You twirl them into a smaller thickness and they gently expand once you insert them.<p>I started using them a number of years ago when the guy in the house next door got a very loud dog that he insisted stay outside at night and&#x2F;or early morning. So of course the dog did nothing but whine and bark! Fortunately he finally got rid of the dog.<p>A single &quot;disposable&quot; pair of plugs can last a week, or even a month if you want. The sound effectiveness decreases slightly over multiple uses. But that&#x27;s OK. They start out really quiet, they claim something close to 30 dB. So if they&#x27;re only 15 dB after multiple uses, that&#x27;s OK. You probably don&#x27;t want total isolation anyway.
