These headphones has been tested and works perfect.
Most of these detectors are Amazon returns.
Ie: They got it as a gift and didn't want it. Buyer remorse. Had a change of thought and decided to take up basket weaving. Who knows?
This means most of them have never even seen dirt. Their boxes are banged up but the detector is brand new.
Headphone jack size: 1/4"
