I currently have it filled with 21 different jars and tins - I have included a picture for reference. Fits to size My earbuds was still playing music in the case. The speakers are toward the ear canal and heard by anyone else. Thankfully I receive barely any calls on my personal phone while at work, so it isnt an issue for me. If I wasnt so busy I would return the replacement too. At first, I was very disappointed with the static noise I heard through the earbuds when no music was playing. Theres still room for shoes too. I just didnt like the heel strap personally. I cant comment on the longevity of these slippers as Ive only been wearing them for a few weeks but for fit and comfort they are even better.
