D-465

Sony advanced its skip-protection approach with the D-465 by replacing the short, compressed buffers of earlier Discman models with a twenty-second reserve that stored audio in its original form. The player read ahead at high speed, filling a longer buffer that kept playback steady even after extended movement, giving it a noticeably smoother response than units built around smaller memory systems.

The housing reinforced this mobile focus. The lid used an aluminum panel, and a sliding hold shutter covered the control cluster to prevent accidental input.

Both the main unit and the inline remote carried EL-backlit LCDs for low-light use. A 3.5 mm optical output provided a direct digital path to recorders or DACs without relying on larger home-audio connectors.

Long playback times made it practical for daily use. Weight remained manageable at roughly 225 grams with batteries installed.
