The Best Stereo Bluetooth Headsets

Do you use your phone for music and for making calls? A good stereo Bluetooth headset will help you get the most out of it. Here are the best models we've tested recently.




Sony Ericsson HBH-IS800



The main attraction of the Sony Ericsson HBH-IS800 headphones is their teensy size. Weighing less than half an ounce, these headphones rely on a slender strand of cable to connect the two earbuds. Such luxury and convenience don't come cheap, though: The headphones list for $200.
In general, the headphones delivered great-sounding tracks, with crisp vocals and warm (but not overwhelming) bass. Phone call quality was mostly good, too. Unfortunately, the headset's controls are minimal: You can use the action button to turn the headset on and off; to initiate, accept/reject, and end a call; and to play or pause tunes. But you can't use it adjust the volume or skip forward or backward through tracks.
If you're willing to sacrifice some phone and music controls for an ultrasmall headset with dependable audio quality--and the hefty price tag is no barrier--the Sony Ericsson package has got the goods.
For an in-depth examination of the new generation of wireless stereo headphones, see "Next-Generation Stereo Bluetooth Headsets." For a comparison chart of the five stereo Bluetooth headsets I reviewed, see "Stereo Bluetooth Headsets Offer a Range of Strengths and Weaknesses."




LG Electronics HBS-250


Earbuds are not everybody's choice. If you want to avoid inserting doodads in your ears, check out the $80 HBS-250 from LG Electronics. The headset consists of two ear muffs and an adjustable wire that connects them.
The HBS-250 headphones may not be stylish, but they're padded and comfortable. And the music experience was quite good, with great bass and warm tones overall. Phone conversations sounded fairly good, though voices sometimes sounded choppy.
Some of the headset's controls are small and hard to find by feel. I had to fumble around the top of the headset (or take it off and look at the thing) until I got a feel for where the buttons were located. Consider the HBS-250 if you want a headset whose earpieces to sit against your ears--not inside them--and deliver reasonably good audio quality.



Motorola MotoRokr S9-HD for iPod Wireless Stereo Headphones

If you're comfortable with a sturdy headband hovering above the back of your neck, then the $130 Motorola MotoRokr S9-HD headphones might tickle your fancy. I found them clunky to wear at the outset, due to the headband's relative stiffness.
Overall, my tunes sounded impressive over this headset. The S9-HD delivered a rich stereo experience, including great-sounding bass. Call quality was up and down, though. Most of the time, voices came across loud and clear to me; but on a few occasions, words became stuttered. Background noise proved very distracting, too.
After a couple of hours of wearing the S9-HD, my ears felt as though they were being dragged down. I also found that the S9-HD restricted my head movements somewhat, so it worked better for me when I sat at my computer than when I was buzzing around in the car or running.




Altec Lansing BackBeat 906


When I first donned the $130 Altec Lansing BackBeat 906 headphones, I couldn't get them to sit comfortably. The earbuds are attached to a wide ear hooks that come down over the top of your ears. The buds sport a beak-shaped eartip, which you use to anchor the headphones in your ear. These buds were too large for my ear canals--and unfortunately, the company does not provide other bud sizes.
Music sounded pretty good, though not as rich or as warm as it did over other headphones I tested. Phone calls sounded fine, and I was particularly impressed with how the BackBeat handled background noise. Callers could hear only faint traces of music emanating from my nearby stereo, for instance.
The BackBeat 906 bundles a Bluetooth adapter for the iPod and other MP3 players. If you want a set of headphones and an adapter to let you listen to your tunes on your iPod cord-free, the BackBeat is well worth considering.


Samsung SBH700



I was not a happy camper when I wore the Samsung SBH700 headphones ($100). I couldn't arrive at a comfortable fit. For starters, the earbuds were too big--the package does not provide alternative bud sizes--and the squarish hooks didn't sit properly over the curve of my ears. In addition, the SBH700's headband, which wraps around the back of the user's neck, felt heavy and imparted a sagging sensation. After wearing the headset for a while, my ears simply felt fatigued.
On the plus side, my tunes sounded good, with nice overall brightness and adequate bass. Phone conversations over the SBH700 came through loud and clear on my end. The parties on the receiving end said that they could hear me just fine, but that I sounded a tad muffled.
The red-and-silver unit looks stylish and sporty, but its good looks and satisfactory audio quality are outweighed by its subpar comfort and design.

