I normally wear a size 7 and I had to send them back and get an 8. The control / battery box is bulkier than expected and the length of cable between it and the headphones themselves is too short for comfortable manipulation. A nice little holder for Q-tips. They are also pretty stretchy which makes them even more comfortable I really recommend these! Wireless charging still works even the with case on the Airpods Pro. The Boltunes offer a good dose of the sound quality, look smart and offer excellent value. Easy to take on and off of bike for charging. A slight learning curve, but definitely a keeper once get the hang of them. The color is pretty and my 10 year old daughter is very happy with them. their wall fasteners did not work for me buy your own from hardware store
