Pioneer's SE-NC31C-K noise-cancelling earbuds are cheap, but are they effective?
Active noise cancellation's the secret sauce that keeps us counting sheep even when surrounded by the cacophony of crying babies and the dull roar of jet engines -- though we often find the bulky form factor of those serenity-inducing cans unwieldy. Luckily for us, Pioneer has released its SE-NC31C-K noise-cancellation earbuds that promise to remove 90 percent of ambient noise at the flip of a switch on its AAA battery-powered in-line module -- all for around a hundred bucks, which is a far more palatable price than its sound-suppressing brethren from Sennheiser ($320) and Sony ($415). Should you run out of juice, fear not, for you can bypass the noise cancellation features to listen to your tunage as you would with a garden variety set of buds. Given its (relatively) bargain-basement price, we aren't sure how well Pioneer's latest nullifies ambient noise, but there's only one way to find out if they can give the best headset ever made a run for its money. Should you not share our skepticism, hit the source link and grab a pair for yourself.
GM shows off Terrain SUV with noise cancellation, says silence equals fuel efficiency
GM claims its new Terrain has other SUVs beat when it comes to fuel efficiency, and they're citing active noise cancellation -- a concept near and dear to audiophiles everywhere -- as one of the driving factors that puts it 4MPG above the competition. Basically, the Terrain's enlisted a new one-touch "Eco mode" that allows its four-cylinder engine to run at a lower torque, decreasing engine speeds, and thus saving gas. The thing is, this increased fuel efficiency comes with a "low-end frequency boom," which is where the noise cancellation sets in: two microphones built in to the car's headliner detect the boom, prompting a frequency generator to pump counteracting sound waves through Terrain's speakers. Simply put, GM's just getting rid of an unpleasant hum. So a quieter car isn't necessarily a greener car, but we'll take a more fuel efficient SUV any day. If you're picking up what GM's laying down, check out the full PR after the jump.
Ask Engadget: best (non-ugly) noise-cancelling Bluetooth headset for drowning out office noise?
We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Simon, who seems to be not-so-secretly hoping to drown out his entire office. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com. "I need a headset which can block out the background from a busy office. I'm talking repetitive noises such as drilling, background chatter, keyboard clattering, computer fan whirring and the endless static from our building's air conditioner. I would love if this headset had a fair to good quality of sound for MP3s, and it would of course have to have a good microphone for IP phone telephony and Skype. If it didn't look like something from Radio Shack that would be a bonus, and if the microphone was a bit discreet for street and airplane use that would be an added benefit. Lastly the connection to a workstation could be both USB and Bluetooth, with a preference for wireless. Thanks!" Bluetooth headsets have evolved quite a bit since the last time we had this discussion, so we're curious what you're currently using to make work a wee bit more bearable? No need in keeping secrets, right? Speak out in comments below!
NEC uses active noise cancellation for quieter zooming into your future memories
NEC just injected a little Bose up in some digital cameras, adding what it calls "noise suppression technologies" to Casio's new EX-ZR10 and promising that it will be deployed "throughout the digital camera and video camera markets" soon. The tech is designed to combat the evil intrusion of noise from optical zoom motors, working with a recording of what the zoom motor sounds like inside the camera. The shooter's internal circuitry then subtracts that noise from what's being recorded and, hey presto, silent zoomin'! NEC indicates a camera's microphone still captures other, desirable ambient noise without issue and that this tech allows the use of faster, more powerful motors for faster, more powerful zooming.
