These are substantially better than I had expected. I am using them for a noisy, distracting office environment. I know that's not what they are really for, but I took a chance anyway. WOW. I cannot hear a thing. I can't hear the copier, others shuffling about, etc... I cannot hear the person standing 3 feet away talking directly to me. I can't hear them AT ALL. I figured they would muffle voices and noise better than the foam ear plugs but there is no muffling at all...I literally cannot hear a thing. I swear I live in a sound-proof box now! It's like someone found the MUTE button!!!
I've always had some trouble with regular ear buds (like music ones) hurting my ears so I went for the small, instead of the medium, which is for "average" folks they stated. They are a perfect fit. The medium, I think, would have hurt my ears. (I'm a Caucasian woman, on the thin side, for a reference point.)
These go in so easily (not like the stupid foams ones that you have to roll up and shove in quickly and hope it seals, only to do a crappy job anyway)! And the outer part of the ear bud fits perfectly into my ear, securing it into place. There is no way to have these not in far enough or in too far. They are perfect.
