Yes it is very useful and portable
So useful. They cut out a range of frequencies so that you can still hear people but it cuts out the painful ranges of the music in a club or concert. Or the tremendous roar of monster truck rallies.<br /><br />The ear plugs are quite discrete and not blatantly visible. It does take a few tries to grab the little pin to pull them out.<br /><br />The portability makes it very good for impromptu outings that normally have you cringing at the loudness.<br /><br />The container is small, metallic, and kind of resembles a &#34;pill case by Axe&#34;.<br /><br />Short answer, a nice little thing to have on your key chain.
