Description
The Poly EncorePro HW510V/HW520V Replacement Voice Tube (85Q39AA, part 88767-01) is the genuine spare voice tube for EncorePro HW510V and HW520V headsets. The voice tube channels sound from the user's mouth to the microphone capsule at the boom base — when it becomes blocked, bent, or damaged, microphone quality degrades noticeably. Replacing the voice tube is a quick, tool-free fix that restores clear outbound audio without replacing the headset.
