Summary: I feel it could amplify the sound more, it doesn't seem loud enough to me. Now I know I'm older and having a problem hearing, but from start to finish there is not a big difference in the sound!
Summary: This is the second time I have purchased this phone for my Mom. First one lasted many years but one day no longer worked. In haste to replace it, I bought a regular phone that got dropped on the floor due to it's feather weight.
Summary: My dad has trouble hearing the callers on his present phone and this seemed like an easy way for him to be able to hear them. The phone doesn't really amplify much unless the BOOST button is pressed for each call. The ringer was no louder than his old phone. Save your money and buy something else.
Summary: This phone is ver easy to use and comfortable to hold. I wish it had an adjustable ringer a sir is too loud. The boost button adds a lot of volume when needed. It does not work well with my hearing aid telex oil but I do not need it with the boost button anyway. I'm very pleased with the phone.
