Product Research

Features

Overview: The 109 PRO over-ear headphones is the first dynamic, open-back headphone from Meze Audio. It features a new 50mm dynamic driver and beautiful black walnut wood ear cups. The 109 PRO comes with two interchangeable audio cables, a 1/4-inch adapter, cable pouch, and a zippered carrying case. The headphones are covered by a 2-year manufacturer's warranty.

50mm Driver: The new 50mm drivers were designed from the ground up with a focus on finding the materials that would produce the most accuracy, speed, and dynamic range. The W-shaped dome driver is made of a carbon fiber-enforced cellulose diaphragm for superior detail and clarity. This lightweight composite material is more durable than materials traditionally used in dynamic drivers, and helps to reduce unwanted resonances that cause distortion. The super-thin, torus-shaped surround is made of Beryllium-coated semicrystalline polymer that is only 22 microns thick. The Beryllium coating is applied using Physical Vapor Deposition (PVD), which increases the stiffness and durability of the driver, while maintaining its light weight. Beryllium also has high damping qualities to better control the driver. The surround also features corrugations cut at a precise 45.5° angle for enhanced strength. To absorb vibrations, a copper-zinc alloy stabilizer ring is positioned around the membrane, reducing distortion. The diaphragm is encased in a high-precision, CNC-machined aluminum frame with a neodymium magnet for high strength and thermal stability.

Ear Cups: The 109 PRO's beauty is found in the black walnut wood used for the headphone's acoustic chambers. The wood is harvested from mature trees that have reached the end of their life cycle. This protects the environment by leaving room for new growth. The open-back ear cups feature an acoustically transparent grill that exposes the driver from both sides. Inside, the driver is positioned at a precise angle and distance from the ear for a natural listening experience. The ear cups are attached to the frame through a spider-shaped structure that allows the cup to follow the shape of the listener's head. The luxuriously soft velour cushions surround the ears for comfort during long listening sessions. More breathable than leather, the velour prevents overheating and sweating that detract from your listening enjoyment.

Headphone Frame: The 109 PRO headphones have a sturdy, but lightweight spring steel frame with a self-adjusting vegan leather headband to evenly distribute the weight and pressure for any head shape or size. The headphones should become unnoticeable when you put them on, leaving you with nothing but the music.

Cables: Included with the headphones are two cables of different lengths, one designed for portable use (55"), and the other for home use (123"). Both cables have flexible TPE (thermoplastic elastomer) jackets, with separate left and right earcup plugs (3.5mm) and a straight 3.5mm input plug. The plugs feature black aluminum casings and gold-plated connectors. A snap-on gold-plated 6.3mm adapter is included for connecting the headphones to your home audio components, headphone amps, or DACs equipped with 1/4" jacks. The cables and adapter can be stored in the supplied polyurethane leather cable pouch.

Case: The 109 PRO headphones can be stored in the supplied EVA (Ethylene Vinyl Acetate) molded carrying case. The case features the Meze Audio "lyre" logo, and has a zippered closure.

Customer Q&A

1 question already asked

Q
Would using a 4.4mm to 3.5mm adapter potentially harm these headphones?
mike  Jun 04, 2025
1 answer
A
It is possible, Mike. 4.4mm is a balanced output, with 3.5mm being unbalanced. Using an adapter or connecter that does not properly convert the balanced 4.4mm signal to unbalanced 3.5mm could cause poor sound or potential damage to your headphones.
