A&K Diana Earphones, by Jerry Harvey Audio

Beautiful both inside and out, Diana is a product created by combining the world-renowned IEM technology of Jerry Harvey Audio, and the expertise of Astell&Kern reputed for their quality Korean-made products.

Like the Full Metal Jacket Siren Series, which is loved by music enthusiasts around the world, A&K have created Diana, crafted out of a full metal shell to produce a world-class level IEM in terms of both sound and design.

Diana features the patented Freqphase from Jerry Harvey Audio and the same sound bore design applied to the Billie Jean earphones. Its impeccably beautiful full metal shell made from aluminium with great precision not only delivers a visually impressive image but also makes the sound more solid so you enjoy the most ideal sound without distortion in all sound ranges.

All features - including the 3-way x3 drivers, optimized size, silver tinsel and anaerobic copper cables used in high-end top cables - come together to provide outstanding sound that cannot be matched in existing IEM products.

Created by Jerry Harvey Audio, the inventor of the world’s leading custom earphone and Astell&Kern the favorite of music enthusiasts around the world, Diana lets you enjoy its beautiful design and amazing sound at the same time.


Technology

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, 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.

Freqphase™ Time | Phase Waveguide - Most multi-driver IEM's suffer from phase and timing issues. The low, mid, and high drivers all have different impulse times. The higher it is, the faster the impulse time. The lower it is, the slower the response speed. This causes improper arrival times and phase shifts. Diana 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 all drivers to be aligned to 1/100ms - delivering the most ideal phase curve, ensuring correct time alignment and phase, and resulting in the most accurate music reproduction currently available.

3-Way 3-BA Drivers - The balanced armature (BA) drivers used in Diana are smaller and incredibly more efficient than conventional dynamic drivers. Three BA drivers with optimized tuning are elaborately designed and integrated with Freqphase, Timephase, and Waveguide technologies which deliver crystal clear sound in all sound ranges. In particular, the Acoustic Chamber Sound Bore design of Jerry Harvey Audio has been crafted and applied to Diana. This design creates the full amount of air needed to deliver sound, making it more optimized for treble. It also prevents sweat and dirt from accumulating in the sound bore.

High Quality Full Metal Shell - Diana’s sleek design is carefully crafted from aluminium through multiple steps. The design flowing from the Sound Bore, body, to the logo on the shell boasts excellent durability, as strong as it is beautiful and light. Capturing all the experience and know-how of Jerry Harvey Audio’s Custom IEMs, the universal fit Diana offers the best fit and comfort for audiophiles everywhere.

4N pure silver and 7N OCC copper hybrid 2.5mm 4-pole cable - Included with, designed and tuned especially for the Astell&Kern Diana is a very special headphone cable; an 8-conductor wire of awesome sound. Made with 4N pure silver with silver plated 7N OCC to deliver the high in this combination; and the 7N OCC to bring the low.
