Headphones had been around for decades, but no one produced high fidelity headphones for the sheer enjoyment of music. Until 1958, that is, when John C Koss showed the Koss SP/3 Stereophone at a trade show. That introduced personal, private listening to the world.
In the more than six decades since, Koss has continued to craft a range of headphones, from the lightweight portable models in the Koss Porta Pro range up to over ear closed back models and to high-end electrostatic models.
But apparently the company has fun, too. It still has the original Koss SP/3 Stereophone listed on its product page, albeit showing it as “Sold out”.
