Shure != Bose, but also I don’t think you can shower in the Shure IEMs. Maybe with a case or something on them.
I use Aftershokz for something like shower listening but those are the opposite of your problem - they’re bone conduction so they do not block any sound.
Also to be clear - my earbuds are wireless in that they just clip to my belt loop with the Bluetooth receiver. So I can have them out of the way but easily available.
It’s less idiocy and more laziness. Any amount of inconvenience is too much for a lot of humans, unfortunately.
