Fashionable or not, more people are wearing these wireless headsets for making phone calls in the car and in everyday life. This week, I reviewed two that look stylish enough that you won’t mind being seen wearing them: Plantronics Inc.’s Discovery 975 (Plantronics.com) and Aliph’s Jawbone Prime (Jawbone.com).

These Bluetooth headsets cost $130 each and use the best technology from their respective companies, including impressive-sounding features like AudioIQ 2, WindSmart, NoiseAssassin 2.0 and an Acoustic Voice Activity Detector. Each headset aims to deliver clearer incoming and outgoing sound.

After using these two headsets in an office, while walking through noisy city streets and as I drove a car with its windows open, I found that I liked the Plantronics Discovery 975 more than the Jawbone Prime. It felt more comfortable and stable in my ear, and its longer boom fit my face better than the Jawbone Prime’s stubby build. I was able to hear people more clearly while using the Plantronics (PLT) earpiece. But on the other end of the call, friends said the Jawbone Prime did a better job of muffling noise.

The Plantronics Discovery 975 also has something that the Jawbone Prime doesn’t have: a carrying case that holds the earpiece and charges it on the go. This charging case can triple the device’s talk time from five to 15 hours, and it holds its charge for a week on standby. A display on the case shows how much battery remains both in the charged case and on the earpiece itself when it’s held in the case.

I liked using this case because it meant I didn’t have to think so often about charging my headset. It also gave me a place to keep the small Discovery 975 earpiece, making it harder to lose in the bottom of a purse or large work bag. Though people who don’t carry briefcases or purses wouldn’t likely use this case, it’s convenient to have the option.

None of the Jawbone models come with carrying cases, though stores like Best Buy sell some cases that will hold Jawbone headsets. In the future, Aliph says it plans to make its own cases that will hold and charge its Jawbone headsets.

Aliph’s Jawbone has always been one of the most stylish Bluetooth headsets, thanks to its compact form factor and disguised buttons. The Jawbone Prime follows suit with a design that makes it appear slightly smaller than its predecessor. It comes in seven colors, including four especially bright “EarCandy” hues: Drop Me a Lime, Lilac You Mean It, ‘Yello! and Frankly Scarlet. The Prime maintains the original Jawbone’s namesake design feature: If worn properly, it touches your face near your jawbone and removes background noise. But a new feature also uses sound to detect the speaker’s voice and eliminate extraneous noise, so the headset doesn’t always need to touch the face.

The design of the Plantronics Discovery 975 ups the company’s chic factor by replacing its former model’s triangular boom with an elegant boom made of a single thin metallic sliver. It reminded me more of jewelry than a tech gadget. Like the Jawbone models, it looks less geeky because buttons are disguised, and it doesn’t emit a blinking blue light while in use—an improvement for Plantronics. The Discovery 975 comes only in graphite, though AT&T (T) stores will carry it in silver.

I started testing the Plantronics Discovery 975 and Jawbone Prime from my quiet office, without any distracting background noise. There, the Plantronics headset sounded better than the Jawbone, making my voice sound crisper, according to the person on the other end of line; likewise, his voice sounded louder to me. He also said he couldn’t tell I was using a headset while I was on the Discovery 975, but definitely knew I was on a headset while I used the Jawbone Prime.

Next, I walked along the streets of busy downtown Washington, D.C., chatting on each headset while standing steps away from the squeaky sound of car brakes and taxis honking. Here, the Jawbone did a better job of fading that street noise into the background, compared to the Plantronics headset.

I also took turns using the Jawbone Prime and Plantronics Discovery 975 while driving through the city with all four car windows open to test the antiwind capabilities of each. Here again, the Jawbone Prime sounded better to the person on the other end, though the Plantronics didn’t sound bad. My friend said it would have been impossible to guess where I was while making the phone call using the Jawbone Prime. But from my end of the call, I was able to hear slightly better while using the Plantronics Discover 975.

While using the Jawbone, I accidentally hung up on friends in midconversation a few different times because the place where I pressed to secure the earpiece in my ear was also the Talk button. I tried each of the Jawbone Prime’s three fit earbuds, three round earbuds and its included earloop, but none of these felt as comfortable as the Plantronics headset.

Both headsets are capable of using Multipoint technology, allowing them to connect to two Bluetooth devices at once. They’re each lightweight at .28 ounce and .35 ounce for the Plantronics and Jawbone, respectively; the Plantronics case weighs 1.27 ounces. According to each company, the Plantronics headset takes one-and-a-half hours to fully charge and lasts for five hours of talk time; the Jawbone takes 50 minutes to fully charge and lasts four and a half hours of talk time.

