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.
Aiming for the pinnacle of Japan's complete wireless earphone
Dynamic and balanced armature driver movements in the crossover band with a hybrid triple driver, advanced acoustic design with approximately 2 years of trial and error, and a listening test of over 3,000 hours Even the slightest sense of incongruity due to the difference in characteristics has been suppressed to the limit, and it has succeeded in achieving both delicate and high-speed mid-high sounds and flat and low-distortion bass reproduction. (In order to bring out the original performance of a hybrid driver, we recommend aging for at least 30-50 hours. You should be able to enjoy the sound growth.)
Hybrid Drivers
By combining dynamic driver, which has wide reproduction frequency band and low distortion in low-range, with balanced armature drivers, which has high sensitivity, high speed and good reproduction in mid- and high ranges, the hybrid type is deemed to be an ideal speaker structure for earphones. Yet, due to the difficulties of crossover circuit design, compact size and large power consumption, it is rarely used in wireless earphones. AVIOT mobilized all of their integrated technology and power saving technology to make miniaturization and long playback time possible.
Light as feather, unlike any hybrid TWS
With the latest SoC QCC3020 and the low energy design, it has a light body, at only 5.9g per side, and can continuously play for a maximum of 7 hours.
*Playtime may be shorter when using a higher quality aptX codex, and may depend on radio wave condition and volume.
Charging case for high performance and recharge
With lightweight (about 51g) and sleek design, it holds roughly a capacity of 500mAh, and allows for roughly 3 recharges. USB Type-C terminal is adopted to increase convenience.
More connections with AVIOT
High frequency circuit design technology and implementation know-how are utilized to design a new internal antenna. Even in places with high interference, such as trains or stations, audio dropout is successfully minimized.
Aluminum alloy body
The knurled portion of the earphones is crafted using our best parts made from pure duralumin. It is not only pleasing to the touch, but also helps prevent the effects of external noise.
Comes with a strap to prevent loss
Comes with a strap that connects both earphones so that they won't be lost if one side of the earphones falls. Even during sports such as running, you can use it without worrying about falling.
