Here's what you get when a manufacturer tries to justify a $199 price tag on its newest headsets. The Jabra Go 6400 (pictured above) and Pro 9400 look to be standard noise-cancelling Bluetooth and DECT headsets, respectively, with a multifunction button to answer/reject/redial/mute calls and adjust the volume. However, these headsets are paired with an industry first touch-screen base for call management. The 2.4-inch capacitive LCD displays caller ID, call records, and lets users switch between their mobile, desk, and corporate softphones via a spin of the carousel. Fun sure, and exceedingly geeky, but hardly worth the $199 to duplicate functions already built-in to the headsets or accessible via the displays on the devices it connects to. Then again, these are aimed at office professionals (read: corporations) when they launch in September and $199 is nothing when you're spending someone else's money.

Motorola isn't shying away from a fight here with its Endeavor HX1 Bluetooth headset -- and if there's anything the Bluetooth headset industry needs, it's some manner of controversy. The company is calling its new HX1 the "only Bluetooth headset to use true bone conduction technology," with a user activated "Stealth Mode" that switches the set from regular mic to an in-ear sensor which picks vibrations right off the bone for talking in particularly noisy environments. Jawbone, on the other hand, picks up vibrations from the outside of the face, but primarily as an "Activity Sensor," though the latest version nabs some audio from those vibrations -- both manufacturers naturally claim a military heritage to their technology. It'll take some actual testing to see who wins out, but it sounds like some good tech from Moto all the same. We do know one thing, however: no amount of in-ear stylings can ever ease your transition into general society. No word on price of a US release date for the HX1, it hits Asia in July.

Pretty strong words from Nokia calling its new BH-905 headset "the best headset ever made." The claim comes as a result of a partnership with Wolfson Microelectronics to add its 10-microphone "feed-forward" active noise-cancellation technology to the headset -- 8 mics for capturing background noise, 2 for your voice. The headset can connect wirelessly over Bluetooth or via a selection of plugs for your home stereo, MP3 player, or airplane jack. It also features high-performance speakers with stainless steel audio controls on one can, phone controls on the other. They'll hit globally in August for a steep pre-tax price of €285 / $403. Hey, that's not bad for the best ever.

It's been almost a year since Aliph last graced the Bluetooth headset world with its presence, and now it's back with the Jawbone Prime to reclaim the throne. The Jawbone Prime is only a minor update -- on the surface, anyways -- to its predecessor, and in fact the only visible change is a slightly different surface pattern and a minor indentation to denote one of the headset's two invisible buttons. Other than the quite welcome addition of Bluetooth 2.1+ EDR (multipoint connections, easy pairing), almost all the improvements under the hood have to do with the algorithm tweaks of NoiseAssassin 2.0 to improve noise reduction. It's really too bad the original isn't firmware-upgradable (we asked). The Prime will be replacing existing Jawbones at retail for the same old $130 pricetag, and comes in Blah Blah Black, Coffee Talk and Going Platinum, while an "EARCANDY" edition is available in Frankly SCARLET, 'YELLO!, Drop Me A LIME and LILAC You Mean It. Both will be available at retail on May 2nd.

Plantronics isn't planning to share intimate details about its Voyager PRO Bluetooth headset until April 23rd, but evidently its supply chain executives didn't exactly touch base with marketing before sending out stock to Best Buy. Jeff and John both managed to procure the $119.99 Bluetooth headset over the weekend, and we've got the shots to prove it. Based on the teaser site down in the read link, this here headset should be it's most advanced yet, but for a buck twenty, it better answer and respond to our calls without us having to intervene.

Update: Plantronics pinged us to say the price point here should be $99. Interesting.

Look out! You've just stumbled upon this week's episode of Ask Engadget, and we've got a real brain burner on our hands this evening. Before you dig in, though, feel free to blast your own question in to ask at engadget dawt com.

I recently got a new music-oriented phone (Nokia 5800 XpressMusic) with Bluetooth stereo audio (A2DP) and am trying to get some opinions on what might be the best solution out there for me. It seems to me like I have 3 options as far as general solution types: self contained Bluetooth headphones, such as the Motorola S9; Bluetooth receivers with headphone jacks, such as the SonyEricsson HBH-DS220; or transmitter / receiver pairs. My specific needs are that it supports remote control (AVRCP), has good sound, is under $100, and if the unit can bind to multiple devices that would be great. The ultimate item would somehow work with my phone as well as my PSP, but that's probably a pipe dream. Thanks!

So, wireless audio partakers -- what say you? Got any great tips? Got any horror stories? Either way, spill it below.

