Brand new in the box "Treasure Wise by Calrad" metal detecting headphones. This is the headphone I have detected with for years. I used them with Whites, Garretts, Tesoro and Bounty Hunter. I think they would work well with Fisher, Minelab, and Troy too!!! Headphones extend battery life and help you hear fainter deeper targets. How? They block out background noise. These have a straight jack, coiled cord, adjustable individual volume controls, a stero/mono switch and an adjustable headband.
