Designed to be used with UltraLITE HUB full duplex wireless intercoms, this Eartec Max4G Headset is single-eared and features a 4-pin XLR female connection point. Its headband is fully adjustable and its leatherette earpad fully encompasses the ear, thus providing a firm yet pleasant fit. Its on-board dynamic microphone sits at the end of a boom arm which can swivel 270°. Also, rotating the microphone into a fully upright position-parallel to the headset's headband-automatically mutes the microphone, ensuring a more convenient way to kill the signal to the mic rather than fumbling for a button on a beltpack. Lightweight at 5.0 oz, this headset sports a 3' cable. Box Contains Eartec Max 4G Single Headset with 4-Pin XLR Female Connector 4 Pin XLR Female ConnectorLimited 6-Month Warranty
