The mVox Duo Communicator aims to combine both a Bluetooth headset and a Bluetooth speakerphone into a single, portable device. One of the first of its kind, the mVox Duo Communicator can act as an all-in-one Bluetooth headset, VoIP headset, handsfree car kit, and mobile conference phone. It also comes with voice-recognition software that you can use to program all sorts of voice commands to the headset. This essentially adds voice-command capabilities to any cell phone, which is great if your cell phone doesn't have that feature. Unfortunately, the mVox Duo Communicator is bulky, clunky, and an altogether unattractive device. That said, if you want a multifunction Bluetooth communication device, the mVox Duo Communicator may be well worth the $250 you'll have to pay for it.
As we mentioned, the mVox Duo Communicator doesn't have a lot going for it in the design department. Measuring 3 inches long by 1.2 inches wide by 1 inch deep, the Duo Communicator is quite possibly one of the largest Bluetooth headsets we've ever seen. It has a mostly silver-and-gray design, which is fine, but the model we received had silver paint chipping away everywhere, making it look a little cheap.
On the front of the headset is a blue LED that flashes when the device is turned on. On the right spine are the power/mute button, the Headset Talk button, and a charger jack, while the volume rocker is on the left. On the back are the earpiece and a speakerphone button, which also houses a red LED that flashes when the speakerphone function is activated. There's also a rubbery flexible ear loop that can be adjusted to fit either ear. All the buttons felt a little spongy, but they were still very tactile and can be pressed easily. While the headset fit just fine around the ear, its large size and weight feels really awkward when worn on the side of one's face, as if it were weighing down our ear.
If you wish to use the mVox Duo as a speakerphone, all you need to do is insert the headset into the included black holster. The holster has a large clip on its back, which you can then clip to your shirt, to, say, replace a handsfree car kit. Once inserted, the speakerphone is immediately activated. In order to return to headset mode, just remove it from the holster--it's just that easy. In headset mode, you would use the Headset Talk button to make, receive, and answer calls; while in speakerphone mode, you would use the speakerphone button instead.
