We purchased one of these for my Blackberry pearl and it worked great for awhile and I even recommended it to my Wife. When she got hers it wouldn't play sound and when we called BlueAnt they told us her phone wasn't compatible with it. But mine worked with her phone perfectly! Amazon was awesome and sent us a replacement which worked perfectly until the part that goes in you ear just broke off. Again Amazon was great and gave us a refund, but shortly after that mine for my Pearl stopped working and I could no longer hear sound from it. We are going back to the Motorola 500 which has always been reliable for us.
