As anyone who’s spent time there knows all too well, the use of a cell phone while walking in midtown Manhattan is now mandatory. Or maybe not; but a casual observer could easily to make that inference. Ironically–and this part is true–it is illegal to use that same phone while driving a car on those same streets, at least when the phone is held in one hand, as it’s designed to be used. New York was the first state to outlaw hand-held cell phone use while driving, and it looks as though much of the rest of the country will follow that lead. Needless to say, this has been a windfall for manufacturers of hands-free kits.
You’ve probably seen such kits advertised on late-night TV, for 20 or 30 bucks. Maybe you’ve bought one. If not, don’t bother. Based on a random sampling of several kits in that price range, I can say with some certainty that they are uniformly awful. Using one will allow you to keep both hands on the wheel, but won’t be of much use if you want to carry on a conversation that isn’t punctuated by both of you saying “what?” every few seconds. Fortunately, excellent alternatives are available. I’m going to discuss three of them: a wired car kit, a Bluetooth car kit/speakerphone, and a Bluetooth earpiece.

In stark contrast to the typical lighter-socket assemblage, Unwired Technology’s $119.95 UC-500 Handsfree Kit is a stand-alone device that attaches to the vehicle’s headrest support. If the headrest is supported by a pair of tubes, the UC-500 snaps right into place. Other headrest configurations require some–but not much–ingenuity for installation. Once in place, the UC-500 positions a speaker to the driver’s left, and a microphone on the right. The microphone is mounted on a 16-inch gooseneck boom, allowing it to be positioned to the side of the driver’s head, out of the line of sight. A six-foot cord, with a standard 2.5mm plug, connects the UC-500 with most phones. (The unit comes with adapters for other phone types.) Power is provided by three AAA batteries that, thanks to auto on/off circuitry, are good for six months of normal use.
I plugged the UC-500 into an old non-Bluetooth Motorola v60 which, despite its age, supports voice-activated dialing, and made several test calls. The speaker sounded fine; it was, in fact, better than the one in the v60. However, the true test of a hands-free kit is how it sounds to the other party, and in this respect the UC-500 delivered stellar performance. Not one of our guinea pigs was aware that a hands-free kit was being used. In fact, the quality was so high that only a few could tell we were on a cell phone. Credit for this performance is due to mic/speaker isolation circuitry that eliminates feedback, and to a proprietary ambient noise reduction system. Normal conversation was possible even with windows open and the radio playing. In fact, the noise reduction system is effective enough to allow the UC-500 to be used in an open convertible.
While considerably more expensive than run-of-the-mill hands-free kits, the UC-500 is worth every penny of its price. It represents a quantum leap in performance and convenience over lesser devices.

If your phone is equipped with Bluetooth, and you don’t want to bother with a wire in the car, Motorola’s HF820 (recently discontinued but still readily available, and at a whopping discount off the $99.99 list) easily meets and exceeds The Grown-Up’s Guide’s performance and usability benchmarks. The HF820 can serve not only as a hands-free car kit but a desktop speakerphone for small-group conference calls. Motorola includes a lanyard with the HF820, so you can also wear it as a necklace, carry on hands-free conversations as you walk down the street, and look like a crazy person. (If you want to look like a crazy person who doesn’t wear a necklace, clip the HF820 to your belt. You’ll have to raise your voice a bit to be heard, which will only enhance the effect.)
The HF820′s pairing procedure is simple and quick. With the unit already on, you press and hold the volume/power button. Pairing mode is indicated by two beeps and a steadily lit LED, at which point you make the connection using the phone’s menu. The HF820 can store pairing data for up to eight phones, any of which can initiate a connection.
Motorola spread the HF820′s controls out across the chassis, so you’ll only hit the intended button. The power control is also the volume toggle, but switching the unit off requires that you hold the button in for a few seconds, so there’s no danger of doing so while adjusting the volume. The central multifunction button is used to initiate, answer, and end calls. If your phone supports enhanced functions like hold and three-way calling, the same button invokes them as well. The mute button is fitted with an LED reminder, and a 2.5mm jack accepts a wired headset for privacy.
When I initiated calls using the phone’s keypad, the HF820 performed like a champ, and the speaker delivered crisp, clean sound. My fellow conversationalists could tell that we weren’t on a “normal” phone, but didn’t complain about it. I did, however, have some intermittent trouble getting the Motorola E815 phone to recognize voice commands. In some cases, the phone would ask for confirmation (i.e., “did you say call so-and-so?) and when I said “No!” it took it for yes and made the call. A second sample didn’t exhibit this behavior, so I’ll chalk it up to a defective unit that somehow made it into the field. If yours has that problem, return it for another, and life will be good.

Truth be told, for personal use I’ve abandoned both the UC-500 and HF820, and now rely exclusively on a Bluetooth headset to keep me from running afoul of the law. After trying six highly-touted models, from as many manufacturers, I settled on Motorola’s HS850. The main reason I chose the HS850 is that I don’t like to stick things in my ear. Unlike most of the headsets I tried, the HS850′s speaker rests gently outside the ear canal, held in place by a rubbery loop that can be deployed for left- or right-ear use. Now, I don’t wear the HS850 unless I’m engaged in a conversation, but it’s comfy enough that I could do so without complaining. (And for all I know, you want to wear a Bluetooth headset every waking hour, just in case. This one, you could.)
Of course, while comfort is an important criterion when choosing a headset, it means little if the unit’s performance and usage-related ergonomics don’t measure up. From a performance standpoint, the HS850 is completely transparent. By this I mean simply that the sound quality (at both ends) is the same as that of the phone itself, and what more could you want? The headsets usability is stellar, especially as compared with some of the more fiddly alternatives. The microphone is on a hinged “boom” that’s shown in the deployed position in the photo. Flipping it into that position turns on the power and initiates a connection with the associated phone. (My phone is set to accept the connection automatically, so when a call comes in all I have to do is flip the HS850 into working mode, slip it on, and begin the conversation.) A single multi-function button controls call start and end, redial, hold, mute, and three-way calling, while a pair of smaller buttons raise and lower the speaker volume.
The HS850 is priced a fat one cent under a C-note, but you should be able to buy it for around forty bucks. If size is an issue, for the same list price you can also opt for the newer H700, which is roughly 30 percent smaller and comes in several colors. Being newer, it probably isn’t discounted as heavily.
