Meze Audio 109 Pro Open Back Headphones
Meze Audio 109 Pro Open Back Headphones
A PERSONAL JOURNEY THROUGH SOUND
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.
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.
EXPLORING NEW HORIZONS
STARTING WITH THE BASICS
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
Symmetrically placed on each side of the diaphragm, the neodymium magnets are specifically arranged into a Hybrid Array to create the efficient Isodynamic magnetic field required for a uniform activation across the whole diaphragm surface.
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.
ACOUSTIC DESIGN
Through its open-back design, we wanted the 109 PRO to be vivid and exciting, empowering the listener to connect with music on a deeper level.
Carefully tuned by our engineering team, 109 PRO offers emotionally engaging sound with great detail, clarity and just the right amount of punch. Its organic character, paired with superior dynamics, excellent imaging, and full-bodied vocals bring soul-stirring details to life. Besides, it’s easy to drive from most devices, whether we’re talking portable sources or intricate home setups.
The spider-shaped structure and the acoustically transparent grill inside the earcup expose the driver from both sides, creating our most open pattern to date.
Following the principles of anthropometrics, we positioned the driver at a precise angle and distance from the ear, to achieve an ideal anatomical fit.
Velour cushions comfortably surround the ears, providing the optimal seal to create natural sound. As velour is far softer and more breathable than leather, it also prevents sweat and overheating during lengthy listening sessions.
The self-adjusting headband spreads the weight out to deliver even pressure for any head shape and size.
SUSTAINABILITY THROUGH LONGEVITY
As our choices of today can have a great impact on 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.
