The DUMMER cable is the "unmagical" stock cable for Dan Clark Audio's headphones. You can get a replacement in 3.5mm with a screw on 6.5mm adapter, or upgrade to the balanced 4.4mm or XLR version.
Sturdy balanced cable with 4 pin connectors on both ends. The cable itself has a woven sheath wrapping everything that’s a bit stiff, hence the 4 stars. Otherwise, it’s very solid. The connectors on the headphones themselves are directional and take a bit of trial and error to find the right position, but once they’re in, they stay connected until you disconnect with the quick release.
