Description
The Poly EncorePro HW540 Large Replacement Ear Cushion (85R21AA, part 88832-01) is the large-size leatherette ear cushion for the EncorePro HW540 convertible headset. When the original cushion has worn, flattened, or degraded from regular use, replacing it with this genuine Poly part restores the acoustic seal and wearing comfort of the original headset. Leatherette material is durable and easy to wipe clean — particularly useful in shared-headset environments.
