As Useful as a Dead Headphone
These plugs only reduce 25 db as answered by the seller in the questions section on November 15, 2018.  Normal conversation are 50-60 db.  These earplugs are made of thin silicone and nothing else.  I hear all sounds very clearly (even my fan's white noise) with these plugs on, and I tried them all and I pushed them into my ear as I far as I can.  I can't imagine how the seller can claim it's good for concerts.<br /><br />If you have a pair of dead headphones, use them.  That is about the same level of db reduction you get from these silicon earplugs.  These are a waste of money since I already squished the mold-able ones and it's no longer in 'original' condition for refund.
