These headphone cables are 2 meters and come with a 4 pin XLR to 1/4" adapter. They've only been lightly used as a store demo.
The Heimdall 2 Headphone Cable consists of 32 AWG 7/40 conductors which have been individually insulated and twisted using Litz construction. Litz construction increases the pliability, as well as eliminates triboelectric noise within the cable and improves upon mechanical damping. In order to accommodate the added durability demanded from headphone cables, Nordost has included an Aramid fiber strength member to the construction of this cable. Integrating Aramid fibers into the cable design not only ensures its mechanical integrity, transferring the strain away from the cable’s conductors and to the fibers themselves, but the resonating properties of Aramid fibers also enhance sound quality.
