Genuine Professional Minelab Underwater Headphones. Not a "copy", not a "Look Alike" but the REAL THING! These phones are perfectly matched electronically with your CTX 3030 metal detector, not only waterproof, but submersible to 10 feet. Phones have completely sealed speakers for each ear, comfortable ear pads (flexible) to create a perfect fit with adjustable non-breakable headband to fit each individual. Attention to detail even includes drain holes in each ear cup to balance pressure, no metal parts to corrode from salt water use, plus a very heavy-duty coiled cord with sealed waterproof connector.
