Talk and drive: BlueAnt Supertooth 3 hands-free speakerphone

More and more US states are passing laws that forbid drivers to use handheld mobile phones, but fiddling around with the buttons on a headset can be equally distracting. If you must talk and drive, BlueAnt has a better way: the voice-controlled Supertooth 3 speakerphone (US$130).

The 3.8-ounce hands-free device is perfect for those of us who hate to read directions because it actually tells you how to use it in your choice of six languages.

The package includes not only the black speakerphone, but adapters for AC and car power. It took about a minute to connect with my phone, and I quickly figured out how to dial and answer calls by voice command. Its audio is clear and static-free, but a little hollow at times.

Supertooth 3 has a range of 40 feet and its battery lasted for four hours of use. The device easily clips to any car's visor, which means it's always there waiting for your next call.

Control the show: Interlink Electronics VP6600 ExpressCard Media Remote for Bluetooth

Interlink's US$50 VP6600 media remote weighs an ounce and is smaller than a business card, yet can control a PowerPoint show so well that every mobile presenter should pack it -- especially because it charges and travels right in your notebook's ExpressCard slot.

Setting up the tiny remote control with my notebook took a minute, but there's neither an on-off switch nor a light, so you have to trust that the VP6600 is working. On top of buttons that move your slides forward and back, and change the volume up and down, there's a handy mute button. The device, which requires Windows XP or Vista, can also play and move among tracks of a CD or DVD.

The VP660's 50-foot range can come in handy when presenting in a big room. The remote control card ran for more than three hours on a charge; after 30 minutes of idle time it puts itself to sleep. Let's hope that your next audience doesn't suffer a similar fate.

All audio, no wires: Yamaha NX-B02 Bluetooth Wireless Speaker

Yamaha's US$200 NX-B02 Bluetooth speaker set puts an end to the presenter's nightmare of fumbling with wires to connect speakers or -- worse yet -- not finding the right audio cable. A single box, which contains two speakers, connects in a flash, runs on batteries and sounds like a much larger speaker system.

At 1.5 pounds and about the size of a small clock radio, it's hard to believe that the NX-B02 contains a 10-watt amplifier. The unit's 1.75-in. Titanium cone speakers are augmented by two passive radiators (diaphragms that move in response to the main diaphragm's vibration, strengthening the bass). It comes with an AC adapter but not the four AA batteries that can power it for six and a half hours.

Connecting it to my phone and handheld was straightforward and took all of a minute each. The NX-B02's audio is surprisingly rich, on a par with a good boombox. It has a 20-foot range and can easily fill a room with wireless sound.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
