Astell&Kern and Jerry Harvey Audio

Billie Jean brings real audio to life, taking music to the next level. With the experience of producing the award-winning Siren Series IEMs, loved by music enthusiasts worldwide, the Billie Jean offers audiophiles a genuine music experience

The Siren Series

Having developed a Balanced Armature Driver, Jerry Harvey Audio offers reference quality IEMs for mastering and mixing works. While the high-range drivers are designed to deliver sound with minimum distortion, the ultimate mid driver offers a crisp, flat sound from 10Hz to 5kHz. The bass driver is designed for a steeper, low-pass effect, without distortion.

Freqphase Technology

With Jerry Harvey's Freqphase technology, Billie Jean uses precisely cut tube lengths for each driver. This minimises the phase shift of each frequency, allowing for the High, Mid and Low drivers to be aligned to 1/100ms for the ideal phase curve. This ensures the correct time alignment and phase of all drivers, resulting in the most accurate music reproduction in the industry.

2-Way Dual Balanced Armature

With 2-Way Dual Balanced Armature drivers unique to Jerry Harvey Audio, the Billie Jean brings more power with less weight. Paired with Jerry Harvey Audio's Freqphase, Timephase and Waveguide technologies, this 2-Way 2-BA IEM delivers the full range of audio performance - the Billie Jean will surprise you with efficient, yet powerful sound.

Silver Tinsel Cable

The silver-plated copper cable used for the Billie Jean is created by flattening silver plated copper wire and wrapping it around Kevlar. This created a cable that has an astounding tensile strength, whilst delivering the full dynamic range of music. The intertwined cable is also easier to wear around the outer ear.

Universal Fit

Over 30% smaller than the Michelle Limited IEM, the Billie Jean has been designed with a universal fit for comfort, without bulkiness. The Billie Jean is the perfect companion for Pro Audio applications - such as sound monitoring. With noise-isolation and Jerry Harvey's IEM know-how, get the best fit whilst enjoying quality audio.
