SUPRA

SUPRA is a Swedish audio brand with roots in Jenving Technology, long recognized in the Hi-Fi world for its cables — trusted by demanding clients such as the Swedish and American air forces and Koenigsegg Automotive. Drawing on that engineering heritage, the idea to extend SUPRA into headphones emerged in 2010, driven by dissatisfaction with the headphones available on the market at the time. The result was NiTRO, SUPRA's first headphone model, launched in 2014 under the Sound by Sweden brand and honored with multiple industry awards, including "Product of the Year" in the in-ear category and "Best Buy" among premium headphones.

Today, SUPRA headphones are developed by a team of engineers and innovators rooted in the brand's cable-making tradition, combining that technical foundation with new materials and technology under a concept the brand calls "New Generation of Sound." True to its "Made with Military DNA" heritage, SUPRA develops and produces its headphones entirely in-house, allowing full quality control at every stage and ensuring the final product meets the exacting standards the brand is known for.
