I have used a HW520 at work and like it. We have since moved on to wireless headsets.
My mom wants a headset for her Panasonic cordless phones as she sits and talks for hours to her sister.
Is is possible to adapt a HW520 to 2.5mm for use with a Panasonic phone
The handset model number is KX-TGA660 which is part of a set with basestation 5 handsets with chargers. I am not sure of the model number of the set.
Similar headsets would be OK but a 520 with any necessary adapter is about all I want to spend. A dealer suggested a higher priced Jabra but, I know Plantronics/Poly and know very little about Jabra plus the she only recommended even higher price headsets.
