Astell & Kern Michelle

Jerry Harvey Audio x Astell&kern

Michelle, the fifth Universal In-Ear Monitor in the SIREN SERIES line, is born from Jerry Harvey's over 20 years of experence designing Custom IEM's that have become the choice of the biggest touring artists in the world. These are the very people who create the music that we all listen to every day.

Michelle features Jerry Harvey Audio's patented FreqPhase technology, three specially designed Balanced Armature Drivers for full dynamic range, newly designed ergonomically shaped 3D printed shells, and Silver Tinsel cable are all part of this affordable but powerful package. The result is, "Michelle" another great collaboration between Jerry Harvey Audio and Astell&Kern, These two renowned companies continue to lead the industry and now bring their highest end performance to a unprecedented affordable price for music lovers all over the world.

The fifth in the Siren Series, Michelle, derives its name from the Guns N' Roses song 'My Michelle'. 'My Michelle' was featured in Guns N Roses debut studio album, 'Appetite for Destruction', in dedication to the lead guitarist Slash's friend Michelle Young. Michelle had always wanted someone to write a song that contained her story. 'My Michelle' represents Michelle's life in its entirety, from her drug addiction to her mother's death, and even her father's time in the adult entertainment business. In his autobiography, Slash explains how Michelle abandoned her old life and successfully started a new life after the release of the song.

Michelle 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 has the top end extension, as well as powerful low end of IEMs that cost twice as much.

Michelle Technology

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, 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" 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 Freqphase technology.

Ergonomic Shell design with 3D printing technology

A proper "seal" is essential to the the performance of any universal IEM.
The design of the "Michelle" represents an exhaustive research and development project on the ergonomics of IEM fit.
The new state of the art 3D printed shell gives "Michelle" an advanced fit that represents a significant breakthrough on IEM shell shape and the angle of the nozzle, resulting in unprecedented comfort and acoustic seal.

The "Michelle's" performance now shares the performance characteristics of IEMs costing 3 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.

Hand Crafted IEM

Most Universal IEMs at this price point are mass manufactured to keep cost down. Instead we chose to use the very same methods we use to build custom IEMs costing 4 times as much as the "Michelle". Everything is measured out to the smallest detail from the first step to the last one –3D printing the shell, matching the drivers, tube lengths, and testing to match phase and reference freq curves within 1dB. This method takes a bit longer than mass manufacturing, but the extra care results in a hand crafted masterpiece produced by expertly skilled technicians.
