Introducing the Kefine Quatio - A Versatile Hybrid In-Ear Monitor for Audiophiles

Kefine introduces its first hybrid in-ear monitor for audiophiles—the Kefine Quatio. This IEM features a total of four drivers: two dynamic drivers and two balanced armature drivers, working together to produce a warm, lush, and musical sound. The Quatio in ear monitor uses a special three-way crossover system, combining both physical and electronic elements for precise sound separation. You can easily adjust the sound to your liking with three sets of interchangeable nozzles, each offering a different sound profile. The wired earphones are built with durable, CNC-machined aluminum alloy shells for a premium feel. Kefine also includes a variety of ear tips for the perfect fit and a high-quality silver-plated copper cable. The cable comes with both 3.5mm and 4.4mm modular plugs, making it easy to use with different devices.

KEFINE’S FIRST HYBRID QUAD-DRIVER IEM FOR SUPERIOR SOUND

The Kefine Quatio marks Kefine’s debut in hybrid driver IEMs. Previously, Kefine was known for its popular single-driver models like the Klean, Klanar, and Delci. Now, with the Quatio in ear monitor, they introduce a quad-driver setup that includes two dynamic drivers (one 10mm and one 8mm) and two balanced armature drivers in each earpiece. This combination is designed to deliver a high-fidelity listening experience, blending powerful bass with clear mids and highs.

ADVANCED THREE-WAY CROSSOVER FOR PRECISE SOUND SEPARATION

The Kefine Quatio uses a special three-way crossover system to manage its sound. This system combines both physical acoustic tubes and an electronic crossover board. There are three separate sound channels—one each for the 10mm dynamic driver, the 8mm dynamic driver, and the dual balanced armature drivers—which all lead directly to the ear nozzle.

ADVANCED DLC AND PU+LCP DIAPHRAGMS FOR PRECISION TUNING

The 10mm driver, with its DLC diaphragm, delivers clear and detailed sound across all frequencies. The 8mm driver, made with a PU+LCP diaphragm, is focused on boosting the bass. The dual balanced armature drivers handle the high frequencies above 5 kHz, making treble sounds crisp and lively. Thanks to this smart crossover design and the four specialized drivers, the Quatio provides a rich, well-balanced, and high-quality listening experience.

CUSTOMIZABLE SOUND TUNING WITH THREE INTERCHANGEABLE NOZZLES

The Kefine Quatio is a very flexible pair of IEMs because it offers three different sound tuning options. You can easily change the sound by swapping out the nozzles. The Quatio comes with three sets of nozzles: the Gold Nozzle gives you a clear, neutral, and accurate sound; the Silver Nozzle offers a balanced sound; and the Black Nozzle provides a warmer and smoother listening experience. This makes it easy to find the sound that suits your taste.

PREMIUM CNC-MACHINED ALUMINUM SHELLS FOR DURABILITY AND COMFORT

Kefine is well-known for making IEMs with excellent build quality, and the Quatio is no exception. Each earpiece is made from high-quality aluminium alloy using precise CNC machining, which takes over 30 minutes per pair. The manufacturing process is so accurate that the size difference between pairs is less than 0.01mm. After machining, the earpieces are carefully polished and anodized to give them a smooth, premium finish. The metal housing is very thin—only 0.06mm thick—making the shells compact and comfortable to wear for most people.

HIGH-PURITY SILVER-PLATED CABLE WITH MODULAR PLUGS

The wired in ear monitor includes a high-quality, silver-plated oxygen-free copper cable. This cable is made up of four braided strands, and each strand contains 98 individual wires, adding up to a total of 392 wire cores. This design helps deliver a clean and lossless sound signal. The cable also features a swappable plug system, allowing you to easily switch between 3.5mm and 4.4mm plugs, both of which are included in the package.
