The OPUS 1 provides the same processing power as the OPUS 2, but with a different design. Users choose the OPUS 1 if they prefer to perform adjustments on the processor.
The OPUS 1 has all the same features as the OPUS 2 including FineHearing
and Automatic Sound Management
FineHearing allows users to appreciate the fine structure of sound. Fine structure is necessary for the best possible sound quality and music listening experience.
Automatic Sound Management allows for seamless transitions between quiet and noisy listening environments, whether you are listening to music or everyday sounds, all without pushing buttons or removing the processor from the ear.
