Hybrid Adaptive ANC

Reduce noise up to 99%
Block out ambient sounds with Hybrid Noise Cancellation. Adapts automatically between strong, moderate, and light modes so you hear only what matters. Transparency Mode lets some outside sound in when needed.

Immersive Sound
Static Spatial Audio surrounds you using Cinema and Concert modes. Each mode optimises width, depth, and clarity for an immersive experience in movies and music.

Precision Sound

Packed with Power
CMF Headphone Pro features 40 mm drivers with nickel-plated diaphragms that reduce distortion and sharpen clarity. A 16.5 mm copper voice coil moves more air for deeper, fuller sound. Precision-tuned bass duct and dual-chamber design create rich, textured sound.

LDAC + Hi-Res Certified Audio
Supports LDAC and wired/wireless Hi-Res certifications for high-resolution audio in every mode.

Personal Sound
Uses Audiodo technology to create a Personal Sound profile tailored to your hearing. A quick three-minute test calibrates your audio and stores it directly on the headphones for a consistent, personalised experience.
