I got these earplugs to help with the noise in my welding class. I love the little carry case that fits on your keychain, The earpugs were comfortable and I liked them. Problem is that i lost one of them the first time i wore them. If they had a lanyard on them it would be awesome. OH well I guess i need to purchase them again. I have purchased several items from this manufacturer. I have been very pleased with each purchase. This is the only purchase where i would give advice for future customer satisfaction. Include a lanyard that is removable so ensure that the plugs do not inadvertenly get lost
