Five-Factor Fusion

Project Ace harmonizes the quintessence of sound quality, balance, expansive soundstage, dynamic range, and musicality into one unparalleled listening experience.

Powerful 12mm Dynamic Driver

Boasting 1.44 times more air-pushing area than conventional 10mm drivers, and a staggering 2.25 times more than 8mm ones, Project Ace sets a new standard in driver efficiency for deep, rich bass and detailed midrange.

Beryllium-Plated Diaphragms

Crafted with precision, the beryllium-plated diaphragms offer lightning-fast response, delivering rich high-frequency detail and exquisite tonal texture with unparalleled accuracy.

Revolutionary Magnesium Alloy Dome

The dome's magnesium alloy construction, enhanced with lithium elements, enhances efficiency, resulting in exceptional bass performance while maintaining lightweight durability.

High-Efficiency Magnetic Core

By integrating magnesium alloy and beryllium diaphragms with enhanced copper coils, Project Ace achieves remarkable electro-acoustic conversion efficiency.

Ergonomic Design

Engineered for comfort and stability, Project Ace's ergonomic design ensures a snug fit for long listening sessions, while acoustically matched tubes optimize sound delivery.

Premium Materials

Crafted from lightweight yet durable T6063 aluminum alloy, Project Ace provides a solid acoustic transmission path, while high-precision CNC processes ensure a refined finish.

Advanced Cable Technology

Paired with Litz Type 5 coaxial shielded balanced wire and a specially formulated 8-core low internal resistance copper-silver blended cable, Project Ace delivers pristine signal transmission and enhanced separation.

Versatile Connectivity

With the innovative 4PIN-Lock multi-functional adapter system and 2-Pin(0.78) detachable cable design, Project Ace seamlessly integrates with a variety of devices for an immersive audio experience tailored to your preferences.
