Headphone, Two Ear

This headphone has two earphones with a soft, plastic-covered rubber ear cushion. The headphone uses an N-type (1.5 volt) battery which is located in the battery box along the cable. The volume control allows the hydrographer to increase the volume when encountering loud background noise during a measurement and an On/Off switch to save battery life. Includes 1/4" Socket Phone Plug.

As of summer 2022 the internal wiring on the headphones was improved to make it more robust.