New iPod Shuffle moves controls to headphone cord
Posted by Rob Beschizza








Available at 4GB, the fresh model is long, thin and sleek--somewhat like the original first-gen model, but with a clip. It's available in light gray and dark gray, and the controls are moved to a bulbous clicker on the cord.
My problem with this is going to be being stuck with Apple's headphones, or having to buy some fancy new officially licensed headphones that also have the new control block built-in. This isn't new, as far as little audio players go, but is still a shame: for today's show, the part of Sony will be played by Apple.
It also has a new feature called Voiceover: press it, and the Shuffle tells you what's playing.







They're up at the Apple Store for $80.
Update: Mute Kaiza points out that it might be easy to splice better headphones onto the control unit, so long as you're O.K. ruining your beautiful Appley lines.
As an aside, I imagine Belkin will announce an adapter within minutes. I still don't want to pay for one, even if it's just $10.
Great comment from reader Cyklo: "I'm amused that if you swap out the inline-control bundled earphones for your own, you reach Apple Zen: an iPod with zero buttons."

Next-gen iPod touch, iPhone to Support low-power 802.11n

Next-gen iPod touch, iPhone to support low-power 802.11n

By Prince McLean




Wireless radio component specifications contained within beta distributions of iPhone 3.0 firmware reveal support for a new chip enabling low power 802.11n that's bound for Apple's third-generation iPod touch. It's therefore also likely to be included with new iPhone models.

The version of the existing Broadcom chip that supplies WiFi and Bluetooth on existing models jumps from BCM4325 to BCM4329, according to resource files reserved for a third-generation iPod touch. The component upgrade adds new support for 802.11n features, including the ability to find and join 5GHz networks.

Existing iPhone and iPod touch models only support 5GHz 802.11a networks, or 2.4GHz 802.11b/g networks, forcing users who want the top speed of 802.11n (available on all MacBooks) but compatibility with 802.11b/g networks (to use the existing iPhone) to set up a 2.4GHz compatible network. That compromise forces the wireless network to deal with interference from other networks on the often crowded 2.4GHz band.

Apple's latest generation of AirPort base stations added new hardware support for dual-band networks, allowing both fast and slow devices to connect to independent 5GHz and 2.4GHz signals at the same time. However, this isn't possible with previous AirPort base station hardware, or when setting up an ad-hoc WiFi network from a notebook, for example.




















New support for 802.11n in the upcoming iPhone and iPod touch models would also provide the devices with additional network speed and reception range features of the significantly faster 802.11n specification, which are related to channel bonding (using two channels at once to double the top reception speed) and MIMO, the ability to use multiple transmit and receive antennas to improve reception speed and range.

Other features related to 802.11n include Space Time Block Coding (STBC), which sends the same data across multiple antennas for redundancy against radio interference; Short Guard Interval (SGI), which increases the data rate by squeezing out shorter padding intervals; A-MPDU, the aggregation of multiple MAC-level service data units; Block Ack, which increases efficiency by transmitting multiple data frames followed by only one acknowledgement frame in a transmission block; Greenfield mode, the increased efficiency gained by dropping 802.11a/b/g backward compatibility; and RIFS, reduced interframe spacing, which minimizes unused radio dead time by cutting the interval time between sent packets.

The new device also focuses on efficient power management, with a special integrated PMU (power management unit) and a shared Bluetooth and WiFi receive signal path, which "eliminates the need for an external power splitter while maintaining excellent sensitivity for both Bluetooth and WLAN."

The new component should dramatically speed up WiFi throughput and flexibility as AT&T and other UMTS mobile providers also upgrade their 3G networks to take advantage of parallel improvements in mobile 3G speed capacity expected in the new iPhone.

Top 10 Strangest MP3 Players


10. Teddy Bear MP3 Player



This makes our list because...well...it's a teddy bear shaped MP3 player! The keys look almost too tiny to press and it only comes with 128MB built-in memory.

