COTRAL Sound

CHARACTERISTICS

This solution combines a COTRAL Prima 3D hearing protection with a communication kit which can be fitted to a walkie-talkie or telephone equipped with a free hand connection.

EC certified, this custom hearing protection* is manufactured from Crylit (a hard material specially designed for digital manufacture of the protections) based on the 3-dimensional modelling of the impressions taken by the Prevention Technician.

COTRAL Sound is easy to insert, ergonomic (it does not move, even under difficult conditions) and the technical qualifies of the differential electret microphone provide it with an exceptional sound quality; interference is markedly reduced in order to guarantee maximum communication comfort.

It is also equipped with a large manual voice control with an attachment clip, allowing easy and completely free communication.

Options available with COTRAL Sound:

Service life of the protections: 4 years
Guarantee against manufacturing faults: 4 years
