Summary: I love them when they work. But every time I've bought one, it fails within a couple of months. I've been able to return and get a new one in the past, but am undergoing that again! One I understand, but failure rate is now over 50%... If it's good, it's good until I lose it! But I keep buying them because when they work, they work well.
Summary: I bought this due to the good reviews on this site but after two weeks I returned it. I found it was too loud out of the box as well. I had difficulty understanding people about half the time and I returned it for this reason. The voice commands were interesting and I like the feature where it announced the caller.
Summary: Out of the box, this unit was too loud. Too loud to listen to & volume on other end of call was too loud as well. Excellent noise cancellation, but after a few weeks I had to return it. I picked up the Logitech Legend & am very impressed.
