Astell&Kern x JH Audio Diana – High-end in-ear monitors for audiophile perfection

Reference sound born from the collaboration of two high-end specialists

The Astell&Kern x JH Audio Diana combines Jerry Harvey Audio's decades of experience in professional in-ear monitoring with Astell&Kern's uncompromising audio expertise. The result is an exclusive high-end in-ear monitor that combines exceptional sound quality, cutting-edge driver technology, and a premium aluminum housing in an elegant design.

Developed for audiophiles and discerning music lovers, the Diana impresses with an exceptionally natural reproduction, impressive detail resolution, and a precise spatial imaging.

Three balanced armature drivers for maximum precision

Inside the Diana are three perfectly tuned balanced armature drivers, each optimized for bass, midrange, and treble frequencies.

This specially developed 3-way design delivers powerful, controlled bass, finely resolved mids, and brilliant highs – free from distortion and with exceptional dynamics across the entire frequency spectrum.

Freqphase™ – Perfect time and phase alignment

A special highlight is the patented Freqphase™ technology from Jerry Harvey Audio.

While conventional multi-way in-ears often suffer from drivers working out of sync, Freqphase synchronizes all frequency ranges to within 1/100th of a millisecond. Individually calculated sound bores ensure that high, mid, and low frequencies arrive at the ear in perfect phase alignment.

The result is an exceptionally precise sound image with realistic spaciousness, exact instrument placement, and impressive naturalness.

Optimized acoustic chamber for clean highs

Jerry Harvey Audio's specially developed acoustic chamber significantly improves treble performance.

It extends the frequency range, ensures more uniform high-frequency radiation, and simultaneously prevents sweat or earwax from entering the sound bores. This ensures that the sound quality remains at the highest level over the long term.

High-quality aluminum housing

The Diana features a precision-crafted solid aluminum housing that combines maximum stability with light weight.

In addition to its exceptional durability, the low-resonance housing reduces unwanted vibrations, supporting a natural sound reproduction. At the same time, the ergonomic design ensures a secure and comfortable fit – even during long listening sessions.

Designed for maximum comfort

The shape of the housing is based on years of research into the anatomy of the human ear canal.

Thanks to Jerry Harvey Audio's experience in custom in-ear monitors, the universal fit of the Diana offers an outstanding seal and high comfort for a wide variety of ear shapes.

High-quality hybrid headphone cable

Included in the scope of delivery is a specially developed 8-core hybrid cable that has been perfectly matched to the Diana.

It combines:

• 4N pure silver

• Silver-plated 7N OCC copper

• High-purity 7N OCC copper

This material combination ensures particularly fast signal transmission, the finest detail resolution, and a balanced harmony between powerful bass, natural mids, and silky highs.

The high-quality 2.5 mm 4-pole connector enables balanced signal transmission and maximizes the performance of modern high-end music players from Astell&Kern.
