• Windsmart Technology allows you to seamlessly switch between two Bluetooth® devices
• Up to 6 hours talk time and up to 100 hours standby time
• Compatible with Bluetooth devices supporting the headset or hands-free profile

With Multipoint technology you can switch between your voice-enabled Bluetooth mobile phone, PDA or laptop. The headset's "smart" technology knows which device you are using and allows you to take calls from any device at the touch of a button. With the optional Plantronics Bluetooth Deskphone Adapter you can even switch between your office phone and your Bluetooth mobile phone. You'll never need to use a dedicated "landline" phone headset again.

The 510 features a noise-canceling microphone for clearer conversations, and it folds for easy storage. The boom also swivels for perfect positioning on either ear. One-touch call control buttons are placed for easy access, and you can easily redial the last number dialed and initiate voice-activated calls from the headset. Because the 510 is Bluetooth-enabled (it supports the Bluetooth 1.2 specification) you can roam up to 33 feet from your Bluetooth device. Meanwhile, the 510 supports adaptive frequency hopping (AFH) which helps avoid interference from wi-fi networks. Ample talk time is provided by the built-in rechargeable battery; you'll get up to 6 hours talk time and up to 100 hours of standby time.

• Can be worn on either ear; includes four earloops and five earbuds for custom fit

Sophisticated modern industrial style meets the next step in audio technology with the Jawbone Bluetooth headset.

It can be worn on either ear, and you can customize your fit by choosing from one of the included earloops and earbuds.

The first thing you notice about this headset is its rather chunky size and cheese grater-like texturing on the exterior. Designed by Yves Behar, an award-winning industrial designer who also contributed to the design of the OLPC (One Laptop Per Child, aka the $100 Laptop), the Jawbone certainly has that iconic modern look that will be copied for years to come. It's also a bit large on the face (due to the embedded technology and speech sensor), which reminded us of Lando Calrissian's assistant, Lobot. But then there's no easy way to disguise a Bluetooth headset, and it's probably an advantage as passersby won't think you're just muttering crazily to yourself.

The Jawbone can be worn on either ear, and it comes with four earloops of varying sizes to fit your lobe. Made of solid metal with a rubber cover, they're fairly comfortable around the ear. The trick, however, is getting it on over the ear, and this is the Jawbone's biggest disappointment. Because it's so stiff, you literally have to use both hands to try to slip it on over your ear. And since we don't wear our headset constantly, we missed a few calls while performing this dance. Also, the metal frame does bend (as we found after carrying it in our pocket), which can be viewed as an annoyance or as a feature--enabling you to form-fit the frame to your ear. It also comes with five ear pads of varying shapes and sizes, and we tried one of the teardrop shaped pads to secure the Jawbone inside our ear sans metal frame--it was comfortable and worked for awhile, but isn't a solution if you're moving around a lot.

As with Steve Jobs, Behar is not a fan of protruding buttons. Thus, the Jawbone's two controls are hidden within the headset, requiring you to press either the front or back of the unit to answer calls, adjust volume, or turn on/off the noise cancellation function. While we've read some reviews that complained about these hidden controls, we had no problem in accessing them and appreciated their tactile response. The Jawbone also comes with a custom-fit recharging cable that can either plug into a PC's USB port or into the included wall jack. We enjoyed the flexibility of the USB charging, but wished the cable could have been a more standard USB mini-jack (for those times when you forget to bring the cable along).

But the true test of the Jawbone is how its "noise shield" performed. First, a little about this technology. The Jawbone has a small piece of rubbery plastic that protrudes from the bulbous microphone and sits flush against your face, and this sensor tells the Jawbone whether or not you're speaking and can remove background noise from your ongoing speech signal. It can also dynamically adjust the volume of the incoming audio from your call.

