Soft comfortable fit
SparkPlugs® earplugs are made of extra-soft, extra light foam. Their tapered shape fits easily in the ear canal, and seals gently and snugly without pressure. They’re so comfortable you’ll forget you’re wearing earplugs.
Independently tested: NRR 33
SparkPlugs® earplugs offer a high NRR 33, making them suitable for most noisy environments. So, while they look like fun, they provide serious protection.
Metal detectable Version
SparkPlugs® also come in a metal detectable version which has a new metal detectable cord. The bright blue color is perfect for food processing applications. The enclosed metal ball bearing eliminates any exposed metal. The ball bearing and cord are in separate holes so that the earplugs remain detectable even if the cord is removed. The earplugs are corded to prevent earplug loss.
