I just treated myself to a new pair of noise-cancelling headphones that have me tap-dancing down airplane isles with joy…

As you may recall, a few days ago (as I pen these words) I flew out to Seattle, Washington, to give a talk to a bunch of engineers at Microsoft. While I was there, I texted my wife ("Gina The Gorgeous") to tell her I’d been told that there were 70,000 Microsoft employees scattered over the various Redmond campuses. She responded with a text saying “OMG!” which I thought was jolly enthusiastic of her. However, it turned out that she had misunderstood what I was saying and she thought I was giving my presentation to all 70,000 of the little rascals (I would have required a stadium the size of the Super Bowl venue :-)

During my outbound journey I decided to watch a free pilot episode of a new TV program called Franklin & Bash that I’d downloaded to my iPad. The quality of the video itself was wonderful. Sad to relate, however, I had only my old iPod earbuds in my backpack, which made it somewhat difficult to hear the audio track over the plane’s engine noise.

The thing was that I had also downloaded two science fiction films to my iPad, and I was looking forward to watching these little scamps on my return journey. Thus, I determined to treat myself to some new noise-cancelling headphones.

As an aside... The films in question were Monsters and Outlander. The first, Monsters, is about extraterrestrial lifeforms that were brought back to earth in the form of seeds / spores by a malfunctioning NASA space probe. We join the story six years after the probe crashed, by which time the entire northern part of Mexico is a quarantine zone.

The story follows two Americans who have been stranded in Mexico below the quarantine zone and who have decided to fight their way overland through the zone back to America. If you look at the reviews on Amazon you will see an average of only three out of five stars from 184 reviewers. This doesn’t seem so good, and normally I wouldn’t have gone further, but the positive reviews I read were very positive, so I decided to take the plunge and I’m glad I did.

This film isn’t for everyone. It’s not a fast “shoot-them-up” sort of film and the alien “monsters” aren’t “in your face” all of the time. This is a more thoughtful, slow-paced film with great cinematography and music. It’s hard to describe. I liked it. I probably won’t watch it again, but I’m glad I did watch it this time.

The second film, Outlander, is a combination of the classic tale of Beowulf with a science fiction twist. It involves spaceships and alien monsters overlayed into ~750 AD Norway. This may sound like a disaster waiting to happen, but in fact the end result is really rather good – great acting, fantastic special effects, and enthralling action that left me gripping my seat and thinking “There’s no way you would get me to go in there…”

But we digress… I already have a pair of Bose noise-cancelling headphones that I purchased two or three years ago (I’d left these at home because I wasn’t thinking). To be fair, the Bose do cancel out quite a lot of aircraft noise, but not as much as I’d originally hoped for. Also, they sit on top of my ears, so they start to become uncomfortable after a couple of hours.

With the leaps and bounds in signal processing algorithms and the increases in processor performance we’ve seen over the last few years, I decided that noise-cancellation technology had probably advanced a lot since I purchased my Bose. Also I decided that I should treat myself (who deserves it more than I?)

Thus it was that, on the return journey, I arrived at the airport early enough to give myself time to fight my way through security and check out the headphone offerings. I went to a little electronics store in the main terminal and – without much hope of receiving an intelligent answer (if the truth be told) – asked the young lad behind the counter “What are the best noise-cancelling headphones?”

He took me by surprise by being incredibly knowledgeable. He first said that it depended on exactly what I wanted. If I was looking for the best noise cancellation he would recommend the Sony MDR-NC500D; but if I was looking for the best possible audio quality coupled with a little less on the noise-cancellation front, then he would recommend something else (I can’t remember what the alternative was).

I opted for the Sony MDR-NC500D headphones and I have fallen in love with them. Quite apart from anything else they are easy to use. The main control is an On/Off button (I can handle that). There’s also a Monitor push button that disables the noise cancellation as long as you hold it down. I’m not sure exactly what this button’s reason for being is, but I found myself pressing it every 15 minutes or so just to I could contrast the huge amount of noise with the headphones disabled with how fantastically quiet things were when the noise-cancellation was active.

The Monitor, On/Off, and AI buttons are
visible on the right-hand earpiece

The other control is an AI (Artificial Intelligence) button. The guy in the shop explained that different planes have different noise profiles. A Boeing 747, for example, will have more base frequencies than a smaller jet. When you push and release the AI button, the headphones sample the ambient sound profile for a few seconds and then adjust their noise cancelling algorithms accordingly. Also, these little rascals are large enough that they fit completely over my ears, so they remain comfortable even after hours of use.

In one of the films (see above) there was a part where we were in a forest and the only sounds were crickets and birds and suchlike … and everything sounded as clear as one could hope. You really have to try these little beauties to fully appreciate just how amazing they are (but you will have to purchase your own – the only way anyone will get mine is after a fight when they pry them from my lifeless hands).

How much were these headphones? I’m embarrassed to say. I’m sure that they cost more in the airport and that you can get them cheaper on the web, but I wanted them then and there so that was that (if you see what I mean). Suffice it to say that I have never in my life paid so much for a pair of headphones, but I think they are worth it because I actually travel quite a lot in the scheme of things. In a couple of weeks, for example, I will be going to England to visit my dear old mom – and my new headphones will make my journey much more pleasant.

When you divide the cost of these headphones by the number of hours I will use them over the course of the next 10 years … they are still #$%^ expensive when I come to think about it … but I just don’t care because I’m worth it (grin).

