I have a very old Plantronics headset that has a plug that fits an old cordless phone in my home. The original ear cushion started to come apart in my ear, so I bought this one. It fits well and the headset works great, so it is like having a new headset for the price of the ear cushion!
Ear cushion of 10 years was showing its age in many ways. Selected to replace and new one was exactly what was needed. It answered all our needs for fit and comfort. Process to obtain was easy and would recommend it to others.
