When you have a Multi-line telephone system and you spend many hours each day discussing while trying to support the device against your ear, a wired headset will provide automatically interaction allowing you to easily write or type and also reduce neck and neck stress. Multi-line phones will use any of the standard Plantronics H-series headsets and either an amplifier or immediate link wire will be required.
Plantronics Wired Headset
The wired headset fits on your head or ear and has a cable clinging down that amplifier or immediate link wire will affix to. This relationship is called a quick detach and allows you to keep the wired headset on and quickly detach from the amplifier or immediate link wire and walk away from your table. The other end of the amplifier or immediate link wire has a flip relationship that will connect into your desk phone or computer slot or wherever you connect your wire headset.
