Episode Overview In this episode of The Design Vault, hosts Albert Shum and Thamer Abanami explore the remarkable story of the Koss Porta Pro, a pair of headphones that defied every rule of consumer electronics and emerged as an unlikely icon. Launched in 1984 at $49.95, these skeletal-looking headphones still sell for the exact same price today, effectively making them much cheaper due to inflation. From John Koss's accidental entry into electronics to a bankruptcy-driven product that became permanent, the Porta Pro story shows how understanding human needs—not industry assumptions—creates timeless design. This episode uncovers why a product initially rejected by some for looking "too cheap" became a cult object spanning from veteran audiophiles to Gen Z walkman enthusiasts, and how its "evergreen product strategy" challenges everything we believe about planned obsolescence.
