Astell & Kern Diana

Superb aluminium shell in-ear monitors at a great price

Diana is a universal fit Siren Series In-Ear Monitor developed by Jerry Harvey Audio and manufactured in-house by Astell&Kern.  Diana features Jerry Harvey’s patented Freqphase technology, with a new sound bore design first developed and adapted for the Billie Jean IEMs.

With a beautiful, full metal shell made in aluminum, Diana not only delivers a visually impressive design, but also produces a more solid sound profile that allows the listener to enjoy the most ideal sound without distortion across all sound ranges.

Diana features a 3-way, 3-driver design that provides a dedicated single high, single mid-range and single low balanced armature per channel for best sound reproduction.  Jerry Harvey developed a whole new Balanced Armature Driver for Diana designed to offer Reference quality IEMs for Mastering and mixing works. The high-range drivers are designed to deliver everything with minimum distortion, while the 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.

Also included with the Diana is an all-new 2-pin 2.5mm balanced cable first developed for the AK T5p 2nd Generation headphones.  The cable is made with 4N pure silver with silver plated 7N OCC to deliver the perfect highs; and the 7N OCC to bring out the lows. This hybrid construction of pure silver, silver OCC and OCC litz cable creates a unique harmony and is the finishing touch to both the AK T5p headphones and Diana IEMs. No more sharp highs or too much bass, you achieve the perfect balance to your music with this unique cable.

Additional accessories include a 2.5mm to 3.5mm adapter, silicon ear tips (small, medium and large) and a carrying case.

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 “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 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.

3-Way 3-BA Drivers

The balanced armature drivers used in Diana are smaller and incredibly more efficient than conventional dynamic drivers. Three balanced armature 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.

Experience Diana and hear music at its finest.

The cable included with – and designed and tuned especially for
– the Astell&Kern Diana is a very special headphone cable – an 8-conductor wire of awesome sound.
It’s 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.
This hybrid construction of pure silver, silver OCC and OCC litz creates a unique harmony and is the finishing
touch to Diana’s excellence. No more sharp highs or too much bass: bring perfect balance to your music with this unique cable.
