Poly CS540 Leatherette Ear Cushions (85Q20AA) are replacement cushions for the Poly CS540 headset. They provide the headset’s ear-contact pieces in a leatherette finish, making them a practical choice when the existing cushions need replacing.
The pack contains two ear cushions, enough for both sides of the headset. Their CS540 designation identifies the headset they are intended for, while the leatherette material describes the cushion covering. This is a focused headset accessory supplied as a pair.
