Earplugs are essential for travel because they help block out the constant background noise you encounter during your journey. Whether you're on an airplane, train, or bus, the sounds of engines, conversations, or other passengers can be distracting and make it hard to relax or focus. Earplugs reduce these noises, allowing you to enjoy peace, sleep better, or concentrate on reading or work. They can also protect your ears from the potential damage caused by prolonged exposure to high-volume sounds, like those from loud machinery or engines.
