The portable Bluetooth speakerphone has been around for some time now, but no company has been on the forefront of technology more than Supertooth. Their newest device - the HD - could top the cake. It's a bit larger than your normal device, but the standard calling and pairing features are very user-friendly and make up for any hesitation you may have. A great feature for families on the go is being able to connect two phones simultaneously. The dual microphone, 5.4-watt amplifier and speaker is controlled by a scroll wheel. The HD has a noise canceller that actually works effectively with the windows down. The Supertooth HD is one of the most advanced Bluetooth speakerphones on the market today, and an added bonus, you can update your facebook and twitter site, just by using your voice, safely while driving with two hands on the wheel. With the Dial 2 Do service, stream music from your phone, follow your GPS directions and even composing texts and emails are simple with voice commands. The Supertooth HD is in stores now.
