109 Pro

When first opening the Meze Audio 109 Pro Open Back Headphones it is hard to believe that they are a $1,400 pair of headphones, initial impressions of the presentation fit and finish are of a headphone that costs significantly more and then there is the sound performance that again reflects of product at a higher price point! The first dynamic open-back headphone from Meze Audio, 109 PRO is a demonstration of Meze Audio’s commitment to go beyond the faithful reproduction of sound to deliver pure emotion.

DIAPHRAGM DESIGN

The diaphragm is the heart of the headphone, producing the waves our brains ultimately perceive as sound. In order to meet the acoustic goals we set for the 109 PRO, we focused our R&D efforts on materials research, looking for the perfect balance between mass and stiffness that would maximize the sonic abilities of the headphone.

In a world of fast-paced technology, we bet on proven fundamentals. Our new 50mm dynamic driver, assembled and tuned with ultimate precision, allowed us to push the boundaries of speed, accuracy, and dynamic range.

Made of cellulose composite enforced with carbon fiber, the W-shaped dome is able to reproduce high-frequencies with incredible detail, clarity and definition. More durable than conventional alternatives used in dynamic drivers, yet lightweight, this composite helps us avoid resonances that may lead to harmonic distortion.

The ultra-thin torus surrounding the dome is composed of Beryllium-coated semicrystalline polymer, measuring 22 microns in thickness. With the Beryllium coating applied through Physical Vapor Deposition (PVD), we aimed to increase the stiffness and durability of the driver, while still keeping it light enough to achieve a fast transient response.

Beryllium’s high damping qualities also help suppress unwanted resonances, giving the 109 PRO its neutral, vivid and transparent character. Around the membrane, the ring-shaped stabilizer made of copper-zinc alloy improves the absorption of vibrations to further reduce distortion. The diaphragm is encased in a high-precision machined aluminum frame that has superior rigidity to typical plastics frames and retains perfect surface flatness, which is essential for the precision assembly with the diaphragm.

SUPERIOR EXPERIENCE

The 109 PRO is all about comfort – from the structural design of the headphone to the choice of materials, all decisions were carefully made to ensure the final product rises to our highest standard, in terms of ergonomics. Once placed on your head, the headphones have to become unnoticeable, leaving you with nothing but the music.

With this perspective in mind, we combined walnut wood, zinc, manganese steel and vegan leather in a comfortable, lightweight, yet highly durable structure.

SUSTAINABLY

HARVESTED WOOD

The black walnut wood we use for our headphones comes strictly from sources with a certificate of origin, harvested from mature trees that have reached the end of their life cycle. This way, the environment is being protected, leaving room for new life, while the old trees are shining once again, in the shape of a Meze headphone.

THROUGH LONGEVITY

The 109 PRO is crafted with utmost care for sustainability. As our choices of today can have a great impact in the world of tomorrow, we design products that last. We believe that a longer product lifespan means a smaller footprint Following this philosophy, the 109 PRO can be taken apart and serviced endlessly if ever needed, which can extend the life of the product beyond limit.
