Earcup Extensions for Bose QuietComfort Headphones

The cushions on the Bose QuietComfort headphones weren't thick enough to prevent my ears from pushing up against the internals, leading to pain after a few hours of wear. These extensions provide a little more room to prevent that problem. They snap directly onto the headphones, and the ear cushions snap directly onto the extensions.

These work on both the QC35 and QC45 models. I believe they should also work on the QC25, but I don't have one to test. There is no effect on the sound as far as I can tell, but I'm no audiophile.
