Perfect or near perfect condition Sony MDR-Z7 headphones with internal Mogami wire upgrade, cable jack upgrade to three pin mini XLR (Audeze) and Nucleotide balanced cable. The cable terminates with two 1/8" jacks for direct connection to Sony PHA-3 or Pono player. Also included is an adapter to terminate in 4 pin balanced. Ridiculously comfortable phone with some of the best bass I have heard. These can be worn for hours and hours with zero fatique. Original box.
