The Plantronics CS540 wireless headset uses the new 1.9 GHz voice-dedicated frequency which provides users with strong sound quality for optimal voice and hearing clarity.

Using the new voice-dedicated 1.9 GHz DECT standard frequency, business professionals don't have to worry about interference from nearby Wi-Fi networks, cordless telephones, and other wireless office equipment common on other frequencies. The result is a less crowded radio frequency that provides superior audio clarity with no interruptions.
