The need for rapid communication is growing all the time. As technology improves there is also a growing demand to be able to reach each other at any time, whether at work or in our free time. The mobile phone has become a natural part of our daily life. It is a tool for various forms of communication. We use our mobiles everywhere today: in the car, on the bus, in shops, on the street, etc. At work, many of us are forced to spend time in environments that can be harmful to our hearing. But we must not risk our health just because we need to hear a mobile! We therefore felt it was vital that we should develop our hearing protectors so that they can be used with mobile phones.
