headphone repair question-

[se stan]

a buddy of mine has a dfx and when new headphones are pluged in they do not work but the original whites seem to work and he says they crackle sometimes.
tried 2 different headphones on his unit and on mine..my unit has no problem ... his is silent..
i guesing the jack on the detctor has to be removed and replaced..
what is that jack exactly called and im thinking radio shack unless you guys can give me a link where i can get one..

thanks .....stan

It's either going to be a stereo or mono jack. Look at the plug that is meant for the detector headphone socket. If it has only two contacts on the shaft that are seperate then it's mono. If it has three seperator shaft areas it's stereo. Are you sure his machine doesn't require one type of headphone or at least the right plug (mono or stereo), while yours uses the other type? Some detectors are mono and some use a stereo plug. If you are plugging the headphones in with the wrong plug they might do what you are talking about.

Almost all detectors are mono, the only true stereo one i can think of is the nautilus, the difference in say the DFX and a minelab is that on a stereo jack the detector will either contact the centre(bit between the 2 black insulators) or the long part closest to the cable, the front point is usually the common. Almost All detector specific headphones have some means to change from one to the other to make them compatible with all detectors, be it switch or reversing the cable, have a good look at the phones for this switch as in some its inside the earcup(predator ml's) others have a detatchable lead that has a stereo jack on one end and a mono on the other, all it does by reversing it is it uses a different wire(either centre or the long)to send the signal

Yea, I'd figure most if not all detectors are mono, but I'm pretty sure I've heard that some want one plug while others want another (mono or stereo). Could be wrong, though.
