The 1/4" headphone jack on my Omega is so tight that when I plug the headphones in or unplug them, I have to hang on to the control box to even accomplish this.---It's that tight with ALL my different 1/4" headphones (I mean as in ridicuously tight).---I've never had this problem with any of my many detectors before.----I love this little machine & it works absolutely perfect when the headphones are plugged in--but it's just this TIGHT headphone jack thing.----Other than sending it in--is there anything that can be done about this?----------Thanks, Del
