The problem is, for me, noise cancelling often either isn't enough, or creates a much bigger sensory problem when I inevitably have to take the headphones off.
And the settings with a big enough loudness problem to justify noise-cancelling tend to be ones where having to turn it off is inevitable before the noise dies down (to talk to someone)... so I usually don't bother.
Memes go in !risa, fan theories go in !DaystromInstitute, and Star Trek related off-topic discussion go in !Quarks, otherwise, I don't see why not.
