We have 2 pairs of Bose over-the-ear noise cancelling headphones and do not travel without them for any cross county, trans-Atlantic or trans-Pacific flights.
New Philips Noise-Cancelling Headphones Announced, Powered By Apple's Lightning Port You are using an outdated browser.
Dear Lifehacker, I work in a noisy office, and would love some noise-cancelling headphones. The goal is to create the strongest comfortable seal around your ears or ear canal so the only thing you hear is your music. Noise-cancelling headphones use digital signal processing (DSP) technology to actively cancel out the sound waves from ambient noise.
Most decent models can handle constant, ambient noise, such as conversations, air-conditioning units and engines. Trying to satisfy my persnickety audiophile preference for hearing fine details, timbral accuracy and precise imaging, while surrounded by the cacophony of planes or public transport, is almost pointless — not even the best of the current consumer noise cancellers can overcome plane and train noise enough to free up the more delicate, gauzy sonic details audiophiles like me chase. Jude explained that if you’re the type looking to wear noise-cancelling headphones while you travel or commute, your biggest concern should be the strength of the audio processor and the noise-cancellation circuit in the headphones you buy. So, for frequent flyers and public transportation commuters who do most or all of their headphone listening on planes, trains and buses, I think the primary consideration should be the effectiveness of the headphone’s noise-cancelling, and the most effective such headphones have good passive isolation combined with advanced active noise cancellation. To that end, he couldn’t help but praise the Bose QuietComfort 15s for their noise-cancellation circuit. If you have more cash, Jude suggested the Sony MDR-1RNC as an alternative that puts a little more emphasis on sound quality.
The noise-cancellation circuit in the MDR-1RNCs has three different modes (Office, Bus, and Airplane) that the headphones automatically switch among based on its audio processor’s assessment of the ambient noise.
If you’re looking for active noise cancellation and wireless audio, be ready to pay for it. You could always look into passive models, especially noise-isolating earbuds such as our five best (which really turned out to be five great IEMs), or look for great closed-back passive headphones if you’re looking to eliminate noise without spending money on active noise cancellation. Am still considering buying the non-amplified non-NC PSB's for at home though, as they are an incredible headphone. Originally bought because I was about to do some extensive overseas travel, and wanted to enjoy music and movies instead of the crappy hum of airplanes and snoring of nearby passengers. My experience has been that the difference in the noise-cancellation capabilities between a cheap pair and an expensive pair is fairly small - I've got a pair of $40 Digital Silence ones that cancel out noise in a crowded bus or on a plane as effectively as my $350 Sennheisers. The main thing to remember is the same thing you should remember when looking at gimmicky 'surround' headsets - everything that's not the main pair of drivers costs money, and every dollar spent on other things is a dollar less spent on quality drivers. Worse, the nature of active noise cancellation is that it alters the waveform that you hear, and the quality is reduced, no matter how good the set is.
So the question comes down to this: is active noise cancellation worth spending 30%+ more on than an equivalent passive set?
Yeah true, they block out so much noise, and I actually think I prefer the triple flange to the custom molds for some reason. That said when flying I have taken them out as the plane was coming into land and there was a screaming baby and I asked the person how long has it been screaming for and they said since before take off. You don't need cancelling just isolation should be enough with a decent enough sound and volume you should be good.
Warren King works for a national motorsport organisation, travels frequently, and is an avid gym-goer. Like most guys in their late-twenties, music videos of Bieber, Justin and Miley don’t exactly fill me with desire to lift heavy weights at the gym (and put them back down again, rinse, repeat). Prior to sticking the QC20i buds into my ears, I had been going strong with a pair of Klipsch S4i (Series 1) headphones with Comply foam tips for better isolation (never been a huge fan of silicon tips).
