Ears are not perfect. As with every part of your body, your hearing gets worse over time. Yet today’s music isn’t optimized for you and your hearing. It’s unlikely that you’ll be able to enjoy music to its full potential. We’ve spent the last years testing half a million ears. Our medically certified (CE) hearing test and music apps help us understand the way you hear — like no other company before. This data helps us to form your earprint. It’s your own key to personalized sound.
