Kiwi Ears - Astral In-Ear Headphone IEM
1DD+6BA Hybrid IEM
Kiwi Ears Astral combines a 10mm bioceramic dynamic driver with six balanced armature drivers to deliver an impeccably balanced audio signature. It offers a controlled sub-bass that merges smoothly into a clear midrange and refined treble, ensuring every detail is faithfully reproduced.
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.
Powered by our innovative 1DD+6BA hybrid design, the Astral is built for listeners who value precision and truth in sound. Thoughtfully engineered and finely tuned, it unveils the subtleties of every track for an experience that feels refreshingly real.
The Astral is Kiwi Ear’s professional-grade in-ear monitor, engineered for music professionals and discerning audiophiles alike. It delivers premium audio resolution with exceptional tonal balance, ensuring an engaging listening experience without compromising accuracy or precision.

At the heart of the Astral is an in-house 10mm bioceramic diaphragm dynamic driver. This custom-designed driver offers an excellent low-end thump, smoothly transitioning into lush bass. With a carefully tuned bass response and a gentle roll-off at 300Hz, it seamlessly bridges the gap between the bass and midrange frequencies for a natural, dynamic performance.

Complementing the dynamic driver, the Astral incorporates two dual midrange balanced armature drivers alongside a dual ultra-high frequency tweeter. These in-house custom midrange drivers focus on delivering a neutral sound profile for vocals and instruments, enhanced by an accurately compensated pinna curvature at 2.8kHz. The tweeter, modified from the renowned SWFK design, extends treble response smoothly, ensuring a uniform and natural ultra-treble without any harshness.

The Astral redefines Kiwi Ears’ tonal profile with its distinctive sound signature. Featuring a powerful 9dB sub-bass shelf, it transitions gracefully into the low-midrange, with a cutoff at 300Hz that allows for a natural bass roll-off. This design preserves a flat, neutral midrange that blends perfectly with the bass. Additionally, the carefully sculpted treble peaks at 2.8kHz and rolls off uniformly until 15kHz, adding sparkle, airiness, and an expansive stage presence that elevates the overall listening experience.
