New, Unopened / Free Shipping / Anonymous Delivery Available for Immediate Purchase 【Bone Conduction Technology × Open Design for Safety and Comfort】 Bone conduction headphones adopt an open structure that doesn't cover the ears. Because sound is transmitted directly to the inner ear through the bones, you can enjoy music while still clearly hearing ambient sounds (such as station announcements or bicycle bells while jogging). This prevents the "anxiety of not hearing surrounding sounds," which is common with conventional earphones, and enhances safety when outdoors. Since they don't block the ears, they are comfortable to wear for long periods without causing ear fatigue or a feeling of stuffiness. They are also perfect for those with sensitive ears or those who work from home and listen to music or make calls for extended periods. 【Bluetooth 5.4 Equipped × Stable Connection & High Sound Quality】 The latest Bluetooth 5.4 chip provides a stable connection over a wide range. Sound skipping and delays are significantly reduced. Whether you have Android or iPhone, the device automatically enters pairing mode when turned on, eliminating the need for any setup. No troublesome settings are required. In addition, it features dual microphones and noise-canceling functionality, enabling clear calls even in noisy environments. It's useful in a wide range of situations, from business meetings to conversations with friends. 【26g Ultra-Lightweight × IPX7 Waterproof, Perfect for Sports】 With a lightweight design of only 26g, the wearing experience is very natural. It doesn't put any strain on your neck or ears, even during running or cycling. The flexible neckband provides an excellent fit and stays in place even during vigorous movements. Furthermore, it is IPX7 waterproof, making it resistant to sweat and sudden rain, allowing for comfortable use in outdoor activities and sports at the gym. 【Up to 11 Hours of Playback × Type-C Fast Charging】 A full charge provides up to 11 hours of continuous playback. You can use it without charging for long periods, even when combining commuting, daytime music listening, and evening exercise. Charging is supported by the convenient USB Type-C and features fast charging. You can use your smartphone charger on the go and quickly replenish the battery. It's also convenient for business trips and travel.
