• Balanced, yet musical sound signature
• Robust build, crafted from a solid block of pure aluminum
• OCC 4core silver-plated copper cable

Purity and Strength

The RE3PRO's housing is crafted from pure aluminum material, precisely sculpted using advanced 5-axis CNC machining from a single solid block. This meticulous process eliminates unwanted resonances and shields against external electromagnetic interference. The rigid yet lightweight structure ensures the driver's linear movement remains accurate, delivering pure, distortion-free sound reproduction.

The housing undergoes a fine sandblasting treatment to create a smooth, premium matte texture, then is anodized to boost scratch and corrosion resistance. The top plate's edge is finished with a precision diamond C-cutting, adding a refined sparkle that shifts subtly with the light.

The combination of 5-axis CNC precision and sophisticated surface finishing embodies Ucotech's commitment to premium build quality and enduring durability, keeping the RE3PRO pristine and elegant, year after year. 

10mm Dynamic Driver

At its core, a next-generation 10mm dynamic driver with dual magnets and a dual-chamber design maximizes magnetic force for precise diaphragm control and punchy bass. 

CNT Diaphragm 
The Carbon Nano Tube-coated diaphragm is exceptionally lightweight yet highly rigid, with superior internal damping properties that suppress unwanted resonance and breakup modes. 

CNT maintains structural integrity under vibration, minimizing flexing and partial vibrations. This allows for a more ideal piston-like motion across its frequency range, resulting in tighter bass, clearer mids, and crisp yet smooth highs with reduced distortion. 

SUS304 Driver Cavity
High-density SUS304 stainless steel stabilizes internal air pressure and reduces vibration, preserving tonal accuracy across frequencies.

Dual Magnet and Dual Cavity
This configuration increases magnetic flux density, providing stronger driving force for the diaphragm. This results in quicker transient response, deeper bass impact, an improved overall efficiency for a more dynamic sound.

Tuned for Balance

Through a unique internal pipe duct, the RE3PRO achieves a flat yet musical signature. A custom pipe within the housing regulates airflow and controls standing waves, tightening bass without bloat. The pipe's inner diameter is tuned to shape bass roll-off and extend mid-to-high frequencies naturally. This maintains clarity, prevents vocal masking, and delivers detailed treble free of harshness. 

OCC Silver-Plated Cable

The detachable 0.78mm 2pin cable uses high-purity OCC copper with silver plating for low resistance and superb signal transmission. A balanced 4.4mm plug ensures better channel separation and a lower noise floor.
