I've used Bose Quite Comfort (the I or the II, not sure anymore) in the trading floor of an Investment Bank (think fishmonger's market but with financial assets) back in the late 00s to be able to do software development (which requires focus and concentration to do efficiently).

They most definitly block outside noise (still do, in fact, over a decade and 2 earcup replacements later).

Still work fine. Somehow the "condensation" "problem" was already solved a decade and a half ago.

Oh and even though noise-cancelling tech in headphones was near-bleeding edge back then, which is not at all now, they cost roughly half as much as these airpods which fail "due to condensation" (though inflation adjusted and using the higher GDPUSD cross-exchange rate from back then, it's maybe only 2/3 as much)
