Featuring cutting-edge Bluetooth 5.3 technology, these earphones offer excellent connectivity, stability, and improved communication speed and range. Compared to conventional earphones, these headphones offer improved sound quality, even when traveling at high speeds or over long distances, reducing skipping and cutting out. Their high-capacity energy-saving design offers the industry's longest battery life, reaching 40 hours on a single charge! That's more than double the life of standard Bluetooth earphones. USB Type-C charging allows for fast charging; just 10 minutes of charging will give you about 2 hours of use! They're perfect for those who travel frequently, whether commuting, running, traveling, or on business trips. (Note: Playback time may vary depending on charging time, volume adjustment, playback content, usage environment, personal usage habits, connected device, etc.) 🎵 [Adjustable Neckband, Newly Designed Convex Button, and Excellent Fit] To avoid the hassle of traditional neckband earphones, we've added a ring to adjust the earphone length. If you experience any issues with the earphone cord during use, you can adjust it to the appropriate length. The earphones also feature a convex button, which allows you to easily locate the button with your fingers and operate the earphones without looking! Made with environmentally friendly rubber, it's gentle on the skin and makes wearing them around the neck more comfortable. Furthermore, since ear shapes vary, the comfort of the earbuds is also important. Therefore, four sets of replacement earbuds (S, M, L, M') are included, so you can choose the size that best suits you. To reduce pressure, the earbuds weigh approximately 33g, making them comfortable around the neck. We recommend them because the cord doesn't get in the way! ⚡ [High-Fidelity Sound, 9D Stereo Sound, CVC 8.0 Noise Cancelling] Equipped with a composite dynamic driver, these earbuds support both AAC and SBC codecs. AAC is a high-quality codec used to transmit music from your audio device to your earphones and compress audio data. This allows for low-latency, high-quality sound in immersive 9D stereo, like a concert. CVC 8.0 noise cancelling technology also provides excellent sound insulation and reduces background noise, allowing for clear music listening and calls without being affected by ambient noise, even in noisy places like busy streets, train stations, airplanes, and trains. The earbuds also feature a built-in directional microphone, which filters out ambient noise and allows for clear, hands-free calls. 🎶 [Automatic Pairing and Multipoint Support] When using these neckband earphones for the first time, simply power them on and they will automatically enter pairing mode. Select "B09" from your device's Bluetooth settings screen to connect. Once connected, they will automatically connect to your device the next time you power them on. Wide compatibility allows you to pair with commercially available Bluetooth devices. Furthermore, the multipoint pairing function allows you to connect up to two Bluetooth devices simultaneously. This is extremely convenient for those who have multiple smartphones or tablets! ✨【Waterproof, Equipped with a Magnet, and Easy One-Hand Operation for Beginners】Our Bluetooth earphones are waterproof and sweatproof, making them ideal for listening to music even during sweaty workouts, running, or at the gym, or even in light rain. Even if you get caught in a sudden rain shower while running, the risk of damage is reduced. The magnetic closure allows you to hang the earphones around your neck when not in use, helping to prevent them from getting lost. The controller unit has four function buttons: power, volume +, multi-function, and volume -. The multi-function key allows for hands-free calling, volume adjustment, and track skip/rewind operations. Additionally, you can activate Siri (voice assistant) by pressing the power button once after turning on the earphones.
