Meze Audio 109 Pro Open Back Headphones

Meze 109 Pro Open-Back Headphones

The first dynamic open-back headphone from Meze Audio, the 109 Pro is a demonstration of our commitment to go beyond the faithful reproduction of sound to deliver pure emotion.

It all started with a purpose – creating joy. It’s about letting yourself get lost in sound, about that intimate connection you have with your favourite artist, song or instrument, when all distractions are removed.

Diaphragm Design

At the heart of the headphone is the 109 series Dual-Composites diaphragm featuring a Beryllium-coated semicrystalline polymer torus, a cellulose-carbon fibre composite dome and a copper-zinc alloy ring stabiliser.

The super-light but stiff cellulose composite reinforced with carbon fibre makes it possible for the W-shaped dome to reproduce high frequencies (5Hz-30KHz) with incredible detail, clarity and definition. This composite is superior to conventional alternatives used in dynamic drivers, and its low mass and stiffness helps avoid resonances that may lead to harmonic distortion.

The ultra-thin torus (22 microns) surrounding the dome is constructed out of a
Beryllium-coated semicrystalline polymer, which contributes to greater clarity and a faster transient response. The high dampening qualities of Beryllium also suppress
unwanted resonances, leaving listeners with a more neutral, vivid and transparent
experience.

Around the circumference of the membrane, the ring-shaped stabiliser made of copper-zinc alloy improves the absorption of vibrations to reduce distortion even further.

The diaphragm is encased in a high-precision machined aluminium frame that has
superior rigidity to typical plastics frames and retains perfect surface.
