【Bone Conduction Technology × Open Design: Safety and Comfort Combined】 Bone conduction headphones adopt an open design that doesn't block the ears. By delivering sound 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" that often occurs with traditional earphones, enhancing safety when outdoors. Because they don't block the ears, they are comfortable to wear for extended periods without causing ear fatigue or a feeling of stuffiness. They are perfect for those with sensitive ears or those who work from home and listen to music or make calls for long hours. 【Bluetooth 5.4 Equipped × Stable Connection & High Sound Quality】 The latest Bluetooth 5.4 chip provides a stable connection over a wide range. It significantly reduces sound skipping and delays. Whether you use Android or iPhone, the device automatically enters pairing mode when turned on, eliminating the need for any setup. No troublesome settings are required. Furthermore, it features dual microphones and noise-canceling functionality, enabling clear calls even in noisy environments. From business meetings to conversations with friends, it excels in a wide range of scenarios. 【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 your commute, 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 worry-free for business trips and travel. 【Easy Operation × User-Friendly Design & Reliable Support】 The main unit features a simple one-button operation. You can intuitively control music playback, pause, skip forward/backward, adjust volume, and answer calls.
