MaxLite earplugs are ideal for long-term users and those with smaller ear canals. The low pressure foam earplugs offer long-term user comfort not found in other pre-shaped foam earplugs. The non-irritating, non-allergenic self-adjusting foam recovers to fit virtually any ear canal. MaxLite is also ideal for that portion of the population with smaller ear canals.
