Edifier R1 Open-Ear Earphones, Bluetooth 5.4, Ultra-Lightweight (5.8g), Wireless Earbuds with ENC Noise Cancellation, No Ear Blocking, Built-in

[Clear Voice Calls & Bass Boost] The R1 employs ENC call noise cancellation technology to fuse, compare, and separate information from different channels, enhancing the target voice and suppressing noise. It features a large-diameter 12mm driver with a titanium-coated diaphragm, delivering clear stereo sound. The directional sound distribution reduces sound leakage while delivering deep, powerful bass. [Lightweight and Comfortable Wearing & IP56 Waterproof] The ergonomic design ensures a comfortable fit and lightweight design. The lightweight design weighs just 5.8g per earbud, reducing listening fatigue. The symmetrical design eliminates the need to distinguish between left and right earbuds; the earbuds automatically distinguish between left and right when worn. The IP56 waterproof rating ensures worry-free use even during exercise or sudden rain. The app is equipped with a drainage function that forcibly expels moisture that has seeped through the mesh. [28-Hour Playtime & Fast Charging] A single charge provides 7 hours of music playback with the earbuds alone, and 21 hours with the charging case, providing reliable support for extended use. With fast charging, you can enjoy approximately 3 hours of playback in just 15 minutes, even if you suddenly need to go out or commute to school or work. Enjoy your favorite sound anytime, anywhere. [Open-ear design and safety] The open-ear design leaves your ears unblocked, allowing you to enjoy music and calls while naturally hearing the sounds around you. It also detects potentially dangerous sounds in your surroundings, ensuring safety.
