The health of our ears

After 300,000km motorcycle one does not give the number of Db that accumulates but it is significant especially with a somewhat noisy helmet!
I put those same protections systematically to 20 terminals, comfort is very good, no irritation (though not recommended to those who make the atrial eczema), or very marked discomfort after long journeys.
it washes 5 seconds with water and soap. No big difference between the two "filters", I use all the time and most filter that does not interfere with driving, you always hear the important traffic noise but the whistling of the helmets are blocked. Perfect! The small case is convenient because it is easy to lose (it bounces falling down!)
I will pass me more and advises such products to those who are exposed to continuous noise (damage caused by the decibels are cumulative throughout our lives) and want to avoid irreversible damage past 5O years.
24 For no hesitation for me and after 2 years of use I'm not income

>>> Update: I just re-order a new game because mine after a few years (> 3 years) of loyal service and begin to tire notement relax at the introduction of the yellow or green filters no longer hold good.
I note with pleasure the evolution of the packaging makes it easier to store different elements and bonuses offered in addition to a plug for loss, nothing to say for the price it is what is done best, if not it must turn to the bespoke prothesiste in the audio.
