UNA TOTAL PORQUERIA!No recomiendo a nadie comprar este produncto! Gastar 26€ en esta basura... No es cierto que reduce 26 decibelios los ruidos!Además, una vez utilizada la masilla, no se puede hacer devolución y pierdes el dinero.REPITO, UNA TOTAL PORQUERIA!!

Leichte Anwendung, die Menge ist genug für 4-5 Ohrstöpsel

These are awful...they cracked and fell to pieces and never fit right from the day I bought them.Even worse, you can't send back for refund after you've moulded and tried them.I felt genuinely ripped off with this purchase...buyers Bewarned!!!

Product as described and just what I needed.

I hate putting down a product, but this just doesn't work - the material is too hard, and even if you do a virtually perfect molding, when putting them back it, they do not vaccum / seal your ear channe. Wild guess is that you can at most achieve 10-15db NRR with this, but the lab value is absolutely impossible to reproduce in reality. I'm sure that for the lab test, they molded it into the plastic ear, and tested. When the correct protocol should have been to mold it, take it out, put it back in. I'm going back to oldschool earplugs, who have a foam memory, so they really grow in the ear, and seal it tight. Furthermore you find earplugs with 32-36db NRR. Sorry for the entrepreneurs who developed this product, but the concept simply doesn't work.
