Product Information

JAYS' Most Precise Instrument Made to Date

Made with the intention of crafting the world’s finest earphones, q-JAYS Reference Audio Only Earphones are built to deliver the most authentic and detailed sound experience possible. Their 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.

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 their small form factor, JAYS has managed to implement reliable, custom-made threaded connectors in each housing. With options for dedicated cable modules for Audio Only (without remote box), iOS, Windows, or Android, choose the solution that best fits your needs and enjoy a pair of earphones that last longer.

Solid Stainless Steel for Durability

Bigger isn’t always better. The 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 matte, proprietary, scratch-resistant, anti-fingerprint coating gives the q-JAYS their charcoal black look.

A New Reference

q-JAYS is by far the most precise instrument JAYS has made to date, with every single part precisely manufactured from the best-suited premium materials. At its core is their 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 JAYS to create one of the most precise and finely toleranced earphones ever made, while keeping it impressively small.

Physical Vapor Deposition Process

The stainless steel parts are completed by applying a proprietary Physical Vapor Deposition modification to the 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 a molecular level to create their signature solid matt black, scratch-resistant surface.

  • First, the q-JAYS' curved one-piece body is created by Metal Injection Molding and sintering solid stainless steel parts, followed by precise CNC machining.
  • Secondly, the stainless steel part is subjected to industry-grade polishing to achieve a smooth and reflective finish.
  • The part is then put through a sandblasting process to create its rugged, easy-to-hold, and grease-resistant surface.
  • The process is completed by applying a proprietary Physical Vapor Deposition modification, creating the matte 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, the q-JAYS' tailor-made acoustic filter washes off any sharp sibilance, leaving clean and smooth highs with stunning details.

Reference Class Sound Signature

You’ll be amazed by the incredible clarity and resolution of the q-JAYS' sound. With stunningly rich details, perfect timbre, and astonishing balance, the 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

The 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 efficient at dirt protection, and they ensure fully transparent acoustic properties.

Precisely Tuned Bass Ports

As part of the acoustic system, the q-JAYS' stainless steel housing feature a precisely tuned vent port that 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 a 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

The 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 JAYS 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 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 remotes using the latest MEMS microphone technology that allows you to experience amazing, crystal-clear speech quality with built-in echo cancellation and noise reduction.

High-Purity Copper and Kevlar Cables

The brand new cable formula includes high-purity copper, Kevlar reinforced isolation, and soft flexible TPE coating for excellent audio performance and high durability.

Durable L-Plug

The newly engineered L-plug raises the bar even further in terms of performance. It has passed JAYS' toughest reliability tests to date.


q-JAYS come with a range of useful accessories. Choose from 5 sizes of silicone ear tips, or the Comply Foam Ear Tips. These tips effectively isolate noise by using your ear canal as a sealed acoustic bass chamber. When not in use, the JAYS protective case offers your q-JAYS protection from scratches, dust, and moisture.

Great things come in small packages
Unbelievable sound stage! Fantastic presence! Much better fit and sound than my RHA 750. Unfortunately, I was involved in an industrial accident and the cord was destroyed...but not the iems themselves. Patiently waiting for my replacements.
