Product Information

Michelle Limited

The Michelle Limited, a special edition product produced in Korea, is the result of a dedicated collaboration between Astell & Kern, a universally respected audio technology company, and Jerry Harvey Audio, an industry leader in customized earphones.

Expanding beyond the existing Siren series, which is loved by audiophiles worldwide, Michelle Limited lets more price-conscious listeners experience the rich, vivid sounds Astell & Kern and Jerry Harvey Audio are known for.

The Michelle Limited features freqphase, a patented technology of Jerry Harvey Audio, adopted 3-way 3-driver to deliver all ranges of sound with units designed for authentic sound reproduction, and the silver cable for clear, crisp audio quality.

Market-proven technologies from Astell & Kern coupled with the experience of Jerry Harvey Audio, a trailblazer in the custom earphones industry, created the Michelle Limited to connect audiophiles everywhere.

The Siren Series

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, while 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.

3-Way 3BA Drivers

The Michelle Limited’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 Freqphase 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. The 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. Its performance now shares the performance characteristics of IEMs costing three times as much.

Silver Tinsel Cable with Detachable 2-Pin Connector

The cable used in the Michelle is not common copper. Instead, it is a copper cable plated with silver. It's 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.


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.

awesome sound for the price point
I'm an avid fan of etymotic headphone sound , but do not like placing them into my ear canal so far down. This is the answer for those who want a more comfortable fit with out compromising a lot of sound quality.

I would recommended these.
