Zynsonix Audio, LLC is a boutique audio brand specializing in aftermarket headphone cables that stands for top quality materials, experienced craftsmanship, and most importantly: great sound. All Zynsonix audio cables are proudly hand assembled just-outside of Baltimore, Maryland with the same two hands that have been building audio electronics for over 15 years. That's right, you can rest assured that every cable created will be consistently well-crafted, after all, they bear the Zynsonix brand. These cables are built as carefully as I would build them for our own system, and because of that, I do not rush through orders to make a few extra bucks. Order with confidence, as Zynsonix cables feature audio-grade materials, from custom-spec wire and carefully vetted connectors to Cardas silver and copper content solder.
