Billie Jean brings to life a real audio experience that will take your music to the next level.
Utilizing our experience of producing the award-winning SIREN Series IEMs, which is loved by music enthusiasts around the world, we were able to achieve a new level of accomplishment for those who enjoy a genuine music experience.
Billie Jean features the patented freqphase® technology from Jerry Harvey Audio with a new internal sound bore design to bring clear and impeccably balanced sound from sub-bass to brilliance range. The new IEM shell has been optimized to fit nicely in the ear, utilizes a 2-way 2-BA design, Silver Tinsel cable and L-type plug in a small, compact package. The result is a brilliant pair of IEMs designed and built by Jerry Harvey, the inventor of custom-IEMs, and Astell&Kern, the global leader in Hi-Fi audio.

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.
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 "Billie Jean" 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.
The Balanced Armature drivers used in Billie Jean are a customized BA only available from Jerry Harvey Audio and is designed to bring more power with less weight. Billie Jean will surprise you with efficient, yet powerful sound.
Jerry Harvey Audio’s Freqphase®, Timephase, and Waveguide technologies allow this 2-way 2-BA IEM to deliver the full range of audio performance anytime.
The special Acoustic Chamber Sound Bore design has been carefully crafted to bring a wide soundstage with incomparable dynamic range, without adding any interference.
We highly recommend you try Billie Jean with your favorite tunes, which will never sound the same again.
