Detector Pro Black Widow Headphones. Black Widow headphones were designed to accommodate the professional detectorist with special hearing requirements and for environments with high ambient noise levels. Large extended muffs are designed to block ambient noise to a higher degree for huntsites in proximity to urban traffic and surf roar. The Black Widow headphones contains a dual mini-toggle switching system like our famous Gray Ghost Ultimate. One switch provides greater compatibility with detector audio systems and the other switch allows signal limitation when extreme volume is not required. Also provided are two independent volume controls for those detectorists with unequal hearing ability in each ear. You still get our "industry first" quality components, design and construction without compromise. Black Widows are "deadly", but guaranteed not to "Sting" you!

CAUTION: The significant volume output of the Black Widow compared to our main line of headphones requires us to warn the consumer of potential eardrum damage if detector signal is not regulated to tolerant levels. Without the limiting circuit engaged, we recommend starting with a minimal headphone volume control setting with detector volume at maximum, then gradually increase headphone volume controls as needed and tolerated.
