I've found the Nonoise Work earplugs to be more comfortable while at the same time providing more hearing protection
I'd purchased the Nonoise Work earplugs and High Fidelity Earplugs for a comparison.  After approximately 20 hours of motorcycle riding, I've found the Nonoise Work earplugs to be more comfortable while at the same time providing more hearing protection.  What I've also noticed is the Nonoise are more durable, fit more easily into the ear canal.  While both products are very good, the Nonoise Work is the superior product.
