SIVGA Unveils the SV021 Pro: The Next Evolution of the SV021 Closed-Back Headphone

Brighton, UK – Embargoed until 5th February 2026: SIVGA announces the SV021 Pro, the successor to its popular SV021 closed-back dynamic headphone. Building on the foundations that made the original SV021 a favourite 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.

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

The original SV021 earned its reputation by getting the fundamentals right — a well-judged balance of musicality, accuracy, and all-day comfort. It became a long-standing favourite 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.

At the heart of the SV021 Pro is SIVGA’s newly developed 50mm aluminium diaphragm dynamic driver. Utilising a five-layer composite diaphragm engineered to achieve an ideal balance of rigidity and damping, this design delivers enhanced mid-to-high frequency clarity, precise detail retrieval and a controlled, natural presentation across the frequency range.

Further improving driving efficiency with the ultra-fine black copper aluminium alloy voice coil, the SV021 Pro also features a dome-shaped six-layer reinforced composite structure paired with a specially engineered high-performance magnetic circuit conversion system that enables highly efficient, low-distortion energy-to-sound conversion.

Continuing with 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 whilst maintaining clarity.

Designed for extended listening sessions, the SV021 Pro incorporates widened adaptive comfort ear pads made from skin-friendly velour that are soft, breathable and gentle on the skin.

Supporting this is a precision-machined ergonomic support structure, crafted from high-quality metal and finished with a refined, uniform surface and distinctive tactile quality. Its curved, adjustable design provides stable support and balanced pressure distribution, reducing fatigue while maintaining a secure fit.

The SV021 Pro is supplied with an OFC detachable cable, using oxygen-free copper to ensure 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 a natural and detailed sound.

By combining advanced driver technology, carefully selected materials and a comfort-focused design, the SIVGA SV021 Pro delivers a closed-back listening experience that balances technical performance with timeless craftsmanship.