Undeniably cute and expensively priced. Tomy's "Teddy Bear MP3 Player" boasts just 128MB memory and only supports MP3/WMA audio playback.

FEW OF MP3 YOU LOOKING FOR


Sony
:


Sony – a name well known in the consumer electronics world. At CES 2005 they announced the forthcoming arrival of their NW-HD3 model with an estimated price of $350. Sony previously has been hampered somewhat by their sticking to digital audio players which only provide native support their ATRAC3 format. This sound type, while superior to MP3, has not caught on much. Sony hopes to change their market share by introducing players, like the NW-HD3, which offer native support for MP3 as well.

The NW-HD3 20 GB model will come in five different colors and has quite a sophisticated, urban look. It will support USB 2.0 high speed file transfers, offers shock protection and skip free technology and has a large toggle navigation button on the front of the player which will navigate functions on the seven line backlit LCD. The LCD’s light, incidentally, will coordinate with the body color of the player.

Sony also mentioned the NW-HD3 will get an estimated 30 hours of playback time between charges of its internal battery.


Lexar:


Lexar, a maker of flash memory cards like Sandisk, used CES 2005 to show off some new models in their flash memory player line. The LDP-800 (256 MB version: $159, 512 MB version: $199) and LDP-200 (0 GB: $39.99, 256 MB: $89.99, 512 MB: $109.99 and 1 GB: $149.99) will be available in March and February respectively.

The LDP-800 flash model will, among other features, provide virtual surround sound and support OGG, WMA and MP3 music files. It will also provide both line out and line in capabilities for music playback and recording, broadcast over a built in FM transmitter and provide the ability for memory expansion through an internal SD card slot.

Lexar’s economic focused LDP-200, by contrast, will offer no internal memory what so ever. Music will need to be stored on a SD card (three options of the LDP-200 will include cards in the packaging) and inserted into the player’s dedicated card slot to be heard.


Rio:


Rio is another one of those names, like Creative, which has been a player in the MP3 player market for years. Their latest offering, the ce2100, promises to keep things interesting and allow Rio to remain as one of the leading companies.

The ce2100, expected to ship in the first quarter of this year with a price tag of $199, will offer up a 2.5 GB hard drive which can play MP3 and WMA files. The player’s body will sport an ultra slim, tapered design and be capable of playing for up to 20 hours.

Rio also announced at CES they would be adding a pearl color to their highly popular Rio Carbon 5 GB player.




iRiver:


Is it possible digital audio player company iRiver might ever find themselves up the river? With announcements of new cutting edge players like the H10, it is highly unlikely.

The H10, when it hits stores this month for $279, will unveil itself as a cool looking 5 GB player in four colors. Besides supporting MP3 and WMA music files, the H10 will double as a photo viewer capable of showing off JPEG images on its color screen. iRiver’s newest entry will have plenty of playtime, being capable of going for up to 12 hours between charges.

Other noteworthy things about the H10 include the rechargeable battery being removable and replaceable, virtual surround sound support, an integrated voice recorder and integrated FM tuner/recorder.


RCA:


RCA’s Lyra line of digital audio players was given a boost this year at CES. Three new models, including one with photo viewing capabilities, are set to be on sale soon.

The Lyra Micro Jukebox RD2765 (April release date for $269) sports a 5 GB hard drive and 1.5” color screen which allows for the viewing of JPEG images and CD cover art. The player is fairly compact, being not much bigger than two packs of gum, and can store and play MP3 and WMA music files. It uses a jog wheel for navigation and selection.

In the realm of straight digital audio players, RCA’s newest entries are the RD2212 (April for $129) and RD2312 (May for $129). Both 256 MB flash memory players are geared towards the more active crowd. The former sports a number of useful features for athletes, including stopwatch, calorie counter and heart rate monitor, in its splash proof body.

The RD2312, meanwhile, has a “high tech form factor” and is designed to fit specifically into the palm of your hand. It sports an amber colored backlight, dual orientation LCD display which inverts when the player is turned upside down and an estimated 20 hour battery life.
