Adjustable, custom made hearing protector

A lot of attention is paid to the attenuation curves featured on the packaging or the instruction leaflet when making a good choice of a proper hearing protector. Vital for the performance efficiency is that this factor is dependent on the frequency of wearing and the attenuation when worn. A good fit is very important for wearer comfort and the frequency of wearing and it is for these reasons that the Variphone® hearing protector is fully custom made.

The unique 2-canal design of the Variphone® allows tuning of the attenuation quality controls fast and efficiently including regular check ups. The adjustable valve allows the attenuation to be set to reduce the noise load to a safe level.

The fine tuning of the attenuation, with accuracy of 1 dB results in retaining the best ability to communicate.

Process flow

A team of technicians are available to arrange visits at a location convenient for you. After an ear inspection an ear impression can be made which is sent to our laboratories for the manufacturing of an individual Variphone® hearing protector. A second visit by a technician is necessary for the fitting procedure and fulfilling the standard quality controls.

Before the Variphone® can be used it will be tested on functionality (leaktight test) followed by a very precise adjustment for a calibrated amount of attenuation. These quality controls, which will take only a few minutes per person, are part of the standard procedure and will be done on location. 


Every Variphone® hearing protector will be delivered in a durable storage pouch together with a detailed instruction leaflet, cleaning cloth and earwax remover.
