So beware if you try to order this size. When they came in I rushed home to try them on & they fit perfectly! Arrived way earlier than expect, even by Pre-covid standards. 5 shoe, I got the size 9 and they fit perfect. 1kg but the hanger will support bikes up to 18kg. I have slightly smaller ears and other earbuds caused some pain after more than 30 minutes of use. But this is unacceptable for the price. In fact it works better because being hooked over your ear lets you smack on the AirPods more aggressively, which Ive found triggers Siri more reliably. I guess I can live without a middle-click for now. I also like how it holds all four corners of the phone.
