MLD Driver - Large Tilt Angle Acoustic Structure - Concentric Circle Wearing System
The AR5000 headphones feature an innovative MLD (Multi-Layer Distributed) driver, a carefully designed high-tilt acoustic structure and a patented concentric circle wearing system that provides a relaxed and rich sound, a deep and wide soundstage, a comfortable wearing experience and an authentic reproduction of the exquisite texture of music.
 
Pure Stable Sound
This dynamic driver is unlike any other
The AR5000 headphones feature a 50 mm dynamic driver with an open back and an innovative structure. The MLD (Multi-Layer Distributed) diaphragm provides a balance of stiffness and damping, further solving the problem of break-up often found in large drivers. This reduction in distortion across the entire frequency range results in high transparency and a frequency response that easily extends to 40 kHz, allowing the AR5000 to faithfully reproduce even intricate musical details.
 
Powerful and Deep Bass
Big and Majestic Presence
The newly developed acoustic suspension and airflow system improve the linearity of the cone movement and equalise the internal pressure and sound velocity in the transducer, resulting in deep and powerful bass and a smooth and dynamic performance. Whether it's an exhilarating symphony or a thunderous roar, the AR5000 can effortlessly reproduce the size and intensity.
 
Comfort Acoustic Design
The innovative "concentric circle" fitting system, combined with the lightweight design, makes for a superb wearing experience. The size of the headband and the overall curvature are adjusted to the millimetre to ensure a perfect fit for every head shape and avoid any feeling of pressure or foreign bodies. The ear cup is made of breathable, acoustically slow-rebounding sponge and designed to completely cover the ears, allowing for extended listening sessions without discomfort.