While I wouldn’t refer to myself as an audiophile, sound quality and fidelity are both important to me, so if a headphone crackles under heavy bass, it’s out. With all of that in mind, I can gleefully report that I have found the Bose Quiet Comfort 20i noise cancelling headphones to be an absolute pleasure. The accompanying headphone pouch is embossed with a circle pattern and the Bose word mark while the headphones were presented on a plastic tray. Next, I plugged the ‘phones into my iPhone 5 and gave some music a crack and was greeted by warm tones and a slight emphasis on bass (not Klipsch levels of bass, but definitely decent).
The 3.5mm connection at the end of the headphones is also an underrated factor in headphones and can determine whether they end up being frustrating to use. After packing the headphones away at the office, I was excited to give them a test-run at the gym that evening. Whilst I haven’t tested the noise cancelling module or an earbud by dropping a weight on it, any incidental bumps had no effect and nothing felt fragile. With a successful office road test and being put through their paces at the gym, I was VERY eager to try these things out at the racetrack. Cars hit the track, the flag went green and I popped in the QC20i’s… I could still hear the cars pretty clearly.
While I’m on the subject, you CAN listen to music through these headphones without the noise cancelling module turned on (or out of battery). As I mentioned earlier, I have had some niggles as I use them more and more, but the following is strictly nitpicking given the high standard of the product. As I have continued to use the headphones, I’ve become accustomed to the noise cancellation, and I’d say on balance I can hear outside noise a little more than the first few uses, so this is something to consider. The aforementioned sound quality sans-noise cancelling is an issue if you forget to charge them (they get a good amount of life though, and the light will flash when the battery gets low), and if I’m extra critical, a hard case instead of a pouch would have been a great inclusion for something that costs $400 Australian. I’m looking forward to continuing to put these to great use, and I can’t envisage a scenario where I would choose another pair of earphones over these unless the noise-cancelling battery went flat on me. If you’re in the market for headphones and the price tag doesn’t phase you, I say pull the trigger — you won’t be disappointed. As far as I can tell, the AWARE mode actually adds noise through the microphone, so you will actually pickup more background noise than conventional earphones as a result, although obviously this is intended. They work best with constant background noise, and tend to be fairly good at incidental noise.

Also, at the gym, if the music through my headphone fades out at the end of a song or there is a silence gap, I can still hear the gym's music faintly coming through the TVs, but again, greatly reduced volume and with no other background noise. You can activate the Sony noise cancelling feature then turn on and off the simulated airplane engine noise to hear for yourself the before and after. The headphones were on display in a showcase at CES 2015.The Fidelio NC1L noise-cancelling headphones use the same 24-bit digital-to-analog converter as its establisher.
To that point, noise-isolating headphones are usually designed to be operated at lower volumes than others, since outside noise will be muffled.
However, sharp changes, such as someone shouting or a door slamming are difficult to adjust for. Plenty of models boast noise isolation or active cancelling, but some do it better than others, some do it at the expense of audio quality, and others are just flimsy budget headphones that do little more than crank up the volume to drown out the noise. Beyond active and passive or noise cancelling and noise isolating, You should also familiarise yourself with the types of headphones available and decide whether you’re in the market for earbuds (or in-ear headphones), earpads (or supra-aural headphones), or full-sized headphones (or circumaural headphones, that fit around your entire ear). Since active-cancelling headphones have their own audio processor, the quality of that processor (and its circuit) factors heavily into the price of the device. If you have the option, try on the headphones you want to buy and toggle their noise-cancellation system. Almost all of them are designed to give you peace and quiet more than emphasise the nuances in your music. Beyond that though, I found their noise-cancellation circuit to be on par with headphones much more expensive that I’ve tried. The QuietComfort series is the market leader for a reason, and while that reason isn’t necessarily audio quality, they do have exceptional noise cancellation.
The entire class of headphones are relatively expensive, but active noise-cancelling Bluetooth headphones all also come with features and audio processing designed to make up for the inherent loss of audio quality that’s synonymous with Bluetooth.
I've had my pair going onto almost 2 years now, and they still sound as fantastic as out of the box!! I sat in quiet spots like the back of a Airbus 360, to drum blowers like the wing seats on a Turbo-Prop. They may be great for otherwise quiet offices, but they’re not going to make it easier for you to sleep on a plane, that’s for sure.
