By evolving chip technology and algorithms, and through dynamic monitoring and calculation, multiple sound sources are synthesized and sound is rearranged. Compared to the previous generation Bluetooth 5.0 chip, power saving and connection stability have been significantly improved. It effectively solves conventional communication problems such as sound skipping, interruptions, and delays. The lag between video and audio during video viewing has also been greatly reduced from the previous model, enabling a smooth gaming and video viewing experience. 【Open-Ear Design for Comfort】 Equipped with innovative earphone Bluetooth pairing technology, after pairing with your smartphone for the first time, you can instantly connect again simply by opening the charging case lid. When wearing the earphones and listening to music, you can enjoy the open feeling of music without blocking your ears. The innovative ear-clip design doesn't need to be stuffed into the ear, reducing irritation to the eardrum, relieving pressure on the ear, and making it more comfortable even after long hours of use without pressure. 【Up to 30 Hours of Playback & LED Battery Level Display】 With a large-capacity battery and an energy-saving design, the earphones alone can enjoy up to 6 hours of continuous music playback on a full charge. Combined with the battery case, a total of up to 30 hours of use is possible. You can use it without worrying about running out of battery during your commute, on airplanes, or on long-distance travel such as the Shinkansen. The battery level is displayed on the LED screen, so you can easily check the battery level of the charging case even in a dark environment. 【High-Sensitivity Touch Operation & Smooth Operation】 The charging case for the earphones is small enough to fit in the palm of your hand and can easily be put into any pocket. It combines ergonomic design and a highly integrated acoustic structure, achieving a perfect fusion of comfort and performance. It minimizes the burden on the ears and provides a natural and comfortable fit that you'll forget you're wearing even after long hours. With a high-sensitivity touch operation design, you can adjust the volume, play/pause music, answer/end/reject calls, skip to the next/previous song, and activate Siri with touch operations without having to take out your smartphone.