When both headsets were in front of me and I wanted to make a hands-free call, I reached for the Plantronics Discovery 975 because of its overall fit and feel in my ear. It stayed in place using a soft, gel insert that wasn’t uncomfortable, even after long conversations. Its sound quality was good enough for me.

In recent years, these headsets have bolstered their noise-canceling technology, making it easier to conduct conversations even while walking on noisy city streets.

Today, Motorola (MOT) is unveiling its $100 Motopure H15 Universal Bluetooth Headset. It’s available from Verizon’s (VZ) stores and Web site, and I’ve been testing it.

While focusing on the new Motopure H15, I also took another look at two noise-canceling headsets we reviewed in May — the $130 Jawbone from Aliph Inc. and the $120 Plantronics (PLT) Discovery 925. I made calls on the three headsets while standing beside a construction crew’s loud generator in busy downtown Washington, D.C., and, in a separate test, running my hairdryer on high in the background.

In both of these loud scenarios, the results favored the Motopure over the Jawbone and Plantronics Discovery. Of the three, the Plantronics headset allowed the most background noise through and made it difficult for people to hear my voice. The Jawbone was much better than the Plantronics headset, but not as good as the Motopure, which dimmed loud background noise to a faint hum and seemed to amp up the volume of my own voice. I called various people and even left myself voicemails so I could hear the differences.

More Microphones

The Motopure H15 uses two microphones, while the Jawbone uses two microphones and one modified microphone that works as a voice-activity sensor. The Plantronics headset uses one microphone. Motorola says one of its microphones hears the user’s voice, the other picks up background noise and a technology called CrystalTalk works to filter that noise out.

In my Motopure testing, I saw at work technology that Motorola says is meant to automatically adjust the headset volume as noises increase or decrease in the background. And at no point during my tests with the headset did friends on the other end of the line notice any odd echoing or fading volume in my voice, as with some headsets.

Snug Fit

Unlike the Jawbone, which — as its name reflects — works by touching bones in the face to eliminate excess noise, the Motopure H15 never touches one’s face. In fact, Motorola cites this as an advantage over the Jawbone because it doesn’t need to touch a user’s face to work. Motorola’s headset fits using a loop of clear plastic that wraps snuggly around the ear, along with an in-ear piece, though it took me a little while to figure out which of its five earbuds fit best.

And unlike the Plantronics headset, which has a larger, triangular-shaped boom, the Motopure has a tiny boom that folds away when not in use. Users receive calls by simply folding the boom down, which instantly turns the headset on and connects to calls. When the boom is closed, the headset turns off to save battery. I liked the finality of closing the boom and knowing my headset was definitely off whenever I put it in my purse. And in its tucked-in position, the Motopure H15 is petite and portable.

But if you’re wearing this headset on your ear, opening and closing the boom is almost impossible. Motorola recommends using the boom as you would a clamshell cellphone: Answer calls by opening the boom before donning the earpiece and end calls by removing the earpiece and closing the boom.

Of course, many users will want to keep the device in their ear for an extended period, rather than fishing for it when a call comes in. For them, the awkwardness of the boom switch may be a problem. They can still keep the Motopure on with the boom opened, receiving and ending calls at any time by simply pressing the large Call button. In this state, the handset is in standby mode rather than off — the same as most Bluetooth headsets waiting for calls.

One Headset, Two Phones

A plus of the Motopure is its ability to simultaneously pair with two phones, such as a personal cellphone and a work smartphone. Incoming calls to both lines are represented by different colored lights on the headset. But as soon as a call with one phone begins, the Bluetooth link to the second phone is disconnected.

The Plantronics headset also has dual-phone pairing capability, but the Jawbone doesn’t.

According to Motorola, the Motopure’s battery lasts for about 4.5 hours of talk time. The Jawbone’s battery lasts four hours; the Plantronics headset, five hours. In standby, Motopure and the Plantronics Discovery last for about seven days; Jawbone lasts for eight. Pressing and holding the Motopure’s up and down volume buttons spurs an indicator light to glow red, yellow or green to represent battery strength.

I liked the Motopure’s sturdy charging stand, which doubles as a holder for the headset. Though this desktop charger isn’t available today from Verizon, it will be available later this month from other carriers and retailers in a $130 bundle with the headset.

More Colors Later

Today, the Motopure is available in a slate color, but it will be available in black later this month and other colors are tentatively planned for November. The Jawbone and the Plantronics headset are each available in three colors, and Jawbone will release blue and pink headsets later this month.

Overall, the Motopure H15’s noise cancellation worked the best out of these three headsets, and its tiny build and fold-up boom make it a helpful tool for consumers who want quiet conversations no matter where they are.
