Review on Plantronics Ear Cushions Leatherette 2 by Gillian Ahn

Despite many incorrect answers from the seller/manufacturer, this item will NOT fit the Plantronics CS520. These pads are too small. Measuring just over 2 inches in diameter and 1.5 inches in diameter, the pads for the CS520 are non-stretchable. If you are looking for pads for the CS520, look for part #71782-01. DO NOT BUY THESE PADS if you have a CS520 as they will not fit. Also, when I arranged the return, the seller sent me a prepaid shipping label with the message that they would honor the maximum allowable return fee and return postage. Given that this item is $5 it would be easier to just throw it in the trash instead of sending it back to the seller to scam another buyer.
