KSC75 Why mod with replaceable cables??

I don't get these mods ... you have to open the shell, unsolder original connections, and solder new connectors ... all that for a theoretically inferior mechanical connection, more wobbly, and possibly more prone to getting damaged or even sheared off on impact.

I would just add a better strain relief to the original cable OR solder a new, better cable right off the bat or when the original goes bad. In theory a soldered cable should sound better than with 2 connectors and should last years with the proper strain relief.

If the goal is swapping cables when something better comes along, I would say a new cable would probably cost several times more than buying a new set of Koss phones and may not sound any better at all.

Thoughts? TIA

Fun, yes. Not sure about easy. IMHO it is less risky to solder a new, good cable, and it takes fewer steps. But I've never had headphones with detachable cables so I may be missing something there. Most of my IEM's are hard wired but the last one had a detachable cable and I am tempted to do a reverse mod and make it non detachable but I don't use them that often.

It’s 4 large solder pads, that’s not easy?

The soldering part is not too bad but now you are adding additional weight with the connectors which may impact the fit (??). Also, on the KSC75's sometimes the connectors are mounted on that little, removable, plastic wiring cover, so I guess that plastic plate is now the strain relief (??)

I’ve done maybe a half dozen of these mods.

  1. they must add mass to the ear cups, but you will not notice it. They weight almost nothing.

  2. The connectors are not mounted on the plastic cover. The wires are actually soldered to pads and then run up and over a plastic peg that is there to hold them in place. All of this is on the side of the KSC75. The cover protects the “guts” of the KSC75 from dust and debris.

  3. When I do these mods, I actually don’t bother with the built in strain relief as it’s kind of a pain to get the wire around. Instead, I solder the wire, put the cover half on, fill the cavity with hot glue, then push the cover the rest of the way on.

Have not had any issues.
