Now You Can Connect Your Plantronics CS540 To A PC. Here’s How.

CS540 connected to PC

Anyone who’s purchased a Plantronics CS540 wireless headset knows it doesn’t work with a PC, only a desk phone….until now!

This blog will provide you with information on a new product designed to allow the Plantronics CS540, a.k.a. the Plantronics C054 to work with a PC or MAC.

In the past, the C054 wireless headset has been limited to use on a desk phone only. For those who upgraded to Softphones and discontinued using desk phones, the CS540 wasn’t able to be used on the new platform. This meant that CS540 users were required to purchase USB compatible headsets and eliminate using the CS540’s. This can not only be expensive but it also doesn’t allow the customer to get maximum use and value from the investment they made into the CS540 headsets.


Finally, there’s a solution to this problem.



The Plantronics APU-75 UC Adapter can be used on the following Plantronics CS500 series wireless headsets:

The APU-75 can also be used with the following¬† Plantronics CS500 series “XD” 900 MHz wireless headsets.
