Sound quality seriously deteriorates with activation of the volume boost (the reason I purchased it).

Most of the "expensive" stuff had obviously been put into making a phone with superb voice quality and I can tell you that it's not wasted.

The phone speaker was loud but quality was terrible

The build quality of the phones is also excellent although the handsets are a little weighty

There are also multiple tone settings that are really great at improving the voice quality

Good sound quality

Not good quality

Bad sound quality (sometimes garbled).

The volume is definitely there, but sound-quality is mediocre or slightly above (no matter what tone-setting you use)

Bought it fore my mother who is hard of hearing and this phone has defintely improved her quality of life.

Excellent quality and loud enough for elderly parents.

Truly excellent quality and performance!

What I used to attribute to her "slipping" was actually poor sound quality and she was faking her end of the conversation

My only issue is that the sound-quality (both on the handset and the speaker) is not as crystal-clear as I was hoping it would be

The set-up was easy and the sound quality is very good.

Before that, nice quality sound and grandmother loved that the light flashed and announced who was calling.

A very common problem is harsh quality of sound, which seems to be inherent

Sound quality seriously deteriorates with activation of the volume boost (the reason I purchased it).

The sound quality was terrible and on top of that, it was very difficult and complicated to use....absolutely the wrong product for an elderly person with even slight cognitive impairments.

Even when they were working the sound quality was not that good

The sound quality, which is why we buy these units, is much clearer and are aided by better tone adjustments

Add to that, poor sound quality, and there's not much to recommend about this phone.

I probably would have returned it even had it worked as overall perceived quality was poor.

they guys that he plays cards with and he has a much better quality of life with this phone.

I liked the sound quality and adjustability

The sound quality and volume are not good enough

works as they say, which is what my husband need.

This phone is as close to perfect as I could find

Volume is loud but the clarity is not as clean as I would have liked
