I had a jabra BT 500 and loved it, I could wear it all day and the eargells fit well inside my ear providing great sound. Unfortunately, I inadvertently left it in the charger for a week and fried it. I decided to replace it with the BT5020 which Jabra advertises as the follow-on model for the now discontinued 500. The BT5020 does not fit nearly as well around the ear and the new style eargells are flimsey and do not fit inside my ear.I returned the BT5020 after playing with it for a few minutes and ordered a Jabra BT 530, which I started using today; so far so good. It fits much more comfortably than the 5020 and I am told that it sounds clear to people I am talking to
