A New Era of Hybrid Design
Nautic Stellar adopts a sophisticated quad-hybrid, 8-driver configuration that brings out the full spectrum of musical expression with pinpoint accuracy and tonal richness.
- Low Frequencies: 10mm silk diaphragm dynamic driver
- Midrange: 4x balanced armature drivers
- High Frequencies: 6mm nano-diaphragm planar driver
- Full-Range Enhancement: 2x Sonion bone conduction drivers
Each driver type contributes a distinct sonic character. The dynamic driver grounds the sound with warmth and punch, the balanced armatures deliver clarity and definition, the planar unit adds treble smoothness and precision, while bone conduction enhances spatial realism and micro-detail.
Full-Bodied Bass with Natural Texture
At the heart of Nautic Stellar’s low-end is a 10mm silk diaphragm dynamic driver. Designed for both scale and subtlety, the driver leverages the lightweight, elastic nature of silk to produce a bass response that is full, textured, and naturally resonant — ideal for acoustic instruments and rhythmically complex passages.
Refined and Layered Midrange
To ensure depth and realism in the midrange, Jomo Audio incorporates two open-vented balanced armature drivers, allowing increased airflow and enhanced articulation. These are supported by re-tuned Sonion bone conduction drivers that provide subtle resonance and ambient cues, resulting in a midrange that is three-dimensional, lifelike, and emotionally engaging.
Precision Crossover and Pure Signal Flow
A custom-designed crossover circuit ensures that each driver operates within its optimal frequency range, enhancing clarity and preserving tonal balance. Internally, Jomo utilizes high-purity 6N silver wiring, ensuring pristine signal transmission and allowing the full resolution of each driver to be realized without coloration.
3D-Printed Acoustic Architecture
The internal layout of Nautic Stellar utilizes a custom 3D-printed acoustic chamber that houses the dynamic, planar, and balanced armature drivers. This structure minimizes unwanted resonances, aligns acoustic phases, and ensures consistent sound projection from a centralized point — resulting in superior imaging and spatial cohesion.
Crafted with Watchmaking Precision — 904L Stainless Steel
The shell of the Nautic Stellar is milled from 904L stainless steel, a high-grade alloy favored by luxury watchmakers for its superior corrosion resistance, rigidity, and mirror-like polish. Each shell is CNC-machined with 5-axis precision and meticulously hand-polished to achieve a refined, heirloom-quality finish.
The faceplate continues Jomo’s tradition of layered design, featuring a multi-tiered openwork layout inspired by cosmic geometry. Master artisans manually engrave wave and solar motifs using traditional engine-turning techniques. These patterns are then accented with rose gold plating, creating a complex interplay of texture, depth, and metallic brilliance — a visual complement to the earphone’s stellar acoustics.
Musicality-Driven Cable Design
To complement the IEM’s rich tuning, Jomo Audio includes a custom 4-core cable made from monocrystalline copper infused with gold-silver alloy. This blend maintains the natural warmth of copper while enhancing resolution and treble clarity. The result is a cable that supports dynamic expression and musical nuance. A rhodium-plated 4.4mm balanced plug ensures excellent conductivity and durability for high-performance portable sources.
Immersive Sound Like a Starfield in Motion
Nautic Stellar delivers a grand, spacious presentation with excellent lateral spread and imaging precision. Its frequency response is balanced and musical, offering a natural warmth that avoids harshness or fatigue. Treble extension is smooth and airy, while the midrange remains intimate and detailed. The bass is elastic and well-defined, with excellent control that highlights the physicality of instruments like upright bass or jazz drums. This is not just an IEM — it’s a window into a musical universe, where every detail shines like a star in the night sky.
