1. Open-ear design
This design avoids the discomfort and potential hearing damage associated with traditional in-ear headphones. Additionally, since sound is transmitted through the skull, it reduces eardrum damage, enhances wearing comfort, and is suitable for sports, as it allows users to enjoy music while remaining aware of their surroundings.
2. Bone conduction technology
Utilizes true bone conduction technology, which uses high-frequency, low-density vibrations to produce pleasant sounds through the ear bones.These sounds are then directed into the ear canal via air, eliminating the discomfort associated with traditional earbuds and ensuring safer, healthier sound transmission.
3. Comfortable and breathable even after prolonged use
The ear-hook design ensures the headphones stay securely in place during intense physical activity, minimizing the risk of them falling off, and offering greater convenience, making them a reliable music companion for workouts.
4. Bluetooth 5.4 connectivity
Equipped with Bluetooth 5.4 technology, the earbuds offer stable and fast connections, efficient data transmission, smooth audio quality, and minimal disconnections or lag.
5. Ultra-long battery life
A single charge provides hours of use, eliminating the need for frequent recharging, and meets the demands of extended workouts, outdoor adventures, and other extended use scenarios.
