Bin mit den Schuhen sehr zufrieden. Finis solution? rub it with alcohol and brush and soap and you name it. I recommend this product to people that are exigent and want to pay a fair price to have a good listen to music. But you have to put it in the perfect spot in your ear otherwise you cant hear out of either one. I LOVE THIS DRESS! They feel secure in my ears, which is very Important. La troisième paire me vient dici et je suis très satisfaite on a limpression de marcher sur un nuage. Not recommended for bench or anything that requires. Which mine did not have. I’ve used these for a few times only.
