Reaching for the Height of Radio

Katherine Boehret — Tue, 26 Jan 2010 22:21:11 +0000

Despite the popularity of music downloads or streamed music through online services like Pandora, the good old radio is still a source of entertainment for many people. It turns on as soon as the car starts and inspires shower singers every morning. Plus, it works pretty much the same as it has for decades.

The trusty radio has finally received an upgrade—to the world of high definition. HD Radio, which has been gathering steam for a few years, sounds better and offers more channels than traditional radio. It also sends properly equipped devices text data like a song’s title and artist name as well as traffic, weather and stock information. One HD Radio even lets you pause programming in mid-stream, so you don’t have to miss a song or NPR story just because you’re drying your hair. And future HD Radio devices will record programming like television DVRs do now.

The Sony (above) and Coby Electronics (below) devices use HD Radio technology to play more stations at better sound quality.

This week, I tested three HD Radio devices to see what all the hype was about: Best Buy’s Insignia $50 HD Radio Portable Player (http://bit.ly/75FcIc); Coby Electronics Corp.’s $100 Portable HD Radio System (http://bit.ly/6G6g4Q); and Sony’s $160 HD Radio with Dock for iPod + iPhone (http://bit.ly/8c0Bqf). I also talked with iBiquity Digital Corp., the company that developed HD Radio technology and licenses it to broadcasters and radio manufacturers, about how this works.

I found some worthwhile offerings in HD Radio, like commercial-free, sub-channels within existing stations and better sound quality. IBiquity claims that HD Radio makes FM stations sound like CD quality and AM stations sound like FM; to my ear, this seemed to be true.

Overall, I didn’t hear enough incredibly great content or sound quality to want to run out and replace my old radios. Washington, D.C., where I live, supposedly offers 41 HD Radio channels, but I couldn’t find as many as that. Over 2,000 primary HD Radio stations and some 1,100 sub-channels can be heard in all 50 states and Puerto Rico, but some areas won’t offer as many stations, according to iBiquity.

Tuning in each HD station takes longer, like the way changing channels on a digital TV takes an extra second. But in my tests, this process took five seconds or more per change of channel. This kind of delay is enough to try anyone’s patience.

It might help to explain the technology behind HD Radio. HD Radio makes it possible for local broadcasters to transmit content via digital signals on existing AM and FM frequencies. The digital signals are encrypted and eliminate static heard in analog broadcasts, resulting in better sound quality. But they take longer to be decoded by HD Radio receivers.

Many people mistakenly think that in order to listen to HD Radio, they must pay an extra monthly fee like with satellite radio. If you buy an HD Radio device, you’ll only pay for it because the service itself is free; its price is built into the cost of the hardware.

Besides boosting the signal, HD Radio offers extra channels of programming you wouldn’t hear on a regular set. It allows existing FM channels to play additional content on “multicast” channels. Most multicast channels are commercial-free, and they appear on the radio’s display as HD2 and HD3.

Don’t confuse HD Radio with the text data that scrolls across the screens of many current radios, like my car radio. This is a non-audio service called Radio Broadcast Data System that has been around for a while.

Each of the radios I tested offered an HD Seek feature—a way of skimming through all stations to find and play those that could be heard in HD. But HD Seek didn’t stop on multicast channels; to get to those on each radio, I had to press buttons to tune up or down while listeningwhile already listening to to a main HD radio channel. Some HD Radio models have HD Seek tuning functions that find HD1 stations as well as HD2 and HD3 channels. I saved these HD2 and HD3 multicast channels in my radio presets so they were easier to find again.

While a radio was tuning in, or linking into, a channel (the process that took several seconds), an “HD” logo flashed on each radio’s display. This logo turned solid when the station was found and finally started playing. I listened to multicast channels like a bluegrass/country station from my local NPR channel. Another station’s two multicast channels played “South Asian” music and the Mormon Channel.

