The best thing about the Zum Maestro USB/BT Combo Headset is its dual use: Softphone using USB for VoIP apps on your PC/Mac computer, and using Bluetooth to pair with your phone or tablet (iOS or Android) or computer (Mac/PC). And if you have a Deskphone with Bluetooth capability, it will even work with that! However you use it, the Base has the connectivity so your headset is always wireless.
The comfortable headband wearing style, with extra-large leatherette ear pad, is ideal for those spending a lot of time wearing a headset.