Since Oakley can't be the only company controlling the fashionable Bluetooth sunglasses market, TriSpecs has unveiled its own technetronic eyewear compatible with Bluetooth-equipped phones and PMPs. The eponymous shades sport two uni-directional mics, one touch dialing, and retractable stereo earbuds that hang at the tip of the temples when not in use. They're expected to hit retail sometime this month for just under $200 and come in black, white, and metallic options. Attractive model companion is, as always, not included.

Samsung swept into CES this year like an alien invasion. Tucked away beneath its awards, massive booth presence, and disrupter blast of products is this sexy Bluetooth earpiece. The Capella (shown tucked inside the receiver) is meant to be worn as a fashion accessory. Hey, that's what they say. And at the risk of being juiced by a Martian, well, we're not going to argue.

S1 Audio has shown up in Las Vegas with a plethora of new items to share, so share we will. Right out of the gate, we've got the neck-friendly NxSET Music 1 and NxSET Music 2 models, which are joined by the similar Mobile 1 and Mobile 2 models add Bluetooth for handsfree calling and the like. Moving on, we've got the SuperBudz 1 and Hypnos 1, both of which take the more traditional in-ear approach and include in-line volume controls and a completely stellar Turbo Boost for instant volume increases. Lastly, S1's wrapping things up with its dual purpose BudBud line, which is comprised of the Solo (a mono communications headset that converts to stereo earbuds), the MP3 (morphs from a single pair of 'buds to two complete pairs via the piggy-back design) and the Mobile, which includes a microphone for yelling at that guy who just yesterday was considered your best friend.

Sure, it's not as thin as the Bluetrek Metal or as eye-catching as the Swarovski crystal-infused Shimmer Kit, but iVoice's Diamond-X Bluetooth headset is sporting some very nice features, including noise-canceling dual microphones and the ability to report the callers' name from a phonebook. As for the other stats, we've got 5.5 hours of talk time and 200 standby. The Jury's still out on how convincingly it can tell us when our friend Slartibartfast gives us a ring, but for one Benjamin Franklin, you can find out for yourself later this month.

We all yearn for a life lived sans wires, yet many of us still find our media players dangling from the things. Mono Bluetooth headsets are already everywhere, but this could be the year that those of the stereo variety take off, and Altec Lansing's hoping its new BackBeat series will be a contender. They're made in partnership with earpiece-guru Plantronics, so callers will find integrated voice dialing, omnidirectional microphones, 7 hours of talk time, and AudioIQ to boost volume when you're in a noisy situation. For the music listener the sets include tune-channeling, canal-sealing buds, a behind-the-head band, and support for A2DP, AVRCP, HSP v1.1 and HFPv1.5. For those devices that list doesn't cover (we're looking at you, iPhone), the $130 BackBeat 906 includes a small transmitter. Everyone else can opt for the otherwise identical but transmitter-less BackBeat 903, which is $30 cheaper. We look forward to getting our ears on these at CES -- hopefully after they've had a thorough cleaning.

What's cooler than wearing your Bluetooth headset wherever you go? Wearing it clipped to a lanyard wherever you go, that's what -- especially when that lanyard is made from 8 inches of 25 pound tensile strength magcord (i.e. elastic). That's the power of bluDANGLE, a curiously capitalized name for what is basically just a clip that turns your wireless device into a wired one, swinging in the breeze whenever you're not actually making a call. Normally we celebrate any attempt that encourages people to remove their earpieces when not in use, but we're not entirely sure having the thing dangling from your lapel is any less pretentious (check out the vid below and you tell us). But hey, for just $19.99 with a lifetime warranty who are we to complain? Makes a great stocking stuffer for your family's Bluetooth guy (or gal)!

Not sure what exactly was so wrong with Blah Blah Black, Silver Tongue and Goldy Lips, but for those not really turned on by any of the aforementioned hues, you should probably set your navigator to the nearest Best Buy. Aliph has just introduced two new colors in the Jawbone family -- Babbling Blue and Rambling Rosé (shown after the break) -- which will be offered up exclusively at Best Buy Mobile. Same heralded Bluetooth headset, same $139.99 price tag -- just with two new tints.

This is it, soldiers. The day you've been anticipating has finally arrived. Okay, so maybe that's a build up not deserved by the lowly retail version of the Metal Gear Solid 4 Bluetooth headset, but seriously, we've been waiting ages for this thing to ship. Like, so long that the whole MGS4 aura has already come and gone. Those still firmly planted in Snake's posse can choose to prove their fanhood by snagging this thing now for $59.99; if all goes well, it should be headed your way in a matter of business days. Over and out.