As its name suggests, Sony’s HD Radio with Dock for iPod + iPhone has a built-in dock for iPods, iPhones and iPod Touches. If, while using this radio, you hear a song on an HD channel that you like, you can hit a “Tag” button to save information about that song. The next time you dock an iPod, iPhone or iPod Touch into the Sony radio, these tags are transferred onto the portable player. When you plug that device into a computer and open the iTunes Store, a list of the tagged songs appears, making it easier to recall songs you liked and may want to buy. This radio is a tabletop model and has the largest display screen of the three radios I tested. It also comes with a remote. It saves up to 20 FM and 20 AM presets.

The Insignia HD Radio Portable Player is a much smaller unit that comes with earbuds and an armband for exercising. If this radio tuned in an HD channel that offered multicast sub-channels, these were indicated on the display with a “+” sign, like “HD1+.” The Insignia radio stores 10 preset stations.

The Coby Electronics Portable HD Radio System resembled a single, lightweight speaker with a wheel, six buttons and a digital display on it. IBiquity Digital said this model uses an older HD Radio technology that doesn’t offer as much reception sensitivity as the Sony and Insignia. Still, it was simple to use, and its wheel made it a cinch to tune in HD2 and HD3 channels. It stores up to 10 presets.

In September, when Microsoft’s Zune HD was released, I tested its built-in HD Radio, the only such device capable of pausing live radio content. I paused music and talk radio on the Zune’s HD Radio when my phone rang, then un-paused the station to resume. This doesn’t work if the device is turned off and on again before resuming play.

Along with stand-alone radios, HD Radio receivers also are becoming more common in home audio systems and in cars. But while HD Radio’s sound quality and extra channels are definite pluses, the number of available stations needs to improve to make the wait for the HD channels to start playing more tolerable.

Bluetooth Headsets That Up the Chic Factor

Katherine Boehret — Wed, 02 Sep 2009 01:08:04 +0000

The cover of Wired magazine’s August issue showed Brad Pitt wearing a Bluetooth headset with the words, “Ditch the headset. He can barely pull it off—and you are not him.”

[ See post to watch video ]

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.

Aliph’s Jawbone Prime

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.

The Plantronics Discovery 975

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.

How BlackBerry Models Differ

Walter S. Mossberg — Wed, 18 Mar 2009 23:12:02 +0000

Here are a few questions I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability.

I get confused by all the different models of the BlackBerry — Bold, Storm, Curve, Pearl and so on. Can you briefly explain the differences?

There are too many models to list here, because RIM, the maker of BlackBerry, makes varying versions for competing wireless carriers, and these may have different features, even if they look the same. However, here’s a quick breakdown of the main flavors.

The Bold is the top-of-the-line BlackBerry, relatively large and costly, with a wide keyboard and a big, vivid screen. The Curve is its little brother — still sporting a good, full, keyboard, but lower-priced, smaller and lighter. The newest Curve, called the 8900, has a beautiful screen and is even sleeker than its predecessor.

The Pearl is a slimmer, low-priced, more fashion-oriented model with a truncated keyboard that has two letters on each key and relies on software to guess which one you meant to hit. The Pearl Flip is much like the Pearl, except, as its name implies, it’s a flip phone.

The Storm is the BlackBerry line’s most direct competitor to the Apple iPhone. It’s the only BlackBerry without a physical keyboard, instead relying on a large, beautiful touch screen for typing and navigation. Unlike on the iPhone, however, the Storm provides physical feedback each time you press down on the screen.

I’d be interested in the new, tiny iPod Shuffle, except that I dislike Apple’s earbuds. And, because they have now moved the playback controls to the earbud cord, I can’t use my favorite third-party set. What are my options?

Well, one option is to buy the old model of the Shuffle, which Apple is keeping on the market. It’s larger, but still very small, and has the controls on the player itself, rather than on the earbud cord, so you can use plain old earbuds or headphones from other companies. Plus, at $49, it’s $30 less, though it has only 25% of the capacity of the new one and lacks the new model’s voice features.

