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 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.

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.
