Equipped with a customized dynamic driver featuring an LCP+PU composite diaphragm, the Airoso achieves ultra-low distortion and consistent performance across various listening volumes. This driver is designed to provide a well-rounded sound with a balance of deep bass and crystal-clear highs. Building on the success of the Allegro, the Allegro Mini was designed with the same dedication to high-fidelity sound but in a more compact and portable form. Both the Allegro and Allegro Mini excel in portability, but the Allegro Mini takes it a step further with its sleek, all-aluminum alloy body.
