I’ve combined these headphones with earplugs for a plane trip. Engine roar overpowers the sound for bone conducting headphones the same way it does for earbuds or headphones that don’t isolate. You might still need to crank the volume up, though. Planes are loud. No issue of other people overhearing it at that point though.
Passive aggressive ‘All your veggies are actually fruits’ energy here. I love it :)
This has been a regular debate in my household and I’m with you on this.
