The sound is loud and clear and the range is good, so I have no complaints.

Work well with good range

The range is very good

The range away from the base unit has been outstanding, not only throughout the house but also anywhere in the yard around our three acre property

The batteries hold a charge a good, long time, they have a pretty decent range (I love to walk in circles in my yard while I'm talking on the phone), and I am starting to really like that they talk to me to tell me who is calling.

I don't think it says it supports that range, but I was surprised that it connected without having to set it even in the room with the base unit

Although the range is good, there are limits, so I'm careful to leave my smartphone in the same room as the home base, and it works like a charm

Works very well, good long range operation between Handsets, better than ATT.
