What really gets me about these expensive gadget helmets is that helmets are fundamentally a consumable good. They can only take so many bangs and bumps, so much sweat, so much all that before they start to wear out. The miscellaneous wear and tear on them. Getting dropped on the ground, banged against things, taken apart and washed and put back together. And for most helmets, once the foam wears out, that's it. They no longer are fit to purpose as a helmet and should be replaced.
Back when I rode a motorcycle -- which was commuting to work for the better part of 2 decades -- I always got the most affordable, comfortable DOT-labeled helmet I could find. Any extra gadgets had to be aftermarket addons that could be portable. Because things like headphones, for me, always lasted 2-3 times as long as the helmet.
MAYBE a really high-end helmet has a longer service life. But I am skeptical even a really fancy one worn by a commuter using it near-daily would last more than maybe 4 or 5 years. They're going to have lifetimes like smartphones, for sure. Which means these gadget helms sure do have a high subscription fee to use.
