Professional Design and Performance: The Kiwi Ears Astral is a high-end in-ear monitor developed for music professionals and astute audiophiles. It is engineered to deliver accurate audio resolution and a balanced tonal response. The design focuses on clarity and precision, ensuring that each component works together for faithful sound reproduction.

Dynamic Driver Subwoofer: The Astral features a 10mm bioceramic diaphragm dynamic driver designed to reproduce low sub-bass frequencies. The driver produces a firm sub-bass thump that transitions smoothly into the bass range. The tuning of the bass includes a rolling cutoff at 300Hz to allow a natural flow into the midrange.

Balanced Armature Driver System: The device incorporates six balanced armature drivers, arranged as two dual midrange drivers and a dual ultra-high frequency tweeter. The custom midrange drivers are designed to provide a neutral frequency response with a specific emphasis at 2.8kHz to match natural hearing. The tweeter has been modified to achieve a smoother ultra-frequency response that integrates seamlessly with the midrange.

Tonal Signature and Tuning: The tonal profile of the Astral features a 9dB sub-bass shelf that transitions into the low-midrange with a cutoff at 300Hz. This design maintains a flat and neutral midrange, ensuring accurate sound reproduction. The treble is defined by a peak at 2.8kHz, which gradually rolls off up to 15kHz, extending the upper frequency range while avoiding harshness.