We tried the Jawbone in a number of different situations, and for the most part it worked flawlessly. Sitting at our desk with the stereo volume cranked up while playing The Chemical Brothers, our call partner was none the wiser. She didn't hear any of the music coming through, and our voice came through strong on her end. While standing on a street corner, the undulations of traffic noise never made it through to our caller, while we noticed an uptick in volume with an increase in traffic noise.

However, the Jawbone wasn't perfect, as it doesn't do a great job in windy situations. Still, for the good majority of situations you'll find yourself in--from busy airports to talk-heavy coffeehouses to traffic-laden city streets--the Jawbone should perform very well, masking the surroundings to improve fidelity for you call partner as well adapting your ear volume to the surrounding environment. We just wish the ear frame was a bit more flexible.

Pros:

• Amazing background noise masking capabilities--even when faced with loud, thumping music
• Outstanding adaptive volume as the environment around you changes
• Options for customizing the fit

• Metal earloop frames are hard to quickly put on
• Non-standard USB connection is a bummer if you forget the cable at home

• Bluetooth wireless technology means that the sheer convenience of hands-free communication is enhanced with total freedom of movement.
• This universal accessory encourages users to update, change and evolve because it is compatible with all other 1.1 compliant Bluetooth wireless technology phones by Motorola and other manufacturers.
• Increased talk time of up to 8 hours and standby time of up to 200 hours.

The Motorola HS850 is the company's update to their HS810 headset, one of my personal favorites. The changes made to produce the new HS850 are few, but the effect is relatively substantial. But first, let's start with what is the same.

Like the HS810, the HS850 makes use of a body design that employs a folding microphone boom. The folding microphone boom acts as the on and off switch, as well as just providing a convenient way to make the headset smaller and more pocketable when not in use. When a call comes into your phone, you can turn on and answer the phone at the same time just by unfolding the microphone boom. You can end the call and turn it off by removing the headset and re-folding it. Using the headset in this way conserves battery power, since no battery juice is wasted on standby time - time where the headset sits around waiting to be contacted by a mobile phone or other compatible device. The physical design of the HS850 and the battery savings it imparts is my favorite aspect of the Motorola HS850.

Of course you don't have to remove and turn off the headset between calls. If the headset is already on when an inbound call comes, you will hear the ringing come through on the headset and can answer it by pressing on the main multi-function call control button. You can end the call with this same button, and adjust volume levels with the two volume buttons. If you are using a phone that supports the Hands Free Bluetooth profile, then you can also use the call control button to reject an inbound call or redial the last number.

The HS850's audio properties are also like those of the HS810 before it. The audio quality in both directions is very clear and understandable, but sounds a bit thin. You and the party on the other end of the call will both be able to understand each other easily, it just doesn't sound as full and natural as it might with some other headsets. The HS850 makes up for this small lacking by having great resistance to wind noise, though. That makes the headset perfect for people that enjoy driving with their windows down, or those that work outside. Most headsets are very susceptible to wind noise, the HS850 bucks that trend.

And now for the new stuff. First up, a more powerful battery. The HS850 I tested managed an amazing 7 hours and 50 minutes of talk time. That is a full two thirds improvement over the older model. The truly amazing part is that this new battery life didn't come at the expense of added weight. Like the HS810 before it, the HS850 weighs only .7oz (19.9g).

The next major change perhaps sounds more important than it worked out to be in reality. The HS850 supports the newer Bluetooth v1.2 spec, whereas most headsets support v1.1 only. Motorola claims that when used with a v1.2 compatible phone (there are still relatively few available at the time I write this), the HS850 will be able to connect faster, use less battery power, and offer improved audio quality. While I can see what appears to be a slight improvement in connection speed, I haven't really noticed much of a change in battery life or audio quality.

The last major change is purely cosmetic. The new HS850 headset is blue-gray in color, like a darker version of the HS810's color. I find it more attractive than the light silver found on the HS810.

But regardless of the color, you can't go wrong with Motorola's HS850, which I consider to be perhaps the best value on the market.
