I mostly use the golden filter.
The first test was at the Sonisphere Festival 2010 in Milovice near Prague.
Music Safe Pro VS METALLICA, MEGADETH, ANTHRAX and SLAYER
with the smaller bands I had almost 12 hours in the ears
still comfortable, after a short time you can forget that it ever has in it.
the next day: AC / DC in Dresden
The sound remains in good condition and you can hear the next day still 1A
(It's really amazing how many go without hearing protection because there ... doof without =)
AC / DC, it was only one problem ... the fans were already alone saulaut * g *
the price is OK, the storage helpful ...
(Where they also could spendieren ne cord)
the biggest battle is the parts before yet: WACKEN
(Just think about it if you did not go ... you hear not right on the first evening and take the next flutes)
If you have the wherewithal wirlich, let you establish that.
The offer some of the hearing aids or similar . Sale
Here an accurate ear impression is made and achieved the desired damping.
Although some costs but if you often go to concerts it pays 100%
Otherwise, I recommend the Alpine parts
the yellow plastic and other things cheaper stuff are not fit for work but for music concerts
