Custom Moulded Earplugs for the well-being of your employees

Cotral Lab's custom moulded earplugs outperform all other devices on the market. They enable interpersonal communication and are comfortable, convenient and cost-effective.

Custom Moulded Earplug 3D scanning process

How do we create your custom ear plug?

Our manufacturing process works as follows:

  • We take an impression, or mould, of the ear canals of every employee
  • The mould is 3D scanned to create a computerised image
  • The computerised image is then modelled into the smallest, lightest and most comfortable ear plug ever made

This comprehensive process ensures that each hearing protection device fits perfectly, with 100-micron precision (the width of a strand of hair). They are so comfortable that they can be worn all day.

Be Protected, not isolated

The moulded ear plug is personalised for each employee thanks to our filter selection process

SAPAN® considers the noise level, level of perception, and the unique requirements of each employee.

Qeos offers two ranges of filters, each providing a different level of attenuation.
