Keep Poly EncorePro HW510/520 headsets performing as intended with replacement foam ear cushions built for frequent daily use. When ear pads compress or wear down, comfort drops and the headset can lose the stable seal users rely on for long shifts. This 2-piece replacement set restores the feel of the original fit, helping maintain consistent contact against the ear and a more comfortable wearing experience. For organizations running support desks, customer service teams, or shared headset pools, replacement cushions are a practical way to extend the service life of existing hardware without replacing the full headset. Foam construction keeps the profile light and familiar, while the matched design supports quick swaps during maintenance cycles. It is a simple accessory, but one that protects user comfort and helps preserve the value of the headset investment. Choose this replacement set when you want to keep deployed Poly EncorePro HW510/520 units in circulation longer, reduce wear-related complaints, and maintain a cleaner, more consistent user experience across the team.
