If an ear cushion becomes detached from the earcup or you need to replace the cushions, follow these steps:
Ear cushion replacement (video included)
- QuietComfort® 3 Acoustic Noise Cancelling™ headphones
- Check to ensure the headphone power switch is in the off position
- Align the two holes on the back of the cushion with the two posts on the earcup
- Push the cushion onto the earcup
- Press in around the outside edge of the cushion to snap it in place
Make sure the cushion is flush all the way around and that there are no gaps between the cushion and the earcup.
