Gray Ghost Amphibian II Headphones: incorporates a number of dramatic improvements in weatherproof/submersible headphone design. The design is 100% waterproof and totally submersible to a minimum of 30 feet! No compromise in sound quality for functionality.

IP68 rated connector: The Minelab Equinox Series connector has the same IP68 rating. Our quality, fully waterproof connectors protect the integrity and functionality of your detector.

  • Radical redesign of the traditional method of waterproofing wired connections on Piezo transducers: All underwater headphones use a Piezo type “buzzer” speaker system because land use paper speakers would disintegrate after getting submerged. However, the tonality of the piezo system is unfortunately compromised due to the piezo being dampened with silicone to waterproof the connections… Actually degrading the “buzzing” action of the Piezo. We developed a waterproof “sound box” for the Piezo and the connections are internal. The Piezo will then deliver its full range of audio rivaling land-use paper speakers.
  • Quality, comfort, fit and finish you expect from Gray Ghost: Once worn, you won’t believe our headphones are designed for underwater use. They are as plush or plusher than most land phones. They fit snug and have soft cushions that won’t slip off when encountering waves, submersing your head or diving for treasure. Detect for hours in total comfort.
  • Attention to detail: We read the user forums to learn everything we could to improve and surpass the Minelab headphones. Our improvements make the detecting experience much better. Improvements like lengthening the coiled wire cord and leaving enough straight wire coming off the connector to allow clipping to the hook under Minelab’s arm cuff. This feature keeps the cable out of your way, eliminates a stress point at the rear of the detector, and helps keep the cable tangle free.
  • Longer Cable Wire: Our coiled wire is longer, stronger, and more durable than most standard headphone wiring. We make our waterproof headphones to last!
