Vintage Koss K/6ALC Stereo Headphones – Tested Working

Vintage Koss K/6ALC over-ear stereo headphones from the late 1970s. Tested: both left/right channels work and both individual volume controls function normally. When the controls are moved very rapidly/aggressively, there can occasionally be a brief crackle. Foam-filled vinyl ear cushions are still soft and intact with no visible tears. Includes pictured extension cable/connector. Connection is secure during normal use; pulling it hard enough to partially disconnect can cause temporary contact noise. Good overall vintage condition with normal age-related cosmetic wear. $50 CAD.
