Seems pointless and inconvenient for me as they usually seem to be poor quality, and can you really listen to music in the shower, and are you showering long enough to benefit from it?
Or do you own one and use for a different purpose, like swimming or Kayaking?
I’m not wrong. I’m stating my opinion. If I am wrong in stating my opinion than you are wrong as well for stating your opinion. I have a pair of open headphones, Audio Technica R70X. They still allow music to escape just as bad as it would be for a Bluetooth speaker to be playing at low volume. Perhaps Samsung Buds Pro 2 could work, but why would you want to seal yourself away from nature that much if you’re out hiking? Bluetooth speaker has been an appropriate choice in my experience.
If you’re in nature to enjoy nature, leave your music at home. No one wants to hear it but you.
And open ear headphones are different from open headphones. Open ear headphones are basically ear buds that don’t go into your ear canal, but direct music into it.
