I have this cushion ordered as protection for my iPhone in ear headphones, as I use this for sport and a cushion is easier on the ears. This 24er pack is really great. The cushions can be very good pull on the ear plugs, and do not break, are very elastic. With 24 pieces you can renew only once for a while from time to time, which I think is nice hygienic when using the headphones during sports. Great price, good quality, delivery 1 day awesome !!!!
