Certified with the Technical Conformity Mark (2.4GHz band). ●Earphones are designed to fit comfortably in your ears and reduce fatigue, with a fingertip design and textured material for easy grip and less chance of dropping. ●A newly developed charging case that is lightweight and easy to carry. The angle of the case makes it easy to remove the earphones from the case, and the same textured material as the earphones makes it less likely to drop. Four types of earpieces (XS, S, M, L sizes) are included, made of soft silicone for optimal sound quality and fit. Highly waterproof IPX5/7 rating means the earphones can be washed with water. Even if they get wet in the rain or sweat, there's no need to worry if you accidentally drop them in water. One-button operation allows for intuitive operation without any confusion. Volume adjustment during listening and calls can be done without stress. Enjoy clear, hands-free calls with either one or both earphones. Wind noise is reduced for peace of mind while talking indoors or outdoors. The sidetone function returns your voice to the earphones, making it easier to talk. This eliminates the need to speak louder than necessary, a common problem during phone calls. Other convenient features: * Simply remove from the case to turn on the power and use immediately * Fast Pair compatible, convenient when connecting to an Android device * Can be used with just one ear * Simultaneous left and right transmission method for a stable connection, resistant to sound interruptions * Low Latency Mode reduces the lag between sound and video * Approximately 7 hours of continuous playback, up to approximately 21 hours of playback * Multi-pairing function allows you to register multiple devices
