Active noise-cancelling only seems to work (in my very limited experience) with 'constant' noise though - predictable. Spoken conversations often aren't. But, I might've just had a bad experience with those in the store. I'll stick with passive noise cancelling / in-ear with foam things.

Or, you know, tell people to be quiet.

Currently working at a growing startup in Waterloo, it's an open office with a lot of people and it can quickly become very loud (picture 150 people in a big room).

I completely agree with you, without music, noise cancelling headphones are pretty much useless to help you focus by canceling 'asymmetric' noise.

My personal setup is to have a pair of earplugs in resina as a first layer, my headphones as a second layer, the noise cancelling option on and finally low volume music. With that setup I can't hear anything to the point where I get scared shitless if someone disturbs me. That's how deep in the zone I become!

Solution for this was proposed in Diamond Age by Neal Stephenson. Engineers were working in big room, but they were so focused, guests had to use special protocol: stand beside desk and wait quietly until you are noticed.
