Advanced 12-Driver Quadbrid System

STELLA integrates four distinct driver technologies into a single coherent acoustic system:

Low Frequencies
9mm dynamic driver paired with dual balanced armatures in a two-stage chamber for deep, controlled bass with excellent texture and authority

Midrange
Three balanced armature drivers tuned for accurate vocal presence, tonal realism, and natural timbre

High Frequencies
Dual planar magnetic drivers combined with four electrostatic tweeters to deliver exceptional speed, micro-detail, and extended treble response up to approximately 45kHz

This complex arrangement is governed by a proprietary 6-way crossover network and multiple precision-tuned sound tubes, ensuring seamless integration between drivers and consistent frequency response.

Reference-Grade Tuning

STELLA is tuned for accuracy rather than artificial coloration. The sound signature prioritises:

Exceptional clarity and transparency
Wide, holographic soundstage
Precise instrument separation
Natural midrange tonality
Deep yet controlled low-end extension
Airy, extended treble without harshness

The result is a balanced and resolving presentation suitable for studio reference monitoring and high-resolution music playback.

Premium Build & Materials

STELLA’s housing is machined from 6061-T6 aerospace-grade aluminium, selected for its strength-to-weight ratio and acoustic stability. The 316 stainless steel faceplate enhances structural rigidity while contributing to its distinctive flagship design.

A 9H hardness sapphire glass accent adds durability and visual refinement, reinforcing STELLA’s position as a luxury, high-performance in-ear monitor.

High-End Cable & Connectivity

Included is a premium hybrid Litz cable constructed from a blend of copper, silver, and gold-plated conductors to optimise conductivity and minimise signal loss. The cable terminates in a 4.4mm balanced connector, ensuring maximum performance when paired with balanced outputs on high-end digital audio players and DACs.

The detachable cable design allows future upgrades or replacements.
