SUPERCLEAR EARPHONES UNDER CHIN. In warm weather your ears can get very hot with the big headphones. they act like black solar panels which fry your head! And you cant wear the required broad rimmed hat with them. That's why Jack has manufactured these under chin earphones. They are very cool to wear They give fantastic clarity and sound for their size, being comparable to the $150 Telex models and far better than $75 Lanier model. They enable you to hear surrounding bush/vehicle/voice noises too, which the big over- ear models dampen. They are now with improved with longer 1.5 metre cable, hard wired big plug (no adapter needed for Minelabs) and a better plastic band. (old model is till pictured)
