| Bottom line | The power of the sun means that you'll never have to think about charging the Griffin SmartTalk Solar. | The Plantronics K100 delivers great-sounding,
hands-free calling on both ends of the line, and its FM transmitter is a nice bonus when it works, but look elsewhere if your phone is one of the few that don't support voice-activated dialing. | The SuperTooth Crystal is a simple Bluetooth
car speakerphone, relying largely on your smartphone to do the heavy lifting, but it has a few tricks up its sleeve to make it easy to live with. | Info unavailable | Info unavailable |
