our advanced 15mm dynamic speakers and neodymium magnet drivers deliver clean, balanced audio with clear highs and natural mids. You'll hear every beat of your playlist and every word of your podcast—while still hearing the world around you. Not audiophile-grade sealed sound, but more than enough for great-sounding workouts.
• Magnetic Charging & 14-Hour Battery：The sealed magnetic charging port keeps moisture out—no exposed ports or rubber plugs to lose. Perfect for running headphones that face heavy sweat and light rain. With a low-consumption chip and high-capacity battery, enjoy 14 hours of continuous playback: 7 marathons or 3 workdays on one charge. Most competitors stop at 8 hours. We kept going.
• Built-in Mic & Bluetooth 5.4：The built-in mic is optimized for active use—clear enough for quick check-ins or coordinating with a running partner. No fake noise cancellation that distorts voices in wind or heavy breathing. Your voice stays natural, even when out of breath. Bluetooth 5.4 delivers instant pairing, stable signal, and multi-point connectivity between phone and laptop.
