OK. But not any better than foam plugs
I got these mostly to wear around my shop area, cutting, sawing, using power tools. You get the idea. And they're ok. They work as well as the small foam plugs you squish and put in your ears, I suppose. So where does the 3-star rating come in? Well, for what they are, they're expensive. You can get 50+ pairs of the foam plugs for less and, when you're done, you toss them. Not sure what the allure of these is at this price point. I definitely wouldn't sleep in them, especially if you're a side sleeper. That would be very uncomfortable.
