Michelle Limited

A true collaboration between Astell&Kern and Jerry Harvey Audio.

Michelle Limited is based on professional sound technology from Jerry Harvey Audio, a well-known leader in the custom earphone industry.
An extension of the existing Siren series, which is loved by audiophiles around the world, Michelle Limited is a product that people who love music can enjoy at an affordable price.

Jerry Harvey Audio Freqphase, a patented technology, 3Way 3Drivers, Ergonomic Unit and Silver Tinsel cable are all utilized for improved sound quality.

Recognized by world-leading custom earpiece founder Jerry Harvey Audio and worldwide audiophiles, Michelle Limited is the link between music and music lovers.

Michelle Limited is the amalgam of all we have learned in the development of the industry leading Layla and Roxanne. Our goal was to utilize as much of our new technology into an IEM at a more affordable price. The wide frequency response coupled with use of FreqPhase technology makes for a very accurate Universal IEM. The Michelle Limited has the top end extension, as well as powerful low end of IEMs that cost twice as much.

Michelle Limited Technology



Jerry Harvey Audio has developed a whole new Balanced Armature Driver to offer Reference quality IEMs for Mastering and mixing works. The high-range drivers are designed to deliver everything with minimum distortion, the ultimate mid driver offers perfect, flat sound from 10Hz to 5kHz.

The bass driver was designed for an even steeper Low-pass effect with no distortion.

Freqphase™ Time | Phase Waveguide

Most Multiple Driver IEM’s suffer from phase and timing issues. Low, Mid, and High drivers all have different impulse times. The higher it is, the faster the impulse time of the BA Driver. The lower it is, the slower the response speed. This causes improper arrival times and Phase shifts.

The “Michelle Limited” applies Jerry Harvey Audio’s patented “FreqPhase” technology, which uses precisely cut tube lengths for each driver to minimize the phase shift of each frequency. This allows for the High, Mid, and Low drivers to be aligned to 1/100ms for the most ideal Phase curve. It ensures the correct time alignment and phase of all drivers resulting the most accurate music reproduction in the industry.

3Way 3BA Drivers

Michelle’s balanced amateur driver boasts a much smaller size and amazing efficiency compared to conventional dynamic drivers. Enjoy the full range of sonic details, thanks to the sophisticated 3 balanced amateur driver design, fused with FregPhase technology.


Ergonomic Shell Design

A proper "seal" is essential to the the performance of any universal IEM.

The design of the "Michelle Limited" is the result of an exhaustive research and development project on the ergonomics of IEM fit.

Michelle Limited adopted the perfect angle and size for optimum contact with the ear and comfortable fit for the best sound quality and listening pleasure.

The "Michelle Limited's" performance now shares the performance characteristics of IEMs costing three times as much.

Silver Tinsel Cable with detachable 2pin connector

The cable used in the Michelle is not common copper. Instead, it is a copper cable plated with silver. The cable is manufactured by first compressing the silver plated copper wire, which is then flattened and rolled into a steady interval that is then used to wrap around the Kevlar*. This newly developed cable has astounding tensile strength and delivers the full dynamic range of music. There are two different types of cables provided - a 3.5mm Unbalanced and 2.5mm Balanced cable.

Conventional straight cables do not handle the frequent bending of cables and often short out. The intertwined cable disperses the stress to the cable and offers better resilience. It’s also easier to wear around the outer ears as the cable shape can be easily adjusted for the best fit.

* Kevlar - The brand name of Aramid fiber that DuPont USA manufactured. It is very lightweight and more durable than nylon, and has the advantage of being very tough. Because it is made of light weight organic polymers such as carbon, nitrogen and hydrogen, allowing it to be 5 times more stronger than steel. Kevlar is particularly strong against friction and is commonly used for body armor and aircraft tires due to its excellent shock absorption.
