The phone has a very clear sound, even for my hard of hearing mother. This phone has every feature that a person could ever need. The drawback is that the talk button is too small and not placed in a convenient location, this talk button needs to be pushed to both answer a call and make a call a design change should be made on this to make it more user friendly.
I'm hearing impaired and this phone helps me to hear more clearly. However, at age 86 it is difficult for me to learn how to use it. Too many steps to navigate, not very intuitive. I find the "slow" feature very helpful.
I find it too difficult to program and so far am unhappy as it often does not really help my hearing. I am very senior and was hoping for better hearing/understanding on the phone. I will keep working with it for a while.
