Technology
Our technologies.
Every detail, from the fit to the crossover, designed in our lab.
Hybrid Fit™
A custom shell from your impressions, with a soft silicone tip at the end. The stability of custom with the comfort of universal.
Learn moreImmersive Mode™
A switch for the bass. Off, the lows blend gently into the mix. On, they turn fuller and more physical, without any mud. Your choice.
Flex Fit Pro™
A flexible 3D resin in the part that goes into the ear canal. Within minutes it takes on your ear's temperature and turns softer and more comfortable than a conventional acrylic mould.
Perfect Fit™
We scan your impressions, design every shell digitally and 3D-print it, for the most comfortable fit.
Complex™
A crossover design that gets the most out of every driver: balanced sound, coherent phase, low distortion and matched left and right.
