I’m often asked for my recommendation for a good quality headset to use along with a Cisco SPA5xx Desk VoIP telephone. I will expand this page with further options, but for the time being I will list one of my favorites. I will provide a link to eBay which will give you a much better deal than buying brand new.
The beauty of the new Plantronics Savi model line is that the base station connects three different ways simultaneously: To your desk phone, via bluetooth to your mobile phone, and via USB to your computer. Or you can just use it to the desk phone by itself. You can roam 350 feet from the base station, and press the button on the side of the headset to answer/end the call. There is a special cable that I list below that you need to get as well, which allows the headset to communicate with the Cisco phone.
I would suggest the Plantronics W730 headset. Just click on the image of the model you want to check the latest prices for. But, you will need to get this cable no matter which one you get: Plantronics APC-45 cable
