They are really cute. I?m always hesitant about ?silky? type things as a curvy girl but these had just a hint of stretch and fit like a dream! I do not feel any discomfort or pain inside my ears. 5, decided to get an 8 just in case. This are about 3x as thick and about half an inch longer, but manage to stay on just fine. Shes not as fussy as I am about the "fi" in hi-fi, and thought they were pretty good. I added alittle peice of rubber around the bar and the clamp fot perfectly after that . Now the bad part: microphone quality is terrible. Ive been wearing clarks flipflops for forever. My 3 year old is on the edge of an 8 and 9 in sneakers and they fit him perfectly!
