These would be good for short slightly thick feet. It has USB-C and SD card slot. The gasket has the required magnets already fitted, so you are good to go straight from the box. I have tried the lanyard and that sucks. It really helps my tires feet on the cement floor we have. Aside from a few exceptions, this is the pinnacle of IEMs guys. Was really excited to receive this, but it turns out the product isn?t actually black and has a rose gold/sparkly finish. I use them with heat shrink tubing to make the joints perfectly robust and strong. The leather is soft yet supportive, and they wear well. It was a size 8 and fit perfectly.