Another, costlier, option is to buy better earbuds that have the new controller built in. Apple sells a pair of $79 in-ear buds with a control module on the cord. They were designed for the iPod Touch, but the company says they work perfectly with the new Shuffle. Several other headphone companies, such as Klipsch, have announced plans to offer either headphones or adapters with Shuffle-compatible controls in coming months.

Is it safe to upgrade my Vista PC to the beta version of Windows 7?

Since it is a beta version, there is always some danger of problems. But I have upgraded a couple of Vista computers with no special tricks or help, and with no significant problems. Still, there are a couple of caveats. First, Microsoft will be replacing the beta with a more polished “release candidate” that could involve a re-installation process, so you may want to hold off. Second, Microsoft isn’t guaranteeing that every hardware feature on every computer or peripheral will work properly under the pre-release versions.

The Littlest iPod Packs In Songs and Finds Its Voice

Walter S. Mossberg — Thu, 12 Mar 2009 01:02:05 +0000

In these days of economic distress, it’s nice when technology companies add innovative features to the products at the bottom of their price ranges. So it’s notable that Apple’s cheapest iPod, the oft-forgotten Shuffle model, is getting smarter.

In fact, the latest iPod Shuffle, announced Wednesday and available now for $79, is the first portable music player I’ve tested that announces what’s playing. Push a button and it will tell you, in a computerized voice, the title and artist of whatever song you’re hearing. Keep holding that button and it will recite a roll call of all your playlists, allowing you to select among them. In my tests, this worked as advertised.

[ See post to watch video ]

In addition, this new Shuffle is almost impossibly small. The company has moved the playback and volume controls off the device and onto a small, convenient module built into one of the earbud cords. That allowed Apple (AAPL) to severely shrink the player itself, which, like the two Shuffle models before it, lacks a screen. Apple claims it’s the world’s smallest music player, smaller than a AA battery or a house key.

The result is an iPod that contains four gigabytes of memory and holds 1,000 songs — twice the capacity of its $69 predecessor — yet is just a little blank rectangle of aluminum, available in silver or black. It’s a mere 1.8″ long, 0.7″ wide, and 0.3 inch thick — including a stainless-steel clip that’s built into the back for attaching it to clothing or backpacks.

This player is so small and thin that it reminds me of the popular “Saturday Night Live” skit in which an actor playing Apple CEO Steve Jobs shows off a series of tinier and tinier iPods culminating in a final fictional model that’s invisible. I actually dropped the new Shuffle while testing it and it took a couple of minutes to locate it behind a table leg.

After using this new iPod Shuffle for a few days, I can say that I like it. It does a good job at playing back music, podcasts and audio books. I found the speech function intelligible and helpful, and the earbud-mounted controls convenient and easy to master. And its tiny size and weight of about a third of an ounce make it an especially good choice for people who use their iPods while exercising.

Apple’s new iPod Shuffle

Only a single button appears on the iPod itself, as opposed to on the earbuds. It’s a sliding power button on the top edge that has three positions — one for “off,” one for shuffling your music, and one for playing your songs in order. Once you set this button, you never have to touch the iPod itself, until you want to turn it off.

The new speech-based navigation feature allows the Shuffle, for the first time, to handle multiple playlists, just like on the larger iPods.

In my tests, I managed to squeeze in more than the 1,000 songs Apple claims. I filled my test Shuffle with nearly 1,100 songs, plus a half dozen podcasts and an abridged audio-book edition of President Obama’s “The Audacity of Hope,” read by the author. My music was organized into about 15 playlists, and I was able to switch among them easily using the voice system.

To pause or resume a song, you click the large center portion of the earbud controller once, quickly. To skip to the next song, you click the same button twice, quickly. To change to the previous song, you click it three times quickly.

