The CC-300 and CC-400 headsets can be easily adjusted to accommodate the preference of any user. The microphone boom has a 300° rotation to allow the microphone to be worn on the left or right side of the head. Users can make the headset larger or smaller by using the slide adjusts on either side of the headband. Cushioned with super-soft leatherette padding, the headphones sit on the ear to provide a comfortable fit for users. A rotating, flexible gooseneck is included for optimal positioning. Integrated Mute Switch Operation.The CC-300 and CC-400 headset microphones can be turned on and off by moving the microphone boom. To turn ON the microphone, pull the boom gently downwards (past the 10 o'clock/2 o'clock position). To turn the microphone OFF, push the boom gently upwards (above the 10 o'clock/ 2 o'clock position). The CC-300 and CC-400 headsets have been designed so that the cabling and connector type can be adapted quickly to the application. Users can order cables with different XLR connector choices and appropriate pin-outs. To change the connector cable in the field, simply disconnect the cable from the headset and exchange the cable with a standard Phillips screwdriver. The same process can be used to repair and replace a damaged cable on the fly.
