Noble Audio foKus Amadeus
The latest FoKus iteration draws inspiration from Mozart's early compositions, masterfully merging classical influence with modern acoustic technology. The distinctive red chassis, an homage to Mozart's iconic tailcoat houses precision-engineered custom drivers that exemplify Noble's dedication to audio devices that excel in both aesthetics and performance.
Named after Mozart's inaugural recognized work, the Amadeus K1, these earphones deliver an expressive, immersive listening experience characterized by exceptional clarity and tonal refinement. The FoKus Amadeus represents Noble's philosophy that premium audio should engage not merely the ears, but evoke emotional resonance through meticulous sound reproduction and thoughtful design elements.

Building upon the acclaimed FoKus Rex5 platform, the Amadeus incorporates Audiodo Personal Sound technology which is a sophisticated hearing calibration system that precisely measures auditory response characteristics in each ear to generate individualized acoustic compensation profiles.
This proprietary algorithm constructs a customized frequency response curve that remains persistently stored within the earphones' onboard memory, functioning autonomously across all connected devices without requiring continuous software mediation.
The calibration process effectively addresses bilateral hearing asymmetries, enhancing spatial imaging accuracy and frequency response linearity. Audiodo's implementation reveals previously obscured micro-details while optimizing overall tonal balance, ensuring the acoustic presentation adapts to the user's specific auditory physiology rather than forcing adaptation to a standardized tuning paradigm.
