SIVGA Que - Dynamic Beryllium Drivers In Ear Isolating IEM Earphones

White Maple Wood Chamber
The rear housing of Que is crafted from North American white maple, carefully polished, stained and air-dried to lock out unwanted resonance. This natural material brings warm harmonic richness to midrange frequencies and adds a unique aesthetic to each pair. It also promotes durability and dimensional stability over time.

Precision Die-Cast Zinc Alloy Nozzles & Vents
Zinc alloy components are formed by high-precision die-casting to ensure uniform guide-hole and vent dimensions. This level of control optimises diaphragm movement, improving transient response and extending driver lifespan. The robust alloy further reduces chamber resonance for a purer listening experience.

Beryllium Diaphragm Dynamic Driver
At its core, Que uses a 10 mm dynamic driver with a beryllium diaphragm known for its extreme rigidity and low mass. Beryllium effectively resists standing waves and vibrational distortion, delivering crisp treble and tight, realistic bass. Its lightness also contributes to faster driver response for enhanced clarity.

Dual-Cavity Acoustic Architecture
The driver’s single-magnet dual-cavity design and diamond-cut skeleton channels guide sound waves with precision. This architecture expands the soundstage, improves detail retrieval and maintains balanced tonal performance across frequencies. A copper-ring stabilisation system within the chamber further minimises distortion for lifelike audio reproduction.

Ergonomic 3D-Moulded Design
Que earphones are shaped using 3D ear-scan data to fit the contours of the ear perfectly, ensuring secure, fatigue-free wear during long sessions. Replaceable silicone tips and flexible around-ear cable routing reduce microphonics and maintain stability in any activity. This thoughtful engineering puts comfort at the forefront without sacrificing acoustic seal.

Silver-Plated Oxygen-Free Copper Cable
The included detachable cable features standard 0.78 mm 2-pin connectors and high-purity oxygen-free copper with silver plating and Litz braiding. This construction enhances conductivity, channel separation and noise rejection for crystal-clear vocals and instruments. Its braided design resists tangles and allows quick swaps for customised setups.
