I rated these as fitting a bit too large, but that’s because I had to buy the next whole size up. I had only one issue - one of the two LOCKS wouldn’t seat. I am returning this product. I like the fact that I discovered it and using wire now when I just want to sit and enjoy music or play something. The stickers which are supposed to hold the case on DONT WORK! That mixed with these headphones, makes for a damn nice combo. At first they were super comfortable. They fit perfect and look really great on! Good・音がクリア・デザインが可愛いBad・最大音量小さい（外出するとあまり聞こえない）・音漏れするので電車利用は難しいかと・重い I’ve washed these in the washing machine and that helps clean the fluffy strap on top decently well, but the part that touches the bottom of your feet always look dirty no matter how much care you put into washing them.
