TENORA features a front housing design, much like the previous 9iNE, that places the dynamic driver as close to the ear as possible. Compared to the MIROAK-II or LOAK2, the distance from where the driver is mounted to the sound outlet in TENORA is notably shorter. This structure minimizes sound attenuation over that distance, delivering the sound from the driver to the ear with minimal loss.
Such a design isn’t feasible with MIROAK-II or LOAK2, which both use 10mm dynamic drivers, making it one of TENORA’s key advantages in employing a smaller dynamic driver.
