If you want your Plantronics C540 or your Savi 7210/7220 wireless headset to be compatible with your computer in an easier way possible you can get the APU-76 adapter, pictured below.
This adapter is an easy plug and play solution for your CS or Savi desk phone wireless headset. One of the ends gets plugged into the base of the wireless headset, the other into any of your USB-A ports and the computer will recognize the headset as an incoming and outgoing sound device. If you need to make basic adjustments you will need to go to the Sound settings on your computer, but if you need to make advanced adjustments like side tone or notifications you will need the Poly Lens software on your computer and up and running. The Poly Lens can adjust not only volume and call controls or notifications, but can let you know battery talk time in real time on the screen of your computer.

Jabra Wireless Headsets
For Jabra users the transition would not be as easy as with Poly/ Plantronics users as the Jabra Pro 920 wireless headset was designed exclusively to be used with desk phones 
only. If this is your case and you love Jabra quality, perhaps would be a good time to
upgrade your wireless headset to the Engage 65 or Engage 75 wireless headsets. These headsets offer a really comfortable wearing style, in either Mono light weight headband, rich stereo sound quality or ultra light over the ear ear hook with a really discrete microphone boom arm.

Built in busy lights are found and more noticeable for piece of mind when on a call and having to let people that you are busy without the need of doing gestures or shutting doors. The Engage family will be recognized by the computer as a incoming and outgoing sound device and basic setup can be controlled from Sound settings of the computer. Advanced customization can be found using the Jabra direct software, letting to increase the wireless range, adjust the side tone, customize the turn on or off of the busy light among others. The Engage 65 and 75 are designed to be used with desk phones and computers, however if you only
need a wireless headset for your computer the Engage 55 would be your way to go, thanks to its Link 400 dongle allows you to have a similar range as the 65 or 75 without all the base and with a more discrete interface that is accident tolerable as its bendable, allowing to leave the dongle plugged in when traveling.
