I tried five wireless Blue Tooth headsets (Plantronic, Logitech, Samsung, Jabra, etc)and none worked very well -- with one issue or another. Some sounded tinney, and all carried lots of road noise. So the people on the other end always complained.In stepped in the BlueAnt Bluetooth which I read about as Gadget of the Week in Barons. The device works very well. I simply leave it on the magnetic holder provided which rests on the Visor. I can hear the caller very clearly. The device is especially good at boosting the volume level. So I can turn the volume up and hear even the softest voices while traveling on the highway. On the other side of the call, the callers tell me that the voice quality is pretty good, with a hint of echo sometimes. Most important, they don't complain about road noise.I leave the device in the car all the time, and recharge it about once a week. The on-off switch is great. You flip the microphone down toward you and it is ON. You flip it back flat into the device, and it is off. So there's never a mystery about whether it is ON or OFF.I highly recommend this device for anyone who uses the cell phone while driving. Keep in mind that this device is essentially a speakerphone in the car. So everyone in the car will be able to hear the conversation, and everyone in the car is able to speak to the person on the other end of the call. So anyone who rideshares to commute may have issues with this feature.
