The Elvex Blue disposable foam ear plugs have been redesigned and retooled. The most obvious change involves the shape, which is more tapered, and the foam has become softer. As a result of the new shape, this generation of ear plugs is easier to insert correctly, which has resulted in a significant improvement in the Noise Reduction Rating to 32 dB. The highly visibile blue color also makes it easier to monitor compliance. Additional benefits of the Elvex Blue ear plug include a unique ergonomic shape, slower expansion for easier insertion and better user acceptance.
