Absolutely, utterly, phenomenally, completely useless! This is a slightly different design than the Jabra that I have used for years and, being the same brand of device and just a slightly different looking design, I thought that it would be comparable....NOT!!! All I get from the people I am trying to talk to is, "What?" and "Where are you? What's all that noise?" "What?!" I highly recommend AGAINST anyone buying this piece of junk and I think that Jabra should be ashamed of themselves for selling it!
