Reduce volume without significant negative affect on clarity.
This is the second pair of these that I have owned/purchased.  Used primarily for watching movies in theaters and they do a great job of reducing volume without dulling the sound too much.  Speech remains clearly audible.  If you watch a lot of movies and find yourself walking out of the theater with &#34;fuzzy&#34; ears I can't recommend these enough.  I've also used them for concerts and they are quite good for that use.  If you find that volume is reduced too much you can just pull them out a little bit for a looser fit.<br /><br />They are far, far superior to standard earplugs for quality of sound, and if you value your hearing long term the slight reduction in clarity is well worth it.
