Review posted March 2008 by Cedric Bosch

The BlueAnt Supertooth Light is an external Bluetooth speakerphone- nothing more, and nothing less. If you are satisfied with your current cell phone's built-in speakerphone, this product will probably be of little use to you. However, there are plenty of cell phones on the market that have a terrible speakerphone, or no speakerphone at all. This makes using the phone in your car difficult, or in some states, illegal. The Supertooth Light attaches securely to your car's visor and pumps out your caller's voice through a powerful speaker. Plus, the Supertooth Light has noise-cancellation technologies that make for a clearer call than the majority of cell phones can provide. The best thing about the Supertooth Light is that it is completely self-contained, so there are no wires or power adapters to worry about. You can easily transport it from your desk to your car in the morning, and back again in the afternoon. The BlueAnt Supertooth Light retails for $99.

BlueAnt Supertooth Light


The Supertooth Light measures 4.8 inches long by 2.4 inches wide by .7 inches deep- slightly longer than a stack of playing cards. This device holds true to its name, too, tipping the scales at a mere 4 ounces.

The Supertooth Light is one sleek, well-constructed portable speakerphone. Unlike other external speakerphones, the Supertooth Light is something we'd actually be proud of having in our car. Its glossy black finish is svelte and exudes professionalism, while its modern rectangular design means it will have no problem blending in with luxury car interiors. The Supertooth Light's build quality is excellent, but somehow it manages to weigh less than most wired speakerphones.

Pairing and Features

Using the Supertooth Light entails extending the built-in microphone extension... and that's it. Just push on the microphone stick to pop it out, and the Supertooth Light automatically powers up and pairs itself with your Bluetooth-enabled telephone. We really could not have asked for a simpler process- BlueAnt really nailed the design on this one.

There are only two buttons on the speakerphone: a green one to receive calls and a red one to end calls. Our only gripe with the Supertooth Light's interface is these buttons- they are somewhat soft and difficult to depress, especially when mounted to your car's visor. Next to these buttons are the Bluetooth and charge indicator lights. These lights will let you know when the speakerphone is in pairing mode, when it is connected, how long it has been charging for, and will blink red when the battery is running low.

Audio Quality, Voice Quality, and Range

We've said it before but it bears repeating now- the Supertooth Light just plain works. Its duplex speaker system is crisp, clear, and loud- about the same as a pair of typical laptop speakers. Talking on the phone in the car became a pleasure again, as the hassle and danger associated with cords disappeared completely. When using the Supertooth Light, we felt like the person we were talking to was sitting right beside us. Outgoing sound quality was remarkable as well. We tried repeatedly to get the Supertooth Light to send static and wind noise to our callers, but our efforts were in vain- no amount of blowing into the microphone or yelling loudly made any difference. It's easy to tell that BlueAnt really spent some time refining the Supertooth Light's audio design to make it work perfectly.

Your phone connects to the Supertooth Light like a Bluetooth headset, which means you can perform the same functions with the Supertooth Light as you would with a traditional Bluetooth headset: answering and ending calls, voice-dial, and last number redial.

BlueAnt Supertooth Light

When working with Apple iPhone, Motorola RIZR, and RIM BlackBerry 8800

We always test our Bluetooth peripherals with a few different phones, since each device seems to work differently depending on the phone with which it's paired. We tested the Supertooth Light with the iPhone, the RIZR, and the BlackBerry 8800, and are pleased to report that the Supertooth Light performed indistinguishably- and perfectly- on each cell phone. Since the Supertooth Light's DSP processing is done in the speakerphone itself, the phone's hardware is irrelevant to call quality. The only differences we noticed were in range- we got 13 feet with the iPhone, 11 with the RIZR, and 15 with the BlackBerry. That said, you probably won't need more than 6 feet of range if you are using the Supertooth Light in your car.

Battery life

The Supertooth Light is rated at 15 hours of talk time. We were able to squeeze an impressive 13 hours of talk time out of the speakerphone, which is more than enough for a week's worth of commuting. You can charge the Supertooth Light using the included AC or car charger, or with your PC using a USB cable (not included). The Supertooth Light usually takes less than 2 hours to charge completely.


If you are disappointed with your cell phone's speakerphone, look no further. The BlueAnt Supertooth Light is a fantastic device with outstanding call quality, a powerful speaker, and long battery life.
