Since qques years one becomes aware of the danger of "noise" ubiquitous or too hard for our hearing. And that's good !! The problem is that between knowledge and action, there is still a bcp not hesitate to cross. But I believe it. This is like the helmet for skiing or cycling. Just as qque watch with personality and launches the "mode" so that it becomes IN, and it enters the customs. If ever you are interested in any case, be aware that these are not bad. Their advantage: comes with a small box that easily fits in your pocket for storage. They are reusable. Washable (slightly soapy warm water and it's good). And above all they are discreet !! The sound is lessened without removing the right to the concert. Lets have a conversation if necessary. Prevention is better than cure. Porter occasionally these ear protection is better than having to bring to life an appliance or suffer tinnitus! Think about it. Health is priceless.
