I live in NYC and I'm a longtime user of the Bose QC20s. They are probably the best commercial noise cancellation devices. I even sleep with them. The article promises some significant leaps in the technology. No doubt as processing gets faster and smaller we'll have even smarter noise cancellation. Looking forward to that...

Can't they stop human voice, music and children crying?

These three are literally the only things I want to filter out while I'm focusing.

I have some of the best noise cancelling headphones (Sony MDR-1000X) and the thing few people realize is that active noise cancellation actually increases perceived pressure on your ear. For me it's like being underwater. I'm only really using them while flying.

I had both the MDR-1000XM2 and the Bose QC25, and the QC25 actually feel more like underpressure. I don’t think feeling overpressure is inherent to noise cancelling. I suggest you try out the QC25/35 in a store and see if they feel different to your ears.

> I even sleep with them I used to do that with my QC15 first and then after it broke twice, with my QC25 replacement. Sleeping with them on is really tough on them, though. After the third replacement device, I decided I couldn't keep on doing it no matter how much I actually enjoyed putting it on at night and hear that soft static. The slight pressure actually felt pleasant. Quitting using them for sleep was hard,…

They make a pair for sleeping with if what you want is white noise: https://www.google.com/search?q=bose+sleepbuds

It isn't exactly white noise that I am looking for. It is the residual waveform QC25 has after it has done its best effort at noise cancellation.

With that being said, after looking at here [0] it actually looks pretty promising although it seems to not have active noise cancellation.

I have the QC35 and it feels like overpressure to me. Might be an individual thing.

It seems like this would require an array of microphones, plus knowledge of the user's location, mushed together into a model of the environment. Like MIMO for sound.

Completely agree. With only one microphone placed somewhere around the cubicle it would not be able to detect the direction the sound is coming from. In worst case the sound wave reach you before the microphone... Also in order to create the perfect anti wave the distance between you and the microphone has to be known really well. I think this is actually one of the huge advantages of wearable noise canceling headphones.

Yep, same headphones and I get the same sensation. It doesn’t bother me too much but when it’s not too noisy I leave the noise canceling turned off for that reason.

I'm assuming you've tried basic earplugs with white noise generator at full power? When I used them to block out building construction noise, they worked well. Maybe even too well - I was wondering if I'd wake up if a fire alarm went off. Active noise cancellation doesn't work well with noises like ambulance sirens.

That aside, I found that construction earmuff is quite good for blocking sound and gain focus — with just about 5% price of top noise canceling headphone in the market. It took a bit getting used to though(and took quite some times to 'stretch' the earmuff in order to make it not clamp too tight to your head, but it works quite well and very cheap alternative. It looks derpy though so I can't wear it in the office —…

Heh, most people think mine are headphones. The derp factor only occurs once they figure out that they're not. :)

You can get earmuffs that are also headphones. I know Sennheiser collaborated with Peltor on some, a couple of years ago.

I was on the fence about them. I had the Sennheiser BTNC 4.5 shortlisted since they're cheaper. Is Bose's noise canceling significantly better than Sennheiser's?

I can't rate Bose vs Sennheiser, but I can tell you that my $300 Bose QC35 II is far, far more effective than either my $100 Creative HN-900 or my SO's $100 Audiotechnica QuietPoint ATH-ANC7. I have a friend with both the Bose QC35 II and the $300 Sony WH-1000xM2 and he rates them about on par for noise cancelling, but puts the audio quality on the Sonys a little higher. The two cheaper models are garbage by comparis…

Those Sony headphones had a defective design, the plastic would crack consistently in the same spot. You can get a sense by going through the products web page on Sony’s website

You'll be fine. A guy in our office wears some, it's no big deal.
