Hello all! Recently, I've come across some issues with the Koss KSC-75 drivers. The problem itself isn't the driver as a whole, but the coil connections to the contacts (which lead to the cable and the plug). Twice as of now, I suddenly lost feedback from one of the earphones. Thinking it was...

Yup, tried that today and the diaphragm was there, glued. I might try to fix the contacts in the front, but I'm afraid I might end up breaking the voice coil wires (are they really that thin? :() Thanks for the help, tho. :) If you have any experience fixing the voice coil leads in the front...

Hello guys! The day before yesterday, I started noticing some cracks on my right KSC-75 driver, and it sounded like it was due to a loose cable. I thought it was time for their first recable! However, before I tried to recable them, I tested continuity bewteen leads and the plug and it was...

Hello guys! Recently I posted about a problem I had with my PortaPros, and after some troubleshooting I realized it was the drivers' (actually, their connection from the coil to the soldering pads) and lost hope on bringing them back to life. As such, I wanted to go again with Koss, since my...

Unfortunately, I think it may have to do with the drivers. When I measure them, I get the same response as if I were measuring nothing. I think it might have to do with the coil wires being broken (as I recently noticed the slimmy and sticky substance that runs from the bottom is cut out), and...

  Thanks for the response! I just tested what you asked: They all measure 0 ohms, no continuity. I'll resolder them meanwhile. BTW, the cable I'm resoldering them into isn't the stock one. Over the days, the original cable was destroyed (mostly by skin oil hardening) so I'm using a different...

Hello all! I'm running across a problem unfamiliar to me until now. I've had the PortaPro's since 2010, and have had no problem so far. I've changed the plug and rewired them multiple times with success, and had no isues until today. This morning, one of the drivers stopped working. After...
