Treat your headset like you would treat your stereo and computer at home. Headsets can't take lots of abuse. Always unplug your headset by the quick disconnect plugs and do not pull on the cords. Never use alcohol . Plastic parts dry out or fray when exposed to alcohol based products.
Cords can easily become damaged if caught in desk drawers.
A. Headset amplifiers have a built in audible warning for low battery power. It operates much like a normal handset on your desk phone. If there is ambient or background noise around you, then that noise is transmitted over the telephone. It is recommended that if you work in a call center environment or share a common work space, then using a noise-canceling headset will increase the clarity between the caller and yourself.
