Hear Every Detail, Feel Every Note

The Kiwi Ears Halcyon is the world's first MEMS + 1DD + 3BA tribrid IEM, combining cutting-edge MEMS technology with a dynamic driver and custom balanced armatures for full-spectrum sound. CNC-milled aluminum housings and precision acoustic engineering deliver wide soundstage, clear mids, deep bass, and sparkling trebles. Optional USB-C DAC cable with DSP allows fully customizable EQ for a personalized listening experience.

MEMS Technology Meets Tribrid Setup

The Halcyon is one of the first in-ear monitors to implement a tribrid configuration utilizing cutting-edge solid-state MEMS (Micro-Electro-Mechanical Systems) technology. MEMS is a solid-state speaker using silicon chips and passive components to generate a piezoelectric effect. Without traditional acoustic components such as coils and diaphragms, MEMS excels in speed and high-resolution performance, particularly in the ultra-treble frequencies. Combined with traditional balanced armature and dynamic drivers, Halcyon achieves one of the world’s first tribrid configurations to benefit from MEMS’ ultra resolution.

Best-In-Class Tonal Signature

The Halcyon combines technical performance with exceptional tonal balance. Following Kiwi Ear’s famed tonal signature, the Halcyon provides a studio monitor-like neutral tuning with an enhanced sub-bass boost. The sub-bass shelf features a balanced 8dB sub-bass boost, which is cleanly cut at 200Hz for bloat-free midrange. The mids are natural and clean, mirroring the accuracy of studio monitors. This enhances instruments and vocals and provides exceptional imaging and layering precision. The treble peaks precisely at 3kHz for a perfect pinna gain compensation, and has a treble decay that is fitted to modern tuning preference signatures.

Excellence in Driver Technology

The Halcyon combines the best of both traditional and modern driver technologies. A 10mm composite diaphragm dynamic driver powers the sub-bass for a powerful, yet well-controlled and tight bass response. This provides a real subwoofer-like bass experience, while keeping the midrange clean and free from discoloration. The midrange is powered by two DEK-series custom balanced armature drivers, specifically tuned to give a natural tonal balance to instruments and vocals. The trebles are fitted with a custom WBFK-series balanced armature tweeter, which is paired with Kiwi Ear’s MEMS driver to achieve ultra-high resolution.

USB-C Cable with Custom DSP Equalization

The Halcyon comes with a 2-pin connector system, which allows modularity with other 2-pin connector cables. Moreover, a USB-C cable is available, with an embedded custom DSP equalization. Combined with Halcyon’s app, users can adjust the EQ to fit their own preferred tuning profile.

Ultimate Versatility for Audiophiles and Gamers

Designed for professionals, audiophiles, and gamers alike, the Halcyon is a versatile powerhouse. Its neutral tuning and precise imaging make it ideal for studio monitoring, while the optional gaming boom mic cable ensures pure, crystal-clear communications during intense matches or video calls. Crafted with an aerospace-grade aluminum body, it provides the durability and ergonomic comfort needed for long sessions, no matter the environment.
