KEFINE Quatio 2DD+2BA Hybrid IEMs

KEFINE introduces the Quatio, its first-ever hybrid in-ear monitor designed for audiophiles seeking both versatility and musicality. Equipped with 2 dynamic drivers (10mm DLC + 8mm PU+LCP) and 2 balanced armature drivers, the Quatio delivers a warm, lush, and highly engaging sound signature.

To ensure precision, it adopts a three-way crossover system combining acoustic tubes and electronic circuitry, directing each driver’s output smoothly across the frequency range. The result is a refined presentation with deep, textured bass, detailed mids, and airy highs.

The Quatio also features three tuning options via replaceable nozzles:

• Gold Nozzle – Transparent, accurate, neutral sound
  
• Silver Nozzle – Balanced and natural
  
• Black Nozzle – Warm, smooth, and relaxed
  

Crafted from CNC-machined aluminum alloy, the housings are lightweight yet durable, finished with fine polishing and anodizing for a premium feel. At just 0.06mm shell thickness, the ergonomic design ensures comfort for long listening sessions.

Included is a high-purity silver-plated copper cable (4 strands, 392 cores) with a modular plug system, supporting both 3.5mm and 4.4mm terminations. A selection of eartips is also provided, allowing users to achieve the perfect fit and sound.