If you want to actually listen to music in a way that doesn't make it seem like your ears are connected to a metre-long cotton-filled tube though, spend more money. I love them on plane trips as I can hardly hear anything once I am listening to anything even without them blearing. Safe to say he spends a lot of time with earbuds securely fastened to his lobes, attempting to isolate himself from the outside world. These have served me well, but I’ve been searching for a new pair of earbuds for some time.
They have become my absolute go-to headphone of choice, and while they do have shortcomings that I will mention, the positives FAR outweigh the nitpicking negatives. I was impressed (and continue to be) by the build quality, especially the heavy-duty cabling — often a niggle of mine with headphones. I would never expect a pair of headphones to require a Mensa-certified operator, but I was unsure given this is my first proper foray into the world of noise cancelling earbuds. It initially felt like my ears needed to pop (not unlike taking off in an airplane), but that sensation faded after about 5 minutes. Mid tones seem clear and strong to compensate for “less” bass and the treble was neither distant nor harsh – a very pleasant listening experience right off the bat. Bose have opted for a 90-degree plug, but unlike plugs from Beats By Dre that sit flush with your phone, Bose have given some clearance from the device, so use with most cases should be largely no issue. She reported I could be heard loud and clear, and I had no issues in a noisy environment understanding every word thanks to the noise cancellation. My workouts at the gym consist of weight training, 95% of the time using barbells and dumbells. Also, while the noise cancelling module is such that it is easy to sit alongside a phone in your pocket, it IS pretty noticeable.
If you’re considering QC20i earbuds and just need someone to reaffirm that you’re making the right choice — buy them (you’re welcome). I'm actually off to the States in a week's time to NYC and Minnesota and will be seeing a few games - (not) looking forward to the ~50 degrees C net temperature change! Obviously, the box has to hear the noise with it's microphone, process it, and then play the anti-noise.
For example, I could still hear engine noises at the track (a combination of incredible volume AND changes in noise frequency), but the noise was GREATLY reduced, even without music playing. In an office situation, it's basically like being submerged under water into complete silence with all surrounding noise removed.
Google hopes that within a couple months, apps will move to a stable beta release and finally work on Chromebooks this spring. If you don’t already have one, you can try this Sony Noise Cancelling Headphones MDR10RC.
The digital-to-analog conversion that usually occurs inside the device can now be processed by the headphones.
One just tries to minimise the amount of extra sound that gets into your ear, and there’s serious technology behind the other. Basically, noise-isolating headphones block out noise by creating a good seal between your ear and the headphone. Similarly, you should be careful wearing them when out and about, since you may not be able to adequately hear your surroundings. However, there are some great options out there for you that can keep you well entertained while giving you the peace to focus on your work. You’ll need a pair of AAA batteries for them, and the earcups swivel around to store flat in their (included) carrying case.
Jude explained that the QC15s were the best of the commuter-friendly noise-cancelling headphones he’s tried.

Jude suggested the Logitech Ultimate Ears UE9000s because of their build quality, 20-hour battery, and its flexibility as both wired and wireless, active and passive headphones.
However, if you’re serious about your audio, and you really want a pair that will offer you both active noise cancellation and great audio, you should be ready to pay for it.
If you're a purist when it comes to your headset audio, none of these things are desirable. The cables have an almost pipe-cleaner like sturdiness to them that reminds you that this item is built to last, and also seems to prevent any rustling interference from the cord rubbing on your clothes.
Take out the headphones, choose a size of ear tips (I eventually settled on the large size), switch on the NC module and enjoy the serenity.
The first use was at my desk at work, but we had a worker rendering our building outside my window (with tourettes-level swearing issues) and a truck idling in the parking lot about 20 metres away — this immediately died to a distant hum when I flipped the little silver switch on the noise-cancelling module.
