Meze Audio 109 PRO Headphone
The first dynamic open-back headphone from Meze Audio, 109 PRO is a demonstration of our commitment to go beyond the faithful reproduction of sound to deliver pure emotion.
"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 favourite music makes us feel.”
Antonio Meze
Lead designer and Founder of Meze Audio
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.
Our search led to developing the 109 series Dual-Composite Diaphragm – a combination of Beryllium-coated polymer, cellulose - carbon fiber composite and copper-zinc alloy.
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.
Our search led to developing the 109 series Dual-Composite Diaphragm – a combination of Beryllium-coated polymer, cellulose - carbon fiber composite and copper-zinc alloy.
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.
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 in-house engineering team, it 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 for the most natural listening experience possible.
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 robust self-adjusting headband spreads the weight out to deliver even pressure for any head shape and size.
SUPERIOR BUILD EQUALS 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.
CRAFTED FOR 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 typical headphones.

Great stuff
Seemed to work as well as or better than some more expensive catalytic converter cleaners. I put it in while at 1/3 tank and my Check Engine light went out almost immediately once I started driving. My Tundra has almost 230,000 miles and still runs great but was getting a little harder to start after I switched from full synthetic oil to conventional. I’ll never do that again and immediately switched back but the damage was done. Check engine light came on and I had to crank longer to get it started. Adding this Liquid Moly fixed both issues temporarily. I have to wonder if this was used regularly, say every 3 months, if it would clean the catalytic converter more permanently?

Nice Filter Wrench for my Volvo V70XC!
Size: 86mm x 16
I was needing a filter wrench for my 2001 Volvo V70XC and couldn't find anything that fit from the local auto parts stores. Not knowing what to expect, I took a chance on this one since most of the reviews were 5 star and the price was exceptional.
When I received it, I was quite pleased with the construction and finish. I have a brand new oil filter housing for my Volvo (since the one currently on my car is chewed up from the former owner using slip-jaw pliers or something on it) and the fit is perfect! I have worked as a mechanic my whole life (aircraft & automotive), and spent a couple of years as a technician at an automotive dealership and I can say that the tool looks like it is designed for heavy-duty use.
The stamped steel housing is thicker than those found in local auto parts stores and the drive adapter has a thick arc welded bead along the inside of the tool. So, it appears to be made to hold up to some fairly heavy torque. Although the product description states that it is 1/2", the drive adapter is actually made for direct attachment to a 3/8" drive. Perhaps this error stems from the fact that they offer a much larger wrench (118-131mm) and this is a more accurate description of their other offerings.
The 3/8" drive adapter works perfectly and a 21mm socket fits nicely on the external hex. Fits with SAE sizes are a mixed bag, though. I was able to attach a 13/16" 12-pt. box-end wrench, but not the opposing open-end. A similarly sized 13/16" 6-pt. socket was extremely tight, so I wouldn't recommend this size and would just go with the 21mm if you had to use the external hex. Otherwise, just use the 3/8" drive adapter for easiest use of this tool. The adapter also incorporates ball detents on all four sides of the internal 3/8" drive, so your ratchet or extension won't easily fall off while in use.
Since this tool is made for oil filter removal & installation, I'm sure that it will deliver as promised. I'll post an update after my next oil change and I get a chance to use it and install the new filter housing I have.
