3CLEADER Replacement Cable Upgrade Cord for Sennheiser HD650 HD600 HD580 HD565 HD545 HD525 Headphones

Connector is too wide, blocked by the headphone shell. Was able to cut part of the connector away with razor blade. Easy fix. Now works well. Good flexible wires.. (Pins fit ok. Cut was made on the black connector plastic, which has lines where one might cut.)

Very nice and flexible cable!Sounds and performing great only one thing- the two pins connector to the headphones are very tight and hard to be disconnected

The connectors are just a bit too big, they are ok to plug in to the headphones, the cable got stuck in my desk when I stood up, as the connectors are too big they didn't unplug from the headphones, instead the cable broke. The next problem was to get connectors our of the headphones, had to use a pliers to remove the connectors and almost broke my headphones. Do not buy this cable.

This cable will be mainly used for the HD 6xxThe only difference between this cable and stock is “aesthetic..” The red black has a good contrast than the regular stock cable and this one is shorter.No changed in audio quality, audio quality remains the same. I’ll say it again this cable doesn’t improve audio quality.So the orientation of the pin goes one way, from the photo the L or R Marks are inwards instead of outwards and the polarity is correct which what only matters (on stock L/R marks are outwards, still only goes one way).If you ever tried having the markings outward, try not to force it if it doesn’t insert, try it other way it should just go in smoothly.Another thing to keep in mind is that it’s a bit tight when taking it out compare to stock.
