(Note: Playback time may vary depending on charging time, volume adjustment, playback content, usage environment, personal usage habits, connected devices, etc.) [Silicone Neckband, Excellent Fit, and Equipped with Magnets] Neckband earphones come into contact with your body frequently, so comfort is key. Our neckband is made of soft silicone for a comfortable fit with minimal pressure around the neck. Its design resists deformation and prevents earbuds from falling out, even when worn for long periods of time or while running. Furthermore, ear shapes vary, so earbud comfort is also important. Four sets of replacement earbuds (S, M, L, M') are included, so you can select the appropriate size. To reduce pressure, the earbuds weigh approximately 33g, making them gentle on the neck. The built-in magnets allow you to hang the earphones around your neck even when not in use, helping to prevent them from getting lost. We recommend this product because it keeps the cord out of 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 and 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 surrounding 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 to automatically enter pairing mode. Select [H39] from your device's Bluetooth settings screen to connect. Once connected, the earphones 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, 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! [IPX7 Waterproof & Easy One-Hand Operation Even for Beginners] Our Bluetooth earphones are IPX7 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 controller unit features four function buttons: power, volume +, multi-function, and volume -. The multi-function keys allow 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.