I always feel like I may be yelling when talking handsfree and my own voice sounds muffled, but apparently I was at a respectable volume throughout the conversation. The first round was on Boxing Day in Adelaide, and I was keen to see how the earphones coped with the scream of twenty 900hp, 410ci V8 open wheel race cars hitting the clay. And to account for the module, the cable could stand to be about 10cm longer — the current length is fine, but some extra give wouldn’t go astray unless you’re comfortable with the module hanging out of your pocket in the open (I’m not).
This eliminates the analog audio signal having to be transfer through a long headphone cable – which is usually interfere with or degrades along the way.One of the more noticeable aspects is the noise cancellation. Should I just buy a pair of Bose QuietComforts, or are there specific ones you’d recommend? Let’s describe the differences first, then we can talk about what to look for in a good set of headphones. Again, these are headphones you should be careful wearing when you’re out and about, because the goal is to eliminate noise from your surroundings.
Personally, when I use active cancelling headphones, I prefer full-sized models that fit around my entire ear — it helps add a passive hand to the active noise cancellation system.
If they’re active, put them on your head and turn them on in the middle of the store. They’re light, comfortable and easy to wear, even on long flights or long hours in the office. He noted that they sound good when wireless and active, but if you can sit down and plug them in, you’ll get a better audio experience that may make the flexibility and portability worth the extra cash. I also have a good isolating headset that cuts out almost all low-range noise anyway (active noise cancellation only works effectively on low-range noise) so there's no incentive for me to pay more for a worse experience.
This means the headphones need to be a number of things: sweat resistant (to a point), durable in case of accidental knocks, lightweight to prevent being annoying in the middle of a lift, and stable.
I would not hesitate to recommend these headphones for any motorsport enthusiast that values his or her hearing – you still hear the cars but don’t go deaf.
I understand how this would work well when there is a fairly constant noise, like onboard an airplane.
This is accomplished by using four microphones to monitor external buzz before inverting it to cancel out background sound.Although this is nothing new but it is duly noted that the noise-cancelling headphones require batteries to keep running.
Over-ear models that fit all the way around your ear have thickly padded cups designed to block out as much outside noise as possible. Plus, they’re everywhere, so you can try them on before you spend the (admittedly expensive) cash on them. Using these without noise cancelling on is like using candles during a power failure — you put up with them, but you spend the whole time wishing the damn lights would come back on. We are not paid to express favorable opinions or otherwise about any product, service or about Costco itself. Since the Lighting port can also provide power, the headphones will not have use for external batteries.A Philips representative said he is sure that the power won’t noticeably drain the battery life of your Apple iPhone. This doesn’t mean there aren’t bargains to be had, but those $40 no-name noise-cancelling headphones you picked up online? If you’re with someone, try having them talk to you at different distances to tell whether you can make them out. Grab a couple of your favourite songs and load up your smartphone or media player with them. Apple is said to be very strict about how much electricity is to be drained by third-part accessories from the Lighting port.Philips say they are excited about the possibilities by using the Lighting port.
Your friend won’t be able to simulate a jet engine, but they will be able to simulate office chatter from a few cubicles down. You could also load up a few Eminent multimedia test files too, and see if you can actually plug the headphones into your own device at the store. The last thing you want is to spend $300 on a pair of beautiful headphones, have them die on you and get the old customer service runaround. This is particularly because it could be able to deliver firmware and sound profile updates to the headphones through its iOS app. Again, you don’t have to empty your wallet, but the best models are in the hundreds of dollars, not the dozens. You’ll get a better feel for what your music will sound like, coming from your own device, with the noise cancellation on and off.
Another factor that the company is excited about is that users will have the ability to customize performance to better cancel noise in certain environments. The downside is if it's not in my pocket, i find the cable around the jack gets a bit of a workout.
Will they get uncomfortable on hour two of a six-hour flight or will they start to make your ears hurt while you’re sitting at your desk? Even worse, will you get tangled up in cables if you want to wear them while you’re cleaning out the garage?
