The original ear pads on my (2016) Bose headsets had become degraded with use, particularly over summer since leather-like coverings and stinkingly high heat and humidity don't mix. On one of them the yellow foam was popping out from under the covering. Bose is not exactly known as an "economical" brand and I originally thought that I would be up for a significant repair cost.
Then I found these, with a surprisingly reasonable price.
The first thing that impressed me when they arrived was the instructions. They were clear and easy to follow. The second was the quality of the material. The coverings are every bit as good as the original, possibly even better in terms of comfort. There seemed to have slightly more "give" than the original material, but still sealed out external sounds capably.
I'm sure that they won't last forever but I'll be back for another set of these if and when I need to.