If you want the computerized “announcer” to identify the song, you press the center button for a longer time, and you keep holding it to start the playlist roll call. When you hear a playlist you want, you press the button again. Smaller buttons at the top and bottom of this earbud controller adjust the volume up and down. It sounds more complicated than it is. While the voice function is in use, the music keeps playing in the background, at reduced volume.

The computerized voice, available in multiple languages, is hardly perfect. Like all such computer voices, its cadence can sound robotic, and it clips some syllables, but I found it perfectly understandable.

The spoken names of your particular songs, artists and playlists are added when you sync the Shuffle with iTunes. The voice quality is best when using a Mac with the latest operating system. It is slightly cruder on Windows or older Mac operating systems.

Even on the latest Macs, the voice got some words wrong. For a live concert album, it pronounced the word “live” as “liv,” and in another case, it pronounced the Roman numeral “IV” as “eye-vee.”

There are some other downsides. The claimed battery life is just 10 hours, down from 12 on the prior Shuffle model. You can’t fully operate the Shuffle with regular earbuds or headphones that lack the special controller. And, if you have numerous playlists, it could be tedious waiting for the voice control to say all their names until it reaches the one you want.

Still, Apple has packed a lot of new intelligence into a truly tiny music player, at a pretty low price.

Phone Headset Curbs Sounds of the City

Katherine Boehret — Tue, 07 Oct 2008 23:30:02 +0000

Wireless headsets can be a real boon to mobile-phone users, especially for chatty folks who often have their hands full. 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.

Getting a New Windows Computer With XP

Walter S. Mossberg — Thu, 14 Aug 2008 00:00:45 +0000

Here are a few questions I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability.

I am in the market for a new Windows computer, but I prefer the Windows XP operating system, not Vista. I understand Microsoft has now barred the major PC vendors from selling XP systems. Is there a way I can get around this?

If you want a new, brand-name PC that comes pre-loaded with the seven-year-old Windows XP operating system, you can still get one through an odd and circuitous process. Most major PC makers will sell you selected Vista models with an option, which sometimes costs extra, officially called a “downgrade,” but sometimes marketed as an “upgrade” or “bonus.” You may have to hunt through the selections offered by the computer makers to find one that has this XP option.

When you order a PC in this fashion, you are technically buying a Vista machine, and Microsoft counts it as a Vista sale. But the computer company actually loads XP on the new hardware, in place of Vista, before it leaves the factory. In many cases, you also get discs containing Vista, in the event you wish to switch to the newer Vista operating system later.

I was wondering if you could give me some suggestions of a small, light portable radio-type gadget with earbuds that would be good for me while I do athletic activities like riding my bike. I want something that will give me different pre-programmed selections of music, not something that I have to load with music (I don’t remember names of songs). I love my Sirius satellite radio in my car.

My first reaction is to suggest you simply get the portable, small, personal Sirius radio that is meant for carrying on your person. It’s called the Stiletto 2 and costs around $300. Like the one in your car, it does require a subscription, but it is much smaller. I haven’t tested it, but you can get more information at sirius.com.

However, this unit isn’t in the smallest class of portable music players, so another alternative might be to get a very small portable player, which, while it allows you to download music, also has a built-in FM radio. Among these is the smallest Microsoft Zune, called the Zune 4 GB, at about $100, and the Sansa Clip, starting at about $35. Neither requires a subscription fee. Information is at zune.com and sansa.com.

The popular Rhapsody subscription music service is also available on portable players, and offers pre-programmed channels of music. Some of these players also include FM radios. Information on these is at learn.rhapsody.com/devices.

Last week, you said you didn’t know of a dedicated gadget that simply allows people to both send and receive emails. What about the MailBug?

Thanks for reminding me. The MailBug, which I haven’t tested, is a small, text-only terminal for sending and receiving email over a dial-up connection. It costs about $125 and requires a companion email service that is about $100 a year. It’s made by a company called Landel and can be ordered at mailbug.com.

While the device itself can’t send or receive photos or other nontext attachments, account holders with access to a computer can view such attachments via a Web-based version of their email accounts.
