Ears are like people – each one is unique and different. That’s why SmartFit is so user-friendly in design. As the only reusable earplugs with Conforming Material Technology, SmartFit uses the wearer’s body heat to adapt precisely to the shape of the ear canal, ensuring a comfortable, personalized fit in the ear. With the removable band system and the HearPack storage case, it is the smart solution for today’s diverse workplaces. BGIA recommendations S (signal hearing in track superstructure possible), V (signal hearing in road traffic possible), and W (criteria for 'general warning signal hearing', 'informative sounds', and 'speech intelligibility' met). Versatile for use in all situations, especially where hearing warning signals and ambient sounds is crucial.
