109 PRO is a demonstration of our commitment to go beyond the faithful reproduction of sound and 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 favorite artist, song or instrument, when all distractions are removed.

"At the core of it all, music is an expression of emotion, a celebration of life and a token of everlasting memories. Every part of the 109 PRO, from the premium materials we used to the intricate engineering, embodies that same emotion our favorite music makes us feel.”

Antonio Meze, Lead Designer and Founder of Meze Audio.

SUPERIOR BUILD EQUALS SUPERIOR EXPERIENCE

The 109 PRO follows our highest standards for comfort and ergonomics. Once placed on your head, the headphones become unnoticeable, leaving you with nothing but the music.

Walnut wood, cast zinc, manganese steel and vegan leather complete each other to create a comfortable, lightweight, yet highly durable structure.

DIAPHRAGM DESIGN

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

In order to meet the acoustic goals we set for the 109 PRO, we focused our R&D efforts on materials research for each of the driver’s components.

W-SHAPED DOME

Made of a carbon fiber enforced cellulose composite, the 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 reduce resonances that may lead to harmonic distortion.

ULTRA-THIN TORUS

The torus surrounding the dome is composed of Beryllium-coated semicrystalline polymer, measuring 22 microns in thickness. By applying the Beryllium coating through Physical Vapor Deposition (PVD), we increased the stiffness and durability of the driver, while still keeping it light enough to achieve a fast transient response. These qualities are also enhanced through the corrugations on the torus, which are precisely carved at a 45.5° angle.

Beryllium’s high damping qualities also help suppress unwanted resonances, giving the 109 PRO its neutral, vivid and transparent character.

ALUMINIUM FRAME

The diaphragm is encased in a high-precision aluminum frame, together with the neodymium magnet. Manufactured using CNC machining, the frame offers superior rigidity, strength, and thermal stability to retain surface flatness.

COPPER-ZINC STABILIZER

The copper-zinc alloy stabilizer, positioned around the membrane, improves the absorption of vibrations to further reduce distortion.
