We do not have the replacement pads per se, but we have other ones to try
- Our best fit, for all 3 of these headsets, tends to be the Leitner leatherette ear pad (Cat# 2497 on website)
- The DeskMate ear pads CAN fit, however they are thick and may make charging difficult when headset is attached to the headband
Note: The cushion for the CS540 just stretches around the base of the headset, there is no detachable ring, though you can pull off the ear pad and replace it with another. The CS510/520 have a detachable ring that would need to be placed into the cushion, then the ring snaps on to the headset.
