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. Made in Australia. Can also be connected to a WM 08 Wireless Audio Module.
