Plantronics WH500 is a spare or replacement headset with its own charging cradle for use with Plantronics wireless models Savi WO1, WO100, W440, W740 and W745.
If replacing your old headset on a WO1, WO100, simply detach your old cradle from the right side of your base and snap this cradle in its place.
If you are using this in multi-shift, shared phone applications where a second headset is needed for second shift, then you must also get the charging base
so this unit can stand alone and charge, apart from your main base. The charging base includes its own AC power cord. Please see below.
Note that this replacement headset is packaged with ear hooks, headband and ear gels.
