SIVGA, a company renowned for blending traditional craftsmanship with modern acoustic engineering since 2016, has announced the launch of the SV021 Pro, the successor to its popular SV021 closed-back dynamic headphone. Building on the foundations that made the original SV021 a favorite among audio lovers, the SV021 Pro refines every aspect of the design to deliver an even more detailed and natural listening experience through carefully selected materials and precision-tuned components.

The SV021 Pro marks a significant step forward for the brand’s entry-level premium line, moving beyond standard dynamic drivers to a more complex, multi-layered composite system designed to restore the emotional character of high-resolution audio.

Available from 5th February 2026 from Amazon and selected retailers worldwide, the SV021 Pro is priced at £179 / $179 / €199.

The Heritage:

The original SV021 earned its reputation by getting the fundamentals right, which is a well-judged balance of musicality, accuracy, and all-day comfort. It became a long-standing favorite among home listeners and hi-fi enthusiasts for good reason. The SV021 Pro builds directly on that foundation, refining the tuning for improved detail and dynamics while preserving the easy-going, genre-agnostic sound signature that defined the original.

New 50mm Aluminium Dynamic Driver

At the heart of the SV021 Pro is SIVGA’s newly developed 50mm aluminium diaphragm dynamic driver. This system utilizes a proprietary material composition to achieve a high-fidelity presentation:

1. Five-Layer Composite Diaphragm: Engineered to achieve an ideal balance of rigidity and damping, this design delivers enhanced mid-to-high frequency clarity and precise detail retrieval.

2. Ultra-Fine Voice Coil: Utilizing a black copper-aluminium alloy voice coil, the system improves driving efficiency, allowing the headphone to perform optimally even with lower-powered mobile sources.

3. High-Performance Magnetic Circuit: A specially engineered conversion system enables highly efficient, low-distortion energy-to-sound conversion, maintaining a natural presentation across the frequency range.

4. Reinforced Structure: The dome-shaped six-layer reinforced structure ensures structural integrity during high-excursion movements, minimizing unwanted resonances.

Natural Materials, Crafted for Comfort

Continuing SIVGA’s commitment to material-led design, the SV021 Pro features handcrafted natural wooden earcups available in two distinct finishes: Beechwood and Zebrawood. Each wood option not only provides a unique visual identity but also contributes subtly to the headphone’s natural tonal qualities, enhancing warmth and musicality.

Designed for extended listening sessions, the SV021 Pro incorporates:

• Widened Adaptive Comfort Ear Pads: Made from skin-friendly velour that is soft, breathable, and gentle on the skin.

• Ergonomic Support Structure: Precision-machined from high-quality metal, the curved, adjustable design provides stable support and balanced pressure distribution, reducing fatigue while maintaining a secure fit.

Oxygen-Free Copper Detachable Cable

The SV021 Pro is supplied with an OFC (Oxygen-Free Copper) detachable cable, ensuring low-resistance signal transfer with minimal distortion. The cable is soft, corrosion-resistant, and durable, offering both long-term reliability and easy maintenance while preserving the natural and detailed sound intended by the engineers.
