Nothing to say, these earplugs are perfect ... I could go to concerts or disco, although situated near the speakers my ears have not suffered (although I have a problem with one ear following a concert precisely). The carrying case is a little more. I can also easily follow conversations and not have to yell to be heard (though the neighbor hears worse than you ...). I particularly enjoyed a concert where percussions were the majority, I could see perfectly instruments. By removing the caps, there are sounds that dominate and not necessarily the best (maybe the fault to the acoustics of the room ...) ...
By cons, it was necessary for me cut (and it is not obvious, risk of error ...) the flexible part because the plug did not fit properly in the ear, may have irritated ... perhaps it is because my ears are not big! Another negative point, the price, but I think it pays for itself over the years.
These are the best ear plugs that I know already have another product of the Alpine range, to ensure the SleepSoft nights in youth hostels, night train, etc, having the safe sleep (even with the snoring neighborhood!).
