SIVGA Robin SV021 - Black

The Robin SV021 pairs natural high-density rosewood earcups with precision five-axis CNC carving, multi-stage grinding, polishing, painting and piano-gloss finishing. A high-protein leather headband with computerized 3D embroidery and durable metal fittings adds a luxurious touch, while detachable ultra-soft memory-foam earpads wrapped in fine leather ensure a comfortable, skin-friendly seal and easy replacement over time.
At its core sits a custom Φ50 mm dynamic driver featuring a polycarbonate-and-fiber diaphragm developed in-house for exceptional elasticity, detail and natural tonality. A 3 mm-thick Nd-Fe-B magnet provides powerful magnetic flux, while a copper-clad aluminium voice coil delivers high sensitivity, transparency and dynamic performance with minimal distortion.
Designed for everyday and audiophile use, the Robin SV021’s 32 Ω impedance makes it effortless to drive from smartphones, computers and professional audio players. The closed-back design delivers balanced three-way tonality, wide soundstage and clean separation. A changeable cable system accommodates 3.5 mm or 4.4 mm plugs, letting you upgrade or swap cables tool-free to match any listening setup.

Sculpted Rosewood Ear Cups
Each earcup is precision-machined from high-density rosewood using five-axis CNC carving, then polished through multi-stage grinding, painting, and piano-gloss finishing. This process harnesses the wood’s natural damping properties to lock out unwanted resonance and impart midrange warmth, with each pair displaying a unique grain pattern.

Premium Leather Headband
Wrapped in high-protein leather and stitched with computerised 3D embroidery, the headband delivers uniform tension and lasting durability. Smooth metal sliders enable tool-free sizing adjustments, ensuring balanced weight distribution and a luxurious feel during extended listening.

Replaceable Memory-Foam Earpads
Ultra-soft memory-foam pads conform to your ear’s anatomy for a secure, pressure-relieving seal that minimizes fatigue. The earpads detach effortlessly for hygienic replacement or material swaps, preserving acoustic integrity over years of use.

In-House Polycarbonate–Fiber Diaphragm
At the core of the 50 mm driver lies a custom diaphragm crafted from polycarbonate and fiber. Its ultra-thin, lightweight profile accelerates transient response and delivers razor-sharp detail, faithfully reproducing complex musical textures across the soundstage.

High-Performance Magnet & Voice Coil
The 3mm magnet of teh driver generates a powerful, uniform field, while the copper-clad aluminium voice coil balances low mass with excellent conductivity. This synergy boosts sensitivity, expands dynamic range, and controls distortion even at higher volumes.

Tool-Free Interchangeable Cable System
The detachable cable pairs silver-plated, oxygen-free copper conductors in a flexible Litz weave with satin-finish PVC insulation for tangle resistance. Quick-release 3.5 mm and 4.4 mm connectors click on without tools, letting you upgrade or swap cables seamlessly.
