Brand: used Was made to sennheiser hh650, was operated for 1.5 months, then the headphones were sold. cable is sold separately. Length ~162cm The cable is massive, but soft. Double layer insulation: black and clear. Conductor: copper (not litz) 160 * ~ 0.06-0.07mm Sound (in my ear): better detail at mid frequencies. Delicate and more analog sound at higher frequencies. Jack is straight Amphenol. There is a small problem: two left connectors have been sent to me, it does not hinder me in any way, but I can mark somehow the right channel, if necessary.
