Japan's completely wireless earphones: aiming for the apex in sound

It is equipped with a hybrid triple driver, the likes of which is nearly non-existant for TWS around the world. We conducted tuning and acoustic design for beautiful, complete playback of everything from very low pitch ranges to high pitch ranges. It has a base of flat tone balance, and at the same time offers highly superior clarity; it makes vocals sound radiant, as though the singer was before your eyes.

Hybrid Driver

A hybrid between a dynamic driver, which has low warping in low pitch ranges, and a balanced armature driver, which is highly sensitive, high speed, and is good at replay in the mid- and high-pitch ranges is an ideal structure for a speaker. However, designing cross over circuits and miniature versions, and it consumes a lot of electricity, and the reality is that it is not often seen in wireless earphones. AVIOT used all of their portable integrated technology and power saving technology to make portability and playback over long periods possible.

An airy lightness, unlike any hybrid TWS

With the latest QCC3020 and the low energy design, it has a light body, at only 5.4 grams per side, and can continuously play for a maximum of 7 hours.

*Play time may be shorter when using a more high quality apt X codex, and may depend on broadcast status and volume.

The charging case, to protect its high function and recharge

Light (about 51g) and with a sleek design, it holds roughly 500mAh, and allows for roughly 3 recharges. We used a USB Type-C terminal to increase convenience.

More connections with AVIOT

With our high frequency circuit technology design and implementation knowhow, we have designed a new internal antenna inside of the earphones. We succeeded in suppressing sound drop out, even in places with high interference, such as inside of trains or stations.

Aluminum composite body

The knurled portion of the earphones are made using our best parts made from pure duralumin. It is not only pleasing to the touch, but also helps prevent the effects of outside noise.

AVIOT exclusive earpieces by SpinFit

It includes the CP355 earpieces from SpinFit. This not only improves wear-feel, but also improves the feeling of the low pitch ranges and the reality of the mid- and high-pitch ranges.

2 color options：Black and Silver
