Eartec ProLine Dual-Ear Headset for Other Brands
This is the dual-ear ProLine, for positions where ambient noise wins against a single cup. Like the single-ear model it carries its own amplifier and volume control in the ear cup, so no belt pack and no inline amplifier sit between the operator and the intercom. The boom rotates and mutes the microphone when parked upright.
Seven connector versions cover most wired party lines and radios: 4-pin and 5-pin XLR male and female, Kenwood and Motorola two-pin molded plugs with inline push-to-talk, and a 3.5 mm TRRS plug. XLR versions use a dynamic microphone element and the molded-plug and TRRS versions an electret element, which is why the ProLine pairs with almost any system.
