Due to distances involved though, any sound would be delayed similar to a lightning strike on earth, but much worse because there is no real medium for the sound waves to propagate through but rather the atmos and molecules themselves moving through mostly empty space.

Also, at best, you might hear a thud rather than an explosion due to you being contained in a sealed, pressurised container (aka a ship). And even then, it'd more likely be from solid debri rather than from the very sparse (comparatively) atoms and molecules of an explosion.
