Having wasted my time and money on the Plantronics 520 without much interest from the customer service team at Plantronics either, I was wary of purchasing another bluetooth headset to be honest. However, I have to admit to being very happy with my new Jabra BT2020. No problems whatsoever and for almost a third of the price of a useless headset from Plantronics. Don't be put off by the price. Fits well on the ear too. I only use mine with my laptop but that works fine. Plantronics tried to persuade me that the fault probably lay with me using a Belkin bluetooth dongle. Knowing Belkin's products as I do, I thought it highly improbable. I was right. Thanks again Plantronics for a useless product and after sales service.
