Thanks for doing an awesome job on my headphones...even added on/off switch!! Thanks Steve,that was mighty cool of you!!!! Ray

You are more than welcome Ray, the switch is actually a compatibility switch or some call it a mono/stereo switch. It makes the phones able to work on different brands/models. I would be happy to fix (if I can) anyones headphones if they would like me to. Thanks for the kind words Ray. Steve.
