Up for sale is a used set of AKG K553 Pro headphones that will come with Brainwavz HM5 pads (as well as the originals) as well as an Anker 3.5mm to 3.5mm cable. The headphones have been modified for a detachable 3.5mm cable. Sound quality is just the same as with the attached cable.
There are a few nicks and scratches on the outside of the cups and on the headband but they do not affect the sound at all. You could maybe touch them up with a sharpie and never notice them.
I purchased these headphones new on MassDrop a couple years ago but I just don't use them enough and would like to get something more portable (Bluetooth).
