The key features of the VSA-PM fully planar aluminum ribbon headphones (low distortion, fast transients, no crossover vibration, and phase coherence across the entire frequency range) make the sound of these planar ribbon headphones exceptionally natural, transparent, and expansive, with the "pure high-fidelity" qualities of high-quality electrostatic headphones. The soundstage is typically remarkably expansive and precise, with clear and stable imaging, demonstrating true high-end quality.
