Sivga SV021 Robin SV021
The handcrafted natural rosewood closed-back design houses 50mm dynamic drivers with a proprietary polycarbonate film diaphragm, delivering detailed transients at a 32-ohm impedance and 105dB sensitivity. Weighing just 275g, sculpted protein leather pads and an adjustable headband provide lasting comfort, while the low power requirements make it easily driven by phones or laptops. Best for casual listeners and style-focused buyers who prioritize wooden aesthetics and wired simplicity, though its weak 22.3 calls score makes it unsuitable for frequent voice use.
