Cobalt Cable is a Washington state based company, founded by John Coleman, that designs and manufacturers high-end audio and video cables and interconnects. Coleman Cable's belief is that high quality cables shouldn't have to cost a fortune. Each cable is hand assembled and tested in their factory and come with a 90-day money-back guarantee and lifetime replacement warranty.
Notable Cobalt Cables include:
