After 16 hours researching Bluetooth audio technology and Bluetooth receivers (including three hours dedicated to researching portable models), we spent dozens of hours using 10 portable models, and four additional hours conducting in-depth testing. If you want to add Bluetooth connectivity to your current wired headphones—either because your phone lacks a headphone jack, or because you just want to be able to listen to audio without a direct wired connection to your phone, tablet, or computer—the BlueAnt Ribbon is the best choice for most people.