Sennheiser's sophisticated CXC 700 earbuds tout three levels of noise cancellation, TalkThrough functionality
Sennheiser has a thing for trotting out titillating new wares at the annual Consumer Electronics Show, and this year is proving to be no different in that regard. The audio specialist has just introduced one of the most fully-featured headsets we've seen in quite awhile, with the CXC 700 boasting not one, not two, but three levels of noise cancellation. The newfangled NoiseGard /digital technology gives owners a trifecta of noise-cancelling profiles, with each one optimized for something different. In fact, we'll let Senn do the explaining here: "Mode 1 absorbs low-frequency noise in particular (100 to 400 Hertz), such as engine noise from trains, buses or small passenger planes. Mode 2 focuses on cancelling noise in the medium frequency range (400 to 3,000 Hertz), which is caused above all by air-conditioning systems in large passenger aircraft or office buildings. Mode 3 has a particularly wide frequency range (100 to 3,000 Hertz), and combines the noise-cancelling effect in the medium and low-frequency ranges. As a result, background noise with different noise components, such as that which occurs at airports, railway stations or underground stations, can be effectively suppressed, although with a slightly lower noise-cancelling performance than in the first two modes." In case that's not enough to convince ya, these offer a frequency response of 20Hz to 21,000Hz, and they'll function just fine (albeit sans noise cancellation) even if your AAA battery keels over. Controls are embedded in the cabling, and users are able to activate the TalkThrough function if they'd prefer to conduct a conversation with someone without actually removing their earphones. Furthermore, changing between the NoiseGard profiles and activation of the TalkThrough function are indicated by both an acoustic and a visual signal. The company will be shipping these with a 4.5-foot long cable, an in-flight adapter, 6.35mm jack plug adapter, a small carrying case and a diaphragm protector, with sales to start later this month for around $320. %Gallery-112244%
Ask Engadget: best passive noise cancelling headphones?
We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Alex, who just can't take the noise, dude. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com. "Hello Engadget. I've always been a fan of high quality audio but I have a problem. I need noise cancelling headphones, but active noise cancelling gives me a headache and my ear canals aren't round enough to use in-ear earphones. I've also looked into custom earphones but I can't afford paying $400 or more for a set. What are your recommendations for the best pair of passive noise cancelling headphones? My ears thank you." We will say that Klipsch's oval ear tips tend to fit in funky ear canals that typically reject round ones, but if you're still hellbent on a pair of cans, we're hoping our audience below can toss out some advice. If they can hear us from underneath their noise cancelling headphones, of course.
Cardo Scala Rider G4 headset review: advanced noise cancellation for riders
We'll get this out of the way up front: riding a motorcycle on the road is a generally dangerous and frequently challenging thing. Doing so while dialing into a concall or grooving to some chill tunes is, well, not something we would exactly encourage. So, when we were given the opportunity to test ride Cardo's latest helmet-friendly Bluetooth headset, the Scala Rider G4, we were a little unsure of just how useful the thing would be for a conscientious, safety-minded rider. We took a pair of the headsets for a spin just the same and were left firmly convinced that this is a product worth giving up our in-helmet singing careers for. Click on through to read why, and for a demonstration of some supremely impressive noise cancellation. %Gallery-88850%
Sony's Trik / Triq iPod Dock is perfect for your garishly tasteless lifestyle, also headphones
Looking for the perfect sound system to match the urban camo scheme you applied on your M4A1 in Modern Warfare 2? Have we got the solution for you, guaranteed to both work with your iPod/iPhone and to make your parents cringe. It's Sony's Triq/Trik, which is so unbelievably tricky Sony can't decide whether to call it the Triq or the Trik. If the monochrome thing doesn't do it for you there are three other skins to choose from, each more hideous daring than the next. It pumps out a very meaningful 75 watts and will cost a $130 when it ships in April. Sony also announced the MDR-NC300D Digital Noise Canceling Earbuds, said to be the first earbuds with digital noise cancelation, surely far superior than those paltry analog cancellation-featuring earbuds. They're pictured after the break, featuring a "vertical-in-the-ear" style and providing 20 hours of life from a single AA battery. No, the battery doesn't go up in your ear canal. %Gallery-81805%
Sony NWZ-S745 on sale in Canada, US given cold shoulder
We don't know about you, but every time we hear of a Walkman, we think of the old school cassette players, and are left strangely disappointed by the slinky modern variants and their tons of storage. The 16GB S745, which has absolutely nothing to do with Mickey Mouse we assure you, has entered North American retail channels, only it seems to have skipped the US for its more peace-loving neighbor up north. Eagle-eyed Canadian shoppers have spotted the more advanced version of the S740 on sale in Sony Style stores (for 200 CAD or 188 in real American currency), replete with a 2-inch screen, noise-canceling earphones, and an unhealthily thin case. Still, suspicions abound that Sony is merely waiting for CES to roll around to make its big US unveiling, but if you really can't wait it's not like driving up to Canadia would be that terrible anyway.
