Chosen Solution

The wire is exposed & ripped a bit. Can it be fixed or the wire be replaced or something like back in day were I can just put wires back together n electric tape!!! But I know not the case with this huh?

Sadly these are molded so you can’t get to the needed connections to replace the cable. Time for a new headset. Don’t scold your dog too harshly, he loved the taste of your sweat (salty)

Darryl Sabourin  post some images of where the wires are chewed. If it is far enough away from the earpieces it might be possible to repair those. Remove the insulation and you should see the bare wires. The issue here will be that those wires are really fine and will require some steady hands. Adding images to an existing question
