Longtime user of Jabra BT200 with two years of great use -- most of time people didn't know I was on a Bluetooth. Thought the BT5020 better looks and better claim of wind resistance was a great upgrade. Big mistake. More wind noise, and constant buzzing on the line. Constant "What did you say?" from the moment of use from anyone I called. New ear style is comfortable, but the darn thing does not lock and rotates every time you put it on. I have replaced with a Jabra BT250V, the replacement for my old model -- Back to great sound on both ends.Sorry to see Jabra sound quality bad on the new model, but stick with the 250V!
