Just didn't work
Two stars for the nice case and tether, but in the end don't block any noise. Bought these as an improvement over the foam plugs to lessen the sound of my wife (and dog's) snoring. I could put them in far enough that they were uncomfortable, and it sounded no different. The stems look like they stick out far enough to be a nuisance but they are quite flexible and that was not an issue.
Rating: 2 stars
