Michelle, the fifth Universal In-Ear Monitor in the SIREN SERIES line, is born from Jerry Harvey's over 20 years of experience in 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. The 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, which are all part of this affordable but powerful package. Michelle's Balanced Armature 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 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. 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. 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.
