You don't absorb it, you block it, which is not the same. Stiffness
and a bit of mass does the job.

Solid concrete headphones perhaps?
Stiffness is all that is needed
And the "bit of mass" ?
No, they were invented because someone could. They then fulfilled a
male need for gadgets. I haven't done the data mining, but I'm willing
to bet that a good closed back or ear bud (Etymotic et al) provides as
good if not better LF isolation than a NC.
As I already said many posts ago!
However the NC type *may* be lighter than closed back types with good
insulation.
As always you pay your money and you make your own choice.