Video: Sony NW-A840 packs OLED, noise cancellation, and 64GB of flash heat, still thinnest Walkman ever
Sony's keeping the pressure on the dedicated portable media player market with the launch of its latest OLED Walkman. The NW-A840 series is the thinnest Walkman ever at 7.2mm and comes packing a 2.8-inch OLED display and up to 64GB of flash storage. The players also feature Sony's digital noise cancellation, premium MDR-EX300SL earbuds right in the box, and the ability to pump 720x480 pixel video out to your TV. Sony rates the battery at 29-hours of continuous music or 9-hours of video. The A-series ships in three models -- 16GB NW-A845 (¥24,000/$263), N32GB W-A846 (¥30,000/$329), and 64GB NW-A847 (¥40,000/$439) -- starting October 31st. Also available in black for those who detest downtown hipster-brown. Video preview after the break. [Via Sony Insider]
Video: simulated 'quiet zone' cloaking hides an object in 2-D
You don't have to be able to pick a Romulan out of a crowd of Vulcans to be intrigued by the idea of cloaking, and indeed many non-trekkers have tried to hide things in plain sight using electromagnetism, acoustic superlenses, or light-bending materials. The latest attempt relies on devices that emit cancelling waves of the sort anyone who's ever seen a Bose commercial should quite familiar with, combining to negate any external, incoming waves. What's different here is that they also recombine on the other side of the object being cloaked, as shown in the video below, meaning that incoming surge is then re-generated and continues on undisturbed -- potentially even reflecting back through the object again should it hit something on the far side. It's part of research at the University of Utah and, for now, only works in a theoretical two-dimensional world where triangles and squares are ruled by pentagons, hexagons, and priestly polygons. Optical camouflage is sadly not believed to be possible using this technique, but sonar and radar are likely implementations, as well as mechanisms to subvert earthquakes, tsunamis, and maybe even neighboring speed metal fans.
Nokia's world-beating BH-905 Bluetooth cans slip into the photo booth
Nokia's BH-905 made some serious waves when it debuted back in early June, but what else would you expect from a product that calls itself "the best headset ever made?" The Bluetooth-equipped cans, along with its ten microphones, supple ear cups and A2DP / AVCRP support, are expected to launch globally next month for around three hundred bones, and the fine folks over at NokNok have already managed to score a pre-release model. Aside from visibly gushing all over themselves, they also note that the cans are far smaller than the original press shots made them seem, giving cautious travelers reason to breath a sigh of relief. Hit the read link for a luxurious hands-on look.
Creative's Fatal1ty Professional Series Gaming Headset MkII hands-on, and news of its sequel
Cans are so hot right now; the bigger and gaudier the better, because nothing says "Don't talk to me" like giant domes covering your ears. Creative's latest set, Fatal1ty Professional Series Gaming Headset MkII, don't really have much to offer in the flash category and certainly aren't excessively sized, but for serious gamers they seem to be a solid option and just the thing to keep your mom from interrupting your session. Shipping next week for $99, they offer an over-ear design with memory-foam surrounds and a sophisticated but not particularly flashy look that says "I want to look cool while wearing these, but I'll leave the chrome to my CPU fan, thanks." They sport a detachable boom that has not one but two microphones in it and some apparently fancy-schmantsy processing that can discern your howl of war from your dog's howl of neglect, meaning your CS teammates hear only the former. Unfortunately we weren't able to try that out for ourselves, so we'll have to see how well that pans out in the real world. The set uses the standard jumble of 3.5mm audio jacks to connect to your machine, but a Creative rep was kind enough to disclose plans for a USB version that'll work sans-soundcard. That model is due sometime next month for a $30 premium.
Nokia's Bluetooth BH-905 is 'the best headset ever made'
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.[Thanks, Stephen R.]Read -- AnnouncementRead -- Microsite with video
Toshiba's auxiliary speaker cancels noise from main speaker
Er, something like that. Reportedly, Toshiba has conjured up some sort of newfangled technology that's able to more accurately reproduce sound by using a noise canceling auxiliary speaker. Specifically, the tech utilizes "sound from an auxiliary speaker to eliminate noise generated from the main speaker," and in case your wild guess wasn't good enough, it relies on "opposite-phase sound waves generated from the auxiliary speaker attached to the main speaker" to make it all happen. We know, our head is spinning just as fast as yours here, and it's all the more difficult to comprehend without an actual product to demonstrate. That said, Tosh is planning to conduct research and development in order to implement this into its own products, so hopefully we'll be seeing something a touch more tangible real soon.
