They are handy when sleeping in a noisy campgrund or sharing a room with a snorer.
I always listen to the motor when I'm gearing up to leave. I've found though that on the road, with earplugs in it amplifies the other senses. You can -feel- when the bike is performing, or handling differently than is normal. At least, in my experience.
