Kefine has introduced its first hybrid in-ear monitors (IEMs), the Quatio, a meticulously engineered set of earphones designed to deliver a refined, musical listening experience. Featuring a quad-driver configuration—two dynamic drivers (DD) and two balanced armature drivers (BA)—the Kefine Quatio employs an innovative combination of physical acoustic channels and electronic crossover boards to offer a sound profile that is both lush and precise.

At the heart of the design are two dynamic drivers: a 10mm DLC diaphragm unit optimized for full-range sound reproduction and an 8mm PU+LCP diaphragm driver tasked with emphasizing low frequencies. These are complemented by two custom Knowles-balanced armature drivers, which focus on high-frequency ranges, exceeding the 5kHz threshold. The drivers are precisely tuned using a three-way hybrid crossover, ensuring seamless integration across the audio spectrum. The crossover features three independent acoustic channels, each leading directly to the ear nozzle, enabling unparalleled sonic precision by avoiding unnecessary blending of frequencies.

The Quatio offers users the flexibility to tailor their listening experience with interchangeable nozzles. Each nozzle is designed with a unique density filter, effectively creating three distinct sound profiles. The silver nozzle delivers a balanced output, the gold nozzle boasts an accurate and transparent sound signature, and the black nozzle offers a warm, bass-rich response for immersive low-end performance. This modular tuning system elevates the Quatio’s versatility, catering to different preferences and genres of music without compromising fidelity.

Constructed with precision-engineered CNC-machined aluminium alloy ear housings, the Quatio impresses with its robust yet lightweight design. The production process ensures tolerances as fine as 0.01mm, while advanced polishing and anodizing techniques result in a refined, textured finish. The housing’s minimal thickness of 0.06mm contributes to its reduced size while maintaining durability, ensuring a comfortable fit for extended listening sessions.

Complementing the IEM itself is a high-purity silver-plated oxygen-free copper cable. Featuring a braided design with 392 individual wire cores, the cable ensures efficient signal transmission and audio clarity. The modular termination system adds practicality, with both 3.5mm single-ended and 4.4mm balanced plugs included in the package. Additionally, Kefine provides a variety of ear tips to ensure optimal seal and comfort.

Priced competitively at $129.99, the Kefine Quatio combines high-end features with thoughtful engineering, setting a new benchmark for hybrid IEMs in its category. Whether you're a fan of rich bass, natural mids, or sparkling treble, these earphones offer customization and performance to satisfy discerning ears.
