Meze Audio 109 PRO Open-Back Headphones

The Meze Audio 109 PRO is a demonstration of Meze's 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.

DIAPHRAGM DESIGN

In a world of fast-paced technology, Meze bet on proven fundamentals. Their 50mm 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 they set for the 109 PRO, Meze focused their R&D efforts on materials research for each of the driver’s components.

W-SHAPED DOME

Made of a carbon fiber-reinforced 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), Meze 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. 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, Meze wanted the 109 PRO to be vivid and exciting, empowering the listener to connect with music on a deeper level. Carefully tuned by Meze's 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.

The spider-shaped structure and the acoustically transparent grille inside the earcup expose the driver from both sides, creating Meze's most open pattern to date. Following the principles of anthropometrics, the 109 PRO positions 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.
