They broke after 5-10 uses. Just buy normal foam ear plugs.
I used these Downbeats earplugs 5 or 10 times. They were a bit small and hard to put in and take out. They provided an inconsistent seal and inconsistent noise reduction. After 5 or 10 uses, the plastic stem on one of the earbuds broke, and it got stuck in my ear the whole night, until I could get tweezers to take it out. Now it's not really usable, because you can't put it in, take it out, and it doesn't really block the sound without the plastic stem.<br /><br />Subsequently, I bought several other brands, and you can see how I've rated them in the picture.
