NiTRO – Handmade

In accordance with our No Nonsense philosophy, NiTRO is made only from the best commercially available materials. Kevlar is used for cable strain relief, carbon fiber for endurance and titanium for die-hard, light weight, ear capsules. These materials, combined with advanced technology, are part of the reason why we can deliver world-class earphones, both in terms of sound, performance and quality. Put these superior materials together by hand, supervised by multiple quality steps and you will achieve unsurpassed performance – There is no mystery behind SUPRA being an approved supplier to both Swedish and American Air Force!

Kevlar reinforced SUPRA cable

The so often overlooked interconnect between the earphone’s individual components is paid special attention to on each model from Sound by Sweden. The over 40 years’ cable experience from our joint co-operation, lay the very foundation for a transparent, strong and durable interconnect with exceptionally low signal degradation.

Our design is a flat, tangle-free cable, offering 7N purity copper conductors, Kevlar reinforcement for maximal strain relief, yet highly flexible cable, for best sound and long life.
