About this product: 【Bluetooth 5.3 & Automatic Pairing】These wireless earphones are equipped with the latest Bluetooth 5.3 + EDR technology and AAC, which has renewed the data transfer speed and connection stability. It minimizes the issues of previous Bluetooth earphones such as no communication, sound skipping, sound distortion, delay, and fast power consumption, and significantly improves energy saving and connection stability. Once connected successfully, the next time you take the earphones out of the charging case, they will automatically pair with your smartphone. 【Hi-Fi High-Quality Sound & Hands-Free Calling】 These Bluetooth earphones support SBC and AAC audio decoding technology and are equipped with a 13mm dynamic driver, achieving clear and powerful sound. From deep bass to smooth mid-high frequencies, the balance is well-maintained, maximizing the immersion in music and allowing you to enjoy stereo music. Directional high-sensitivity microphones are built into both the left and right earphones, and they also feature ENC noise cancellation, which reduces ambient noise and allows the other party to hear your voice clearly, enabling hands-free calling. 【Fit & Touch Operation】 These Bluetooth earphones adopt an ergonomic design that fits well in the ear and does not cause pain or discomfort even after wearing them for a long time. Also, the earphones are unlikely to fall out of your ears even during exercise or jogging, so you don't have to worry about losing them. 【Long Playback & Type-C Fast Charging】 These completely independent Bluetooth wireless earphones are equipped with independently developed innovative power-saving technology and a high-performance battery, allowing the earphones to play continuously for about 5 hours on a single full charge. With the charging case, you can play for up to 25 hours, so you can use them all day without worry. Furthermore, the Type-C charging port is adopted, so the charging speed is significantly faster than Micro USB, and the charging time is greatly reduced.
