Just keep in mind, noise canceling headphone don't actually offer any protection.

Really? It seems much quieter. Can you explain?

It's quieter because it produces opposing soundwaves or something to that effect, essentially canceling out the loud noises. A google search can explain it better than I can. But those sound waves are still hitting your ears.

Very curious how this works. If the waves are cancelled, how are they reaching the ear?

From what I understand, they are reaching the ear, but there is noise being applied on the opposite spectrum to cancel the noise out? Think of sound as a wave in a graph, it goes up and down. From my understanding active noise cancelling is just seeing where that graph is and playing(?) A sound the opposite of that exact wave lenght and therefore canceling it out? So you don't hear it . I may be completely off here this is just what was explained to me and until this second I took it as well okay that's how that works.
