On receiving multiple requests from friends for their own headphones, what started as a passion project in a garage became a fully-fledged business. Based in Solvenia, all headphones are hand-built. The company launched with the S4X model in 2019, followed by the S5X and launched the X1 in 2025. OLLO Audio’s vision is that headphones should be durable, fully repairable with home tools and made to last, which is why every OLLO model is designed with replaceable parts, making them some of the most sustainable and long-lasting headphones on the market. Their designs avoid plastic where possible, instead using metal and wood to create a design that’s both visually striking and built for longevity.
