They have made a huge improvement in my hearing.
I loved them right out of the box.  So much that I ordered a second pair. The price is right.  I have extremely small ear canals and was unable to get the very small tips I ordered installed.  There for they stuck out of my era a bit and fell out a couple of times.  I was going on a long outing so hhis morning I put just a tiny piece of double sided medical tape on them and they are staying put. I recommend it, it works like a charm.
