The KEFINE Quatio combines 2 Dynamic Drivers, 2 Balanced Armatures, and interchangeable tuning nozzles to deliver premium HiFi sound. Featuring a modular 3.5mm/4.4mm cable, CNC aluminum housing, and customizable sound signatures, it is ideal for audiophiles seeking exceptional performance and versatility.
Description
The KEFINE Quatio utilizes a sophisticated quad-driver hybrid configuration, combining a 10mm Diamond-Like Carbon (DLC) Dynamic Driver for highly detailed midrange and treble reproduction with an 8mm PU+LCP Dynamic Driver dedicated to delivering deep, textured, and controlled bass. Complementing these dynamic drivers are two custom-balanced armature drivers, which reproduce upper-midrange and high frequencies with exceptional precision and clarity.
Its advanced three-way hybrid crossover system, integrating both acoustic tubing and electronic crossover circuitry, ensures smooth driver integration while minimizing distortion and frequency overlap. This results in a highly coherent sound signature with excellent instrument separation and imaging.
One of the Quatio’s standout features is its three interchangeable stainless-steel tuning nozzles, allowing users to tailor the sound signature:
- Gold Nozzle: Reference-neutral, transparent, and analytical sound.
- Silver Nozzle: Balanced tuning suitable for all music genres.
- Black Nozzle: Warmer signature with fuller bass and smoother treble.
The shells are precision-machined from high-grade CNC aluminum alloy, offering excellent durability, resonance control, and a premium finish while maintaining an ultra-lightweight 7.5g design for extended comfort.
The included 4-strand silver-plated OFC cable features a modular plug system, allowing quick switching between 3.5mm single-ended and 4.4mm balanced outputs without replacing the cable. The 0.78mm 2-pin detachable connector also supports future cable upgrades and Bluetooth adapters.
