I have had my Jabra BT500 for three weeks and am already returning it to the company for a replacement. The speaker has stopped functioning. It went dead between two calls. It is still pairing with the phone, and the mic works, too, I just can't hear anything.The sound quality of the Jabra headset isn't as good as my wired headset, but for day to day use, it is far more convenient. Most people say they can hear me just fine, but at least two clients have mentioned that I sound like I am talking in a wind storm. Although the literature claims a range of 30 feet, it is more like 7 feet. The phone must,also, be kept on the some side of my body as the headset.I hope the new one works better.
