Ideal for professionals who wear compatible headsets for extended periods and need fresh pads. Users of other headset models or those requiring leatherette material should look elsewhere. The kit only suits the specific HW510 and HW520 series listed.

Pack contains two foam cushions

The package quantity of two pieces provides a complete set for both ear cups. This single spec determines if the kit matches your replacement needs. Verify your headset model is HW510 or HW520 before ordering. No other hardware is included.
