A true collaboration between Astell&Kern and Jerry Harvey Audio. Michelle Limited is based on professional sound technology from Jerry Harvey Audio, a well-known leader in the custom earphone industry. An extension of the existing Siren series, which is loved by audiophiles around the world, Michelle Limited is a product that people who love music can enjoy at an affordable price. Jerry Harvey Audio Freqphase, a patented technology, 3Way 3Drivers, Ergonomic Unit and Silver Tinsel cable are all utilized for improved sound quality. Recognized by world-leading custom earpiece founder Jerry Harvey Audio and worldwide audiophiles, Michelle Limited is the link between music and music lovers. 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. 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 Limited” 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. 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 FregPhase technology. A proper ''seal'' is essential to the the performance of any universal IEM. The design of the ''Michelle Limited'' is the result of an exhaustive research and development project on the ergonomics of IEM fit. Michelle Limited adopted the perfect angle and size for optimum contact with the ear and comfortable fit for the best sound quality and listening pleasure. The ''Michelle Limited's'' performance now shares the performance characteristics of IEMs costing three times as much. Colour: Black.
