The world’s first open headphones
But it was in 1968 that a somewhat ‘accidental’ invention led to a product that was to outdo even the highly successful microphones. Sennheiser developed the legendary HD 414, the world’s first open headphones – a product that created the headphone market all by itself. The Sennheiser headphones were so successful that, just ten years later, they already accounted for more than 50 percent of the company’s total sales.
