This FREEDOM upgrade cable is designed for the Sennheiser HD580, HD600, and HD650 headphones.
The FREEDOM headphone upgrade cable is made with high purity (99.99997%) UP-OCC (Ultra-Pure Ohno Continuous Cast) Copper conductors. Thanks to FREEDOM's low noise floor, thoughtful design, and high performance termination, you can extend the performance of your Sennheiser headphones simply by replacing the original cable.
UP-OCC Copper is known for its low noise floor and nimble dynamics. Each conductor is made up of strands that have been pulled from a single Copper crystal. This lack of crystal boundaries has many electrical and sonic benefits.
Freedom uses a pair of UP-OCC coaxial conductors. Each leg of the cable is shielded all the way up to the headphones to keep noise out. The dielectric is a super low-loss, nitrogen injected, foamed polypropylene that damps out noise, but passes audio signals without compromise.
Due to its large diameter (8mm) and slightly limited flexibility FREEDOM is recommend for integration with desktop and home audio systems. If you want something for portable use please take a look at our REALITY and VITALITY headphone upgrade cables.
