When to replace the cushions
Typically, ear cushions should be replaced every six months or every 350 hours of use. They may need to be replaced more often if worn over facial hair, subject to extreme temperatures or stored in a way that puts force on the cushions. If the cushions are flaking, torn or flattening, it is recommended to replace them to restore the effectiveness of the seal, which impacts noise-cancellation.How to replace the cushions
- Grasp the ear cushion skirt where it folds into the slot on the earcup
- Gently pull the ear cushion skirt up and away from the earcup
- Align the replacement ear cushion with the earcup
- Tuck an edge of the ear cushion skirt into the slot behind the earcup cushion flange
- Gently stretch the cushion around the earcup, working the skirt into the slot as you go
- Grasp the ear cushion and adjust its position to remove any folds in the skirt
