+ Comfortable to wear, even over long time no pressure and Schwitzgefühl
+ Sound neat, especially when, as in my case, to music going (Concert Photography)
+ Speech perception in noisy and quiet environments still quite possible.
They need not necessarily take out, if, for example during concert times will entertain the smoke outside itself.
+/- White transparent color is pleasantly unobtrusive, but also tends to "Verschmuddeln"
And "secret" because it took a long time to find this product.
At first I had - like many others in the circle of friends - only discovered in hearing protection stores also manufactured by Alpine "complete".
Here the same slat inserts but are offered with 3 different filters as a set.
The filter will then have different attenuation values / strengths.
Disadvantage: the set is about 25 EUR
For my application were regularly only "moderate" filter in use, they meet the filtering Party Plugs.
Thus, for me perfectly because much cheaper.
Actually, hearing protection should be any a duty when it comes to visits from loud concerts or parties.
And since these plugs the "cheap plastic disposable plugs" to superior lengths is the price
I use them as a hobby craftsmen at the occasional loud work.
But you have to be careful, to my knowledge, they have been approved as hearing protection because of for "good sound" optimized damping curve not in terms of occupational safety (if there over the years nothing has changed, but I suspect not even).
