The world's first * hybrid triple driver for a completely wireless earphone. The audio expert team of AVIOT has gathered all the power to make a sound design that sounds beautifully from the ultra low range to the high range, and carefully tunes the 0.1bB level. It does not take the illusion of boosting the low range and high-quality sound, and based on a flat tone balance to the last, both the sound image localization feeling that the vocals give up and floats in front of the eyes, and the spacious sound field feeling I was allowed to. Please try the sound quality of the highest level of complete wireless earphones, created with exactly the same idea as high-end full-size audio. * As of July 2019. Our investigation.
