My dog chewed the wire & now its frayed with exposed wires with no!
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?

ANSWERS:

"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)"
