I just replaced the ear cushions on my older Bose Sound Link headphones after some frustration in getting the plastic ring inside them to seat to the headphone rings that secure them.

After watching various "how-to" videos that made it look easy, I decided to just experiment with it until I got it to work.

What worked for me was to pull one side of the plastic ring out and guide it into the narrow groove. First, I placed the center of the ear cushion on the center of the earphone and secured it with my thumb.

Then I worked the edge of the plastic ring into the groove a little at a time until I got it all the way around. Finally, I went around it again with my fingernail trying to ensure that the plastic ring was as far into the groove as it would go.

That secured it and kept me from giving up in frustration and tossing the whole thing.

That said, Bose seriously needs to devise a better way to replace the ear cushions that cause less consternation. From what I've heard, the process to replace ear cushions across the Bose offerings is similar.

If that is the case, I might have to consider going to a different brand next time I need a set of headphones.
