Sennheiser HD 800 aftermarket cable

Meestickbuf, search "synergistic foundation" and sort by date, not relevance. Numerous mentions of Foundation series cables, although likely not in the headphone space. I developed these cables for my Sennheisers, because I love them and you likely will too after 30 days but if not, no big deal.

Atmosphere headphone cables were engineered prior to Foundation and is based on our Tricon geometry. As for the Foundation headphone cables, it’s a pure 6-9’s silver conductor in an air dielectric, 100% handmade geometry and terminated by hand in my Southern California factory and conditioned on our massive Tesla Coil. It has the same house sound as the rest of the Foundation Series, but in the case of the Sennheiser variant, is specifically voiced by me on Sennheiser headphones. Both are great but I’d likely go for the Foundation at this point.
