Shaped for a Precise Fit

Billie Jean is over 30% smaller compared to Michelle Limited. Its design has been optimized after a series of studies of different shapes of ear canals from both men and women of different ages. It fits and sits perfectly in your ears without bulkiness. The Universal Fit Billie Jean is the perfect companion for Pro Audio applications such as sound monitoring. With the noise isolation design and the IEM know-how from Jerry Harvey Audio, you will get the best fit and comfort while you enjoy your tunes in a new way.

Detachable Silver Tinsel Cable

The cable used in the Billie Jean 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 is a 3.5mm Unbalanced cable provided. 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.
