WHAT IS ACAA TECHNOLOGY?

Go Inside ACAA to Discover How It Works

The Origin

In order to bring studio-quality sound to true wireless earbuds, we developed the unique Astria Coaxial Acoustic Architecture (ACAA) technology after discovering no existing headphone drivers could deliver the sound quality we desired.

Present Day

ACAA is a groundbreaking coaxial driver technology that integrates a dynamic driver and a customized Knowles balanced armature driver into a single body. </br></br>Sound is delivered directly to your ears with no interference between the treble and bass. The soundscape is expansive, and every detail within the music is delivered with precision accuracy.

The Future

With each new generation of Liberty Pro true wireless earbuds, ACAA technology will continue to evolve to bring you unique studio-quality listening experiences.
