ear plugs

Qeos Custom Earplugs from Cotral Lab are custom fitted for each worker, offering comfort while allowing workers to communicate without having to remove the earplugs. The Qeos devices come with seven different filters providing real attenuation from 8 to 33 decibels. The devices can be used by workers even if they change jobs or are positioned at work stations with varying noise levels, due to the flexibility of exchangeable filters. The steps in the manufacturing process for these earplugs include taking the mould of both outer ears, manufacturing the moulds through 3D printing and implementing the proper filter for each worker. This comprehensive process ensures that each custom earplug fits perfectly, with 100-micron precision (the width of a strand of hair). They are so comfortable that they can be worn all day, says Cotral Lab. Qeos Custom Earplugs are backed by a six-year warranty that covers material, comfort and attenuation. Devices also include cleaning kits to ensure both cleanliness and effectiveness of the earplugs.