Amazing so simple a concept brilliantly used by sony, an internal mic creating opposite sound to digitally cancel noise.
I'm in love with the innovation of Sony!

The price tag is quite high, one can by a tablet/netbook in this price :).
But well "its a Sony". Perhaps the price comes down with time.

I don't think Sony came up with the overall concept -- noise cancellation using an external microphone has been around for quite a while -- it is used by fighter pilots and other noisy environments...

The guy in the shop was at mains to note that these used "digital" processing -- I guess I would have assumed they all did, but maybe they are traditionally analog in nature...

These were expensive, but I think that I will really get a lot of use out of them in the years to come...

Sounds like a really nice set of headphones. I bought a pair of noise cancelling earbuds about four years ago, but was disappointed in them. Of course I wanted all noise and extraneous outside conversation cancelled from 0 to 20kHz! This purchase has got me thinking about the technology and wondering about its various implementations and limitations.

I'm from Seattle as well. I hope you enjoyed your visit to our fair city!

Sad to relate the technology isn't there yet that can detect, identify, and remove the sound of a screaming kid :-) But these really do do the best job of noise cancellation I've ever heard (or NOT heard in this case :-)

This was my second trip to Seattle, but I really didn't get to see much because I had so much to do... one day I hope to have time to "smell the coffee" :-)

I checked the price on line, WOW! I am glad that they work so well and that you like/love them. I will sadly have to wait.. It has been a number of months since I last flew and don't have any plans for awhile so I will keep the NC headphones on my radar and hope..

I must admit to being a bit embarrassed at the price...

...in fact they were cheaper in the airport than they show on Amazon -- and I saw another site where they were available for $199 (too late for me, of course)...

... but I do get to travel quite a lot... sometimes it's 5 hours to California ... other times it's 7 hours to England ... and then there's the occasional 12+ hour trip somewhere (like India last year) so I expect to get a LOT of use out of them (not the least that I always travel in the cheapest of cheap seats and stay at the cheapest hotels)...

...the thing is that when you get to my age you start to say things to yourself like "I can't take it with me" and "I deserve a treat"...

Clive,
I did the same thing 2 weeks ago, forgot to bring my headphones for my new color nook and had pre loaded it with movies and music as you did.

Same story, the kiosk girl in the airport was very sharp, knew exactly what I needed and was knowledgeable on all the different products and features. She offered demo units to try on.

I wont mention the brand, but it was only $99 and a very pleasant sales experience with someone professional and smart.

It was certainly NOT we are the shack and we have answers experience, where you are talking to a stick.

Hats off to they mystery pretty girl at Portland Airport, you are probably an engineering student.

Max,

You should check out the Etymotic Research ER-6i ($75 to $80) in-ear isolator earphones. Amazing sound quality, quiet as a church mouse, and a price that isn't embarrassing to talk about.

I use them all the time on airplanes and marvel at how effective they are.

I would love to try these -- if they are "in-ear" then you could also sleep in them which would be an advantage, but I'm not going to be spending any more money on headphones (or earphones) for the foreseeable future...

I just checked their site -- it seems that these have been discontinued -- also they weren't noise cancelling -- I find it difficult to believe that these would be as good as full-up noise cancelling -- but I would still love to try them...

Max, actually in-ear monitors (IEMs) have a noise isolation capability of up to over 40 dB compared to the mid 20-dB range for active noise cancelling headphones, which also usually only work for constant noise and over certain frequencies.

On the other hand, IEMs aren't for everyone - some find them uncomfortable, and cable microphonics can sometimes be an annoyance. Also, some (not all), like the Etymotics, stick out of the ear far enough that you can't really sleep on your side in them.

Good on you Max but I can never pay as much for a pair of headphones no matter how brilliant they are at noise cancelling! I would rather let nature take its course and get used to the engine's noise :-)

I was chatting to a guy in the office who said that he found a few hours of airplane noise to be very debilitating -- it left him tired and fractious.

I always travel in the cheapest coach seat money can buy (if you see what I mean) so anything I can do it improve the quality of the trip counts.

This was a one-off for me. I'd just been paid for a project and had covered all of my bills and decided to give myself a treat.

I have spent countless hours on planes -- typically I just read books and (as you say) get used to the noise. It was having my iPad that led me to start watching films and suchlike.

For my upcoming trip to the UK I have all the episodes from Dr. Who Series 6 Part 2 loaded on my iPad. On the one hand I do feel guilty about splashing out thsi cash for the headphones ... on the other hand I'm telling myself that after 30 years of suffering the aircraft noise it's time to "smell the coffee" and "hear the bird songs" :-)

I think that you have to weigh up the relative cost. Relative, say, to a cabin upgrade (which might not be quieter anyway). Then divide by the number of trips/flights/hours (I made around 12 round-trips in the last year, totalling about 40 individual flights), and the numbers start looking quite small.

I use these noise-cancellation ear-buds on longhaul flights to quieten the plane noise, usually with no audio running, which makes me less fatigued. They also sound pretty good with audio.

From an audio quality point of view these headphones are a lot better than the Bose ones. (I often listen to Alan Holdsworthian jazz, so I am always *very* analytical about the audio quality) and another strong point: There is no Micro$oft installed, so no updates or other things engineers really don't like in their spare time ;-)
