🎊◆Introducing the latest evolution of neckband earphones with adjustable cords and 40 hours of continuous playback◆🎊 🌈[Cutting-edge Bluetooth 5.3 chip & large-capacity battery] We've researched the use of neckband earphones and are introducing the latest neckband earphones with adjustable cords! Featuring cutting-edge Bluetooth 5.3 technology, these earphones offer excellent connectivity, stability, and improved communication speed and range. Compared to conventional earphones, these earphones offer improved sound quality, even when traveling at high speeds or over long distances, eliminating skips and dropouts. The energy-saving, high-capacity battery delivers 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 provides approximately 2 hours of use! This earphone is recommended for those who travel frequently for long periods of time, such as commuting, running, traveling, or business trips. (Note: Playback time may vary depending on charging time, volume adjustment, playback content, usage environment, personal usage habits, connected devices, etc.) 🎵 [Adjustable Neckband with Convex Button Design for a Comfortable Fit] To avoid the hassle of traditional neckband earphones, we've added a ring to adjust the earphone cord. If you experience any cord issues during use, you can adjust the cord to the appropriate length. The earphones also feature convex buttons that are easily accessible with your fingers, allowing you to operate the earphones without looking! Made with environmentally friendly rubber, these headphones are gentle on the skin and comfortable to wear around the neck. Furthermore, ear shapes vary from person to person, so the comfort of the earbuds is also important. Therefore, four sets of replacement earbuds (S, M, L, M') are included, so you can select the appropriate size. To reduce pressure, the headphones are lightweight, weighing approximately 33g, making them gentle on the neck. We recommend them because the cord doesn't get in the way! ⚡ [Hi-Fi High-Quality Sound, 9D Stereo Sound, CVC 8.0 Noise Cancelling] Equipped with a composite tympanic dynamic driver, they also support AAC and SBC codecs. A codec is a high-quality codec used to transmit music from an audio device to the earphones and compress audio data. This allows for immersive 9D stereo sound with low latency and high sound quality, like a concert. CVC is also supported. 8.0 noise canceling technology provides excellent sound insulation and moderate ambient noise reduction, allowing you to enjoy clear music listening and calls without being affected by surrounding noise, even in noisy places like busy streets, train stations, airplanes, and trains. The earphones also feature a built-in directional microphone to reduce ambient noise and support clear, hands-free calls. 🎶 [Automatic Pairing and Multipoint Support] When using these neckband earphones for the first time, simply power them on to 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 second time you power them on. Wide compatibility allows you to pair with commercially available Bluetooth devices. Furthermore, multipoint pairing allows you to connect up to two Bluetooth devices simultaneously, making them extremely convenient for those with 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.
