An orchestra in your ears
Aiming for miniaturization and even higher sound quality, we have brought to fruition various technologies at a high level, such as thoroughly improving not only speaker drivers and PCBs, but also each and every internal wiring.

Equipped with a newly designed hybrid triple driver that is extremely musical and informative
The fully remodeled TE-BD21j also uses a hybrid driver equipped with three drivers. The dynamic driver uses an ultra-lightweight, high-rigidity PET titanium composite diaphragm with a slightly smaller diameter to improve responsiveness. And for the balanced amateur driver, at the same time as precisely analyzing the matching with this high-performance dynamic driver with a computer, AVIOT's skilled engineers perform a long listening test and carefully select it, and tune it to the order of 0.1 dB. .. We succeeded in reducing the feeling of distortion in the crossover band to the utmost while increasing the amount of information in the mid-high range.

Hands-free and comfortable calling.
AVIOT uses a high-sensitivity MEMS microphone to improve call quality. With the synergistic effect of the cVc noise canceling function, you can talk with clear voice with less environmental noise and echo.

High sound quality with comfort and stamina
Newly adopted a high-performance touch sensor with high sensitivity and few errors. You can comfortably operate basic functions such as play, pause, song forward, song return, volume control and incoming call without putting pressure on your ears. In addition, the synergistic effect of AVIOT's proud low power consumption technology and the latest SoC has realized continuous playback for up to 9 hours * despite the lightweight body of only 5.2g on each side.

Catch the surrounding sounds firmly.
Equipped with an ambient microphone that captures ambient sounds while wearing earphones with the built-in microphone.

Drip-proof performance that is safe against sweat and sudden rain
IPX4 level waterproof performance has been achieved * by waterproofing. 
*Earphone body only (Charging case is non-waterproof)