Hitachi Maxell intros noise canceling, battery draining iPod headphones
If short, intense sessions with your iPod are your bag, these new Maxell heaphones might just do the trick. Compatible with your fourth-gen iPod (or your first and second-gen iPod touch) the HP-NC20.IP earbuds offer active noise cancellation from 50-700Hz and noise suppression up to 20dB. Since they rely on the iPod dock for audio and power, you're stuck using the volume control on the headphones themselves, and battery life is significantly reduced -- anywhere from one half to two-thirds. If you're one of those people who never stops rocking, you might want to stick to something a little more passive, headphones-wise. But if you tend to "rock out" in concentrated amounts, these just might be the earbuds for you. Due to hit the streets of Japan on December 12 for a retail price of ¥8,000 (about $83).[Via AV Watch]
SoundSense unveils sophisticated Noise Cancellation System for audio purists
For home theater owners that love audio as much as (if not more than) video, unwanted noise is a real downer. Thankfully, the sound engineers at SoundSense completely agree, and now the company known for its acoustic dampening solutions is delivering a Noise Cancellation System that reportedly eliminates all that excess noise when you fire up your speakers and amplifiers. Put simply, the process simply utilizes a small microphone and speaker; the "noise-canceling speaker emits sound with opposite qualities of the noise source, thus eliminating distracting sounds." We've no idea how costly said solution will be, nor if it will be easy for novices to use, but don't hesitate to give SoundSense a call and see what it'll take to zap the interference lingering in your HT.
Radius' noise-canceling earbuds for your iPod nano
Got a third-generation iPod nano? Looking for a new set of earbuds, preferably with noise-canceling abilities? If so, look no further than Radius' new set, which plug right into the dock in order to extract all the juice they need to block out extraneous clamor. The radStrap canalphones are expected to ship in black, green and silver, and feature a neck strap, on / off switch for the noise-cancellation, an aluminum housing and frequency response of 20Hz to 20kHz. Check 'em out next month for ¥8,980 ($82), but don't get your hopes up for a bonafide US release.
Sound ID's SM100 Bluetooth headset tunes you into nature
We've got Bluetooth headsets that cancel noise, amplify voices, and make you look good not entirely cockamamie, but Sound ID's latest iteration actually gives you one less reason to ever take it off. The minuscule earpiece sports compatibility with handsfree Bluetooth profiles, around eight hours of talk time and 72 hours of standby, auditory and visual low battery warnings, dual omni-directional silicon microphones, and a trio of modes to fit your situation. It also touts a NoiseNavigation feature that magnifies and cancels appropriate sounds automatically, and just in case you get tired of only hearing face-to-face conversations out of one ear, the "Environmental Mode" actually brings in ambient noise in order to make you forget about the critter hanging off your eyeglass holder. Notably, the $129.99 SM100 even features a One2One mode that enables "Bluetooth communication between two modules" without the use of a cellphone, which should definitely appease the anti-social social crowd.[Via Slashphone]
Hands-on with Aliph's Jawbone Bluetooth headset
What makes a Bluetooth headset great? Does it need to be so small as to be virtually invisible? Does it need to be a brilliantly-designed fashion accessory? Perhaps easy to use, easy to hear, and easy to be understood? Ultimately, of course, no model is perfect; every headset on the market is a compromise, a reflection of the manufacturer's (and the buyer's) priorities. So we basically went into the review of the Bluetooth variant of Aliph's lauded Jawbone with that same mentality, hoping that it'd prevent us from getting distracted by any miscellaneous shortfalls in the product -- the Jawbone's draw, after all, is its noise reduction circuitry, and that's what we really wanted to report on here. Instead, we came away with a shockingly positive impression of the Jawbone not just as a technological overachiever, but as a legit headset that we could see ourselves using day in and day out. Read on to find out why.
