Nordost Heimdall 2 is in great condition, fully working. Comes with original box and 2 adaptors (both are terminated with a 4pin balanced XLR female connector on one end and either a 3.5mm stereo mini or a 1/4 inch (6.3mm) stereo jack on the opposite end).
No invoice, as I'm not the first owner of this cable. Cable fits Audeze headphones, ZMF headphones, Meze Empyrean and many other headphones with 4pin mini XLR plugs.

I'm selling this phenomenal hp cable with extra adapter 2HEHP2XLRF (2x 3 Pin XLR Female to a 4 Pin XLR Female adapter). This adapter fits Chord Hugo TT 2 speaker XLR outputs, so you can feed very power demanding headphones with this cable set and take advantage of Chord's full potential (up to 18W RMS@8Ω).

Price of this set as new more than 900€!!
