Honed in Gothenburg, Sweden, Jorma is the result of decades of audio problem-solving and craftsmanship. What began as an innovative solution to an insulation issue has evolved into a brand celebrated for its peerless sound clarity. Each Jorma cable is handcrafted by master technician and head of production Bernt Jansson, using traditional techniques that guarantee consistency and quality in every interconnect and power cable made. The focus has always been on preserving the integrity of the original audio signal—delivering natural, transparent sound without distortion.

Founded by Jorma Koski in 2001, the company grew through strong relationships and collaborations, notably with Marten, a partnership that helped position Jorma cables among the best in high-end audio. After Marten took over in 2016, they remained dedicated to Koski’s vision of precision and excellence. The use of 99.999999% pure copper highlights Jorma’s commitment to using only the finest materials—not for cost, but for performance. With a legacy built on problem-solving, craftsmanship, and consistent quality, Jorma continues to push the boundaries of audio fidelity.
