Thats what destroyed mine. Purposefully looked for paper or cotton. Center 8. At the beginning I couldnt find them comfortable but I changed the size of the little top that goes in the ear and I solved the problem of falling off the ear! Pedí mi reembolso y regreso el material, es una pena. I want to wear it all the time. The jack is straight and the cord isnt too short or long. I was afraid theyd gape open, but they fit perfectly. They got to 93% and not past. Id never even noticed and assumed it was random until I checked to respond to the question.
