Learn more about Office Headsets

The standard wireless office headsets, such as the following models, all use a 1.9 GHz DECT Technology:

• CS70
• CS55
• CS351
• CS361
• CS361N
• CS351N
• GN 9330
• GN 9350
• GN 9120

This is a different frequency than standard wireless office products (which normally run at 2.4 GHz). Therefore theses headsets will not interfere with your other wireless devices.

Conversely, all mobile Bluetooth headsets use the 2.4 GHz frequency, but they also include technology to avoid interference with wireless networks. A Plantronics headset will meet the Bluetooth v1.2 standard which includes adaptive frequency hopping. This standard determines if there are other 2.4 GHz devices and prevents any interference.
