🎊◆Introducing the latest evolved neckband earphones with adjustable cords and 40 hours of continuous playback◆🎊 🌈【Cutting-edge Bluetooth 5.3 chip & large capacity】We have researched the use of neckband earphones and are now offering the latest neckband earphones with adjustable cords! Adopting cutting-edge Bluetooth 5.3 technology, it offers excellent and stable connectivity, improved communication speed, and communication range. Compared to conventional products, this device offers improved performance even during high-speed travel and in long-distance environments, reducing issues such as sound skipping and interruptions. Equipped with a high-capacity, energy-saving battery, it boasts the longest usage time in the industry, offering up to 40 hours of use on a single full charge! This is more than double the usage time of ordinary Bluetooth earphones. USB Type-C charging enables fast charging; just 10 minutes of charging provides approximately 2 hours of use! Recommended for those who frequently travel long distances, such as students, runners, travelers, and business travelers. (Note: Playback time may vary depending on charging time, volume settings, content played, usage environment, personal usage habits, and connected devices.) 🎵【Adjustable Cord Length Neckband, Newly Designed Convex Buttons, Excellent Fit】Unlike conventional neckband earphones, we've added an adjustable ring to prevent cord tangles. If the cord becomes a problem during use, you can easily adjust it to the appropriate length. The earphones also feature convex buttons, making them easy to identify by touch and allowing you to operate them without looking! Made with environmentally friendly rubber, they are gentle on the skin and more comfortable to wear around the neck. Furthermore, since ear shapes vary from person to person, the fit of the eartips is also important. Therefore, four sets of replacement eartips (S, M, L, M') are included so you can choose the appropriate size. To reduce pressure, the main unit is lightweight at approximately 33g, making it gentle on the neck. Recommended because the cord won't get in the way! ⚡【Hi-Fi High-Quality Sound, 9D Stereo Sound, CVC 8.0 Noise Cancellation】Equipped with a composite eardrum dynamic driver, and supporting AAC and SBC codecs, these high-quality codecs compress audio data when transmitting music from audio equipment to earphones, enabling immersive 9D stereo sound like a concert, with low latency and high sound quality. Furthermore, CVC 8.0 noise cancellation technology provides excellent sound isolation, moderately cutting out ambient noise, supporting clear music listening and calls even in noisy places such as shopping districts, train stations, airplanes, and trains, without being affected by surrounding environmental noise. The earphones also have a built-in directional microphone that cuts out ambient noise, supporting hands-free and clear calls. 🎶【Automatic Pairing & Multipoint Support】When using the neckband earphones for the first time, simply turn them on and they will automatically enter pairing mode. Select "B09" from your device's Bluetooth settings screen to connect. Once connected, subsequent uses will automatically connect to your device simply by turning on the earphones. With wide compatibility, they can pair with commercially available Bluetooth devices. Furthermore, they feature multipoint pairing, allowing simultaneous connection to up to two Bluetooth devices. This is extremely convenient for those who own multiple smartphones or tablets! ✨【Waterproof, Magnetic, Easy One-Hand Operation for Beginners】Our Bluetooth earphones are waterproof and sweatproof, making them suitable for listening to music while sweating during sports like running or going to the gym, in the humidity of a bathroom, or in light rain during workouts. They also reduce the risk of damage if you get caught in a sudden downpour while running. The magnetic design allows you to hang the earphones around your neck when not in use, preventing loss. The controller unit has four function buttons: power button, volume up button, multifunction button, and volume down button. The multifunction key allows for easy hands-free calling, volume adjustment, and track skipping/rewinding.
