Our finest achievement

Made with the intention of crafting the world’s finest earphones, q-JAYS is built to deliver the most authentic and detailed sound experience possible. Its perfect timbre and high-resolution details were made possible by integrating advanced audio engineering with various state-of-the-art development techniques such as Metal Injection Molding, CNC and laser cutting. This is q-JAYS, our finest and most precise achievement till date.

Two speakers in each side

Engineered like a set of reference loudspeaker monitors, q-JAYS feature dual speakers built into each side, one for low frequencies and one for midrange and highs. Each speaker renders its dedicated frequency spectrums relaxed and naturally reproducing perfectly accurate tones. Thanks to its custom drivers and a new crossover filter, you will enjoy a seamless frequency response without irregularities often found in many larger multiple driver systems.

Exchangeable cables for longer life

q-JAYS are the world’s smallest earphones made with exchangeable cables. Despite its small form factor, we have managed to implement reliable, custom-made threaded connectors in each housing. With options for dedicated 3.5mm connector cable modules for Audio Only (without remote box), iOS, Windows or Android, choose the solution that best fits your needs and get to enjoy a pair of earphones that last longer.

Solid stainless steel for durability

Bigger isn’t always better. q-JAYS housing is designed to be remarkably small and sturdy. The durable and precisely manufactured fine-tolerance stainless steel housing brings out every last detail of the drivers with absolute accuracy. A matt proprietary scratch-resistant anti-fingerprint coating gives the q-JAYS their charcoal black look.

Certified high-resolution earphones

q-JAYS Reference earphones has been certified by the Japan Audio Society as Hi-Res Audio instruments. The certificate is a seal of quality, awarding products capable of reproducing the fine details in Hi-Res Audio, which for digital audio is from 24bit/96kHz and above.

High-frequency bandwidth to 40kHz

The q-JAYS are able to reproduce an incredible amount of resolution and fine details throughout the entire frequency range. q-JAYS, with its high dynamic range, are also capable of unveiling the subtle details in the high frequency bandwidth up to 40 000 Hz and above. Reclaim the music and hear what you’ve been missing.

Measuring full performance

Measuring in-ear earphones using ear simulators give a realistic portrait of what we are hearing, however the method is usually unable to detect frequencies above 20 000 Hz. By using Hi-Res microphones and measuring earphones in free space, higher frequencies can be detected and the earphones’ full performance measured.

Check out our Anniversary edition

Made in stainless steel, with a slightly sooty, reflective steel finish, crafted by eight additonal rigorous polishing procedures on top of the industry grade polishing. It’s also accompanied with a newly developed set of twisted, high-purity, oxygen-free copper cables for enhanced audio signal transmission.

Available for USD 349 in 200 numbered limited edition sets only.

A new reference

q-JAYS is by far the most precise instrument we have made till date, with every single part precisely manufactured from the best suited premium materials. At its core is our brand new acoustic system with custom balanced armatures and tailor-made acoustic filters. Perfectly tuned with the fine-tolerance solid stainless steel housing, q-JAYS is where finest audio performance meets outstanding quality and unbeatable ergonomics.

Metal injection molded stainless steel

Built to last and engineered for precision, q-JAYS curved solid one-piece housing is made by metal injection molding stainless steel. This, along with CNC machining and laser-cutting allowed us to create one of the most precise and finely toleranced earphones ever made, while keeping it impressively small.

Physical Vapor Deposition

The stainless steel parts are completed by applying a proprietary Physical Vapor Deposition modification to q-JAYS surface finish. This is one of the toughest coatings in the industry, which binds vaporized metal particles with the stainless steel surface on molecular level to create its signature solid matt black, scratch-resistant surface.

1. Metal injection

First, q-JAYS curved one-piece body is created by Metal Injection Molding and sintering solid stainless steel parts, followed by precise CNC machining.

2. Polishing

Secondly, the stainless steel part is subjected to industry grade polishing to achieve a smooth and reflective finish.

3. Sandblasting

The part is then put through a sandblasting process to create its rugged, easy-to-hold and grease-resistant surface.

4. Physical Vapor Deposition

The process is completed by applying a proprietary Physical Vapor Deposition modification, creating the matt black, scratch-resistant finish; one of the toughest coatings in the industry.


Dual balanced armature drivers

JAYS custom dual balanced armatures are one of the world’s most precise, advanced and smallest two-driver system for authentic audio reproduction. A brand new crossover filter seamlessly blends the output of the dedicated woofer driver with the midrange/tweeter driver, free from time and phase shifts, resulting in a well-balanced sound with incredible clarity, high-transient speed and timing.

Tailor-made acoustic filters

Positioned inside the sound tube and in front of the balanced armatures as a part of the acoustic system, q-JAYS tailor-made acoustic filter washes off any sharp sibilance, leaving clean and smooth highs with stunning details.

Frequency response measured with G.R.A.S ear simulator

Reference class sound signature

You’ll be amazed by the incredible clarity and resolution of q-JAYS sound. With stunningly rich details, perfect timbre and astonishing balance, q-JAYS render one of the most precise and authentic sound reproductions with minimal coloration. Get ready to rediscover and experience your favorite music all over again from a new frame of reference.

Removable, laser-cut protective filters

q-JAYS feature threaded, removable and easy to clean filters machined from solid aluminum with 55 precise laser-cut holes within a two millimeter diameter area. These protective filters are extremely strong due to its honeycomb-like structure, efficient at dirt protection, while ensuring fully transparent acoustic properties.

Precisely tuned bass ports

As part of the acoustic system, the q-JAYS stainless steel housing features a precisely tuned vent port which completely opens up the lows below 200 Hz, providing the dedicated woofer with enough air volume for optimal performance. The result is a tight, rapid and deep bass response without affecting any of the other frequencies.

World’s smallest earphones

The legacy has continued with this second generation of q-JAYS — now the world’s smallest earphones with exchangeable cables. The emphasis on exceptional sound experiences while keeping its small size has led to several innovations and improvements including: an incomparably precise brand new acoustic system, stainless steel housing, removable protective filters, and custom threaded connectors.

Custom-made threaded connectors

q-JAYS Custom SSMCX connectors are among the smallest in the world. Machined with durable threading and gold-plating, these micro-sized connectors made it possible for us to create exchangeable cable modules that increase both q-JAYS lifespan and flexibility of use. Furthermore, the threaded interface creates a durable, glitch-free fit with infinite conductivity.

Two-way wear

Depending on your preference, you can use your q-JAYS in two ways: with the cable going straight down, or with the cable positioned behind your ear, which also helps prevent microphonics. The exchangeable cables ensure that you get the correct stereo imaging even after switching the earphones.

iWA modules for every phone

q-JAYS have a wide range of cable module options available, including remote and mic solutions for iOS, Windows and Android devices. All come with full-feature three-button remote using the latest MEMS microphone technology that allows you to experience amazing, crystal-clear speech quality with built-in echo cancellation and noise reduction.
