  • 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.

    Hybrid driver
    A hybrid type that combines a dynamic driver with low distortion in the low frequency range and a balanced armature driver that is highly sensitive, high-speed, and good at playing mid to high frequencies, is one of the ideal speaker configurations. However, it is difficult to design and miniaturize crossover circuits, and power consumption increases, so there are few examples of adoption in wireless earphones. AVIOT has mobilized its integration technology and power-saving technology to clear the challenge. Realized downsizing and long playback.

    The dynamic driver is equipped with a large neodymium magnet to enhance the responsiveness to the utmost limit, and uses an ultra-lightweight, high-rigidity PET titanium composite vibration plate that has been carefully selected through repeated listening tests. The balanced armature driver uses a custom product that is tuned exclusively for AVIOT, focusing on the good connection with this high-performance dynamic driver.
