POLY EncorePro HW510V/520V Voice Tube | Office Headset Accessory

Keep compatible POLY EncorePro headsets ready for daily calling with a replacement voice tube built for the HW510V and HW520V platform. When voice performance starts to drop from wear, replacing the tube restores the acoustic path that supports clear speech capture and dependable call handling. This accessory is a practical choice for IT teams and workplace operations groups that standardize on Poly headsets and want to extend the service life of deployed devices. Instead of retiring a headset for a single worn component, you can return it to service with a targeted replacement that supports continuity across contact center, reception, and office communication environments. For organizations managing headset fleets, small parts like this matter. They reduce avoidable replacement spend, keep users productive, and help maintain a consistent audio experience across the desk. The result is a lower-friction support model for teams that value uptime, predictable maintenance, and controlled hardware costs.
