Description
Materials suitable for crafts
The Mason Asahi shell is crafted from rare hardwoods and high-strength carbon fiber composite. These materials are pressed into shape using precision molds, resulting in a design that is both functional and artistic. The optical surface evokes the first light of dawn. Warm golden wood grain blends into woven carbon structures, blending organic and modern elements in a way that feels timeless and balanced.
It looks like sound. It feels like presence.
Next-generation 3D Bone Conduction System
Mason Asahi continues the legacy of the Mason series, offering a bold reinterpretation of space, texture, and sound. At its heart is a next-generation 3D Bone Conduction System , engineered to enhance spatial perception without physical vibration. Combined with twelve precisely tuned balanced armature drivers, Mason Asahi creates a listening environment that feels open, dimensional, and emotionally authentic.
UM 3D Bone Conduction System
Our UM 3D bone conduction array positions a three-axis bone conduction system along the X, Y, and Z planes, reconstructing sound like never before. The result is:
- Realistic spatial depth
- improved imaging and positioning
- Vibrations that you can feel throughout your entire skull – not just in your ears
With this three-axis layout, Mason Asahi simulates how sound spreads through a room, conveying a sense of presence that simply cannot be achieved with conventional bone conduction.
Full frequency range, full-bodied sound
Mason Asahi uses three bone conduction drivers, each tuned to a specific part of the frequency range. Together, they deliver power in the low end, presence in the midrange, and enhanced detail in the high end.
- The bass is deeper and more structured.
- The mids are clearer and more expressive.
- The highs extend smoothly up to 35 kHz.
This multi-axis configuration allows bone conduction to contribute across the entire bandwidth, providing a more immersive and natural sound without altering the sound balance or causing fatigue.
Twelve balanced armature drivers. Six ways. Consistent tuning.
A total of twelve balanced armature drivers are distributed across three frequency bands for optimal performance:
- 4 woofers for a clear, rich bass
- 4 midrange drivers for presence and smooth articulation
- 4 tweeters for detailed yet controlled highs
The six-way crossover ensures that each driver operates in its ideal range, delivering speed, resolution, and sonic accuracy that remain balanced at all volume levels.
Leather case, carefully crafted
The case is covered with Italian cowhide and lined with Indian goat suede.
- Outer shell in UM-typical blue
- Inner lining made of warm, tea-brown suede, soft as morning mist
- Structured, protective and haptically refined
The case reflects the same values as the headphones it protects – durability, sophistication, and understated luxury.
Two systems. One seamless experience.
Mason Asahi combines air and bone conduction into a single, seamless
architecture. This dual-pronged approach combines the soundstage and spatiality of natural bone conduction with the precision and detail of balanced armature drivers for a comprehensive, realistic soundstage.
The result is a more natural listening experience. Immersive, precise, and deeply captivating:
- The spatial projection is expanded, offering an enveloping width and layering from front to back.
- Multiple conduction paths provide a subtle dynamic texture.
- The improved coupling design increases efficiency by more than 2.3 times compared to our previous bone conduction systems.
UM Fantasy Custom Cable
