Gray Ghost and Sunray both make headphones specifically for the CTX. In order for the detector speaker to shut off when the headphones are plugged into the CTX the wiring of the headphones has to be done in a different pattern than most headphones. I believe most headphones work okay when plugged into the WM10, however. An adapter pigtail can be made to allow most headphones to work properly as well. I like the Sunray phones, as there is a volume adjustment on each ear and the tones are crisp like I prefer. People’s hearing is different, so that is for the individual’s preference.
