A: I'm assuming it means 25 db of passive reduction (That's what is actually saving your ears from getting damaged) and 40 db of active reduction (meaning that the earbuds take in surrounding audio information and play back the inverse to cancel sound. I don't know how much I trust the 25 db of passive protection though bc these tend to be more expensive if they are any good.
