The Open-Ear Sound technology provides a natural sound experience with minimal sound leakage. Thanks to this innovation, sound pressure is directed towards your ears through waves, while a compensating signal reduces sound dispersion. You can enjoy your sound while keeping your privacy protected. The headphones do not block your ear canal, allowing you to comfortably hear both your sound and the world around you. This makes them perfect for outdoor sports activities. The headphones are IPX5 water and sweat resistant and connect via Bluetooth 5.3 to your smartphone.
