I agree with other reviewers that the quality of this phone in terms of being able to hear and be heard is poor enough to warrant returning it. To best describe the quality, I would say it's like talking on a speakerphone even when speaking directly into the handset. There are odd fluctuations in the volume levels of what you can hear, there is static whenever you speak, there is eerily dead silence when the conversation pauses and there is a very faint echo of everything you say. People on the other end of the call also complain about the quality. Using a headset did nothing to improve the situation. This is all too bad because the design of separating the base from the handset is perfect for me. And the fact that using the phone doesn't disconnect my wireless internet connection as my 2.4GHz phone did is great. But I guess I am willing to put up with that to return to the excellent sound quality of my 2.4GHz Uniden telphone.
