My wife and I opted for the Pluggies because they are made for children's ears, and do not foreclose entirely.
We have so far, although only once test, but are absolutely convinced.
The test took place on a weekend at the Nürburgring, as there took place a long distance race. At first, our son stopped her ears. There he was so clearly too loud. With the Pluggies it was for him in order. And above all, he has nevertheless understood what we are saying, without us having to excessively talk loudly. An indication that the filter works.
The onset of Pluggies is also more than simple and well described in the manual. Whether the enclosed applicator is really needed is sometimes an open question.
From us is an absolute buy recommendation !!
