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.
