Connect Quick Disconnect to headset with a simple push until they snap together
Find the compat switches on the headset side of the cord connections. Use a ball point pen to change the 1-2 and 3-4, and set them for your device. (List found at the 1:42 mark in the video. 2 & 3 is the most common setting, but you can freely experiment if you need!)
Connect your Quick Disconnect to your phone (or computer, if USB) and get ready to take some calls – You’re done!
