Sometimes these earbuds slip out of my ear, i dont know if there to big or my ear is maybe oily. M4 and M5 buttons on the side are also slightly smaller for less accidental presses. It gets caught on EVERYTHING. I could barely get my foot into the slipper and my toe was right at the end. The top screw is a little difficult to screw in because there isnt much clearance, but I made it work. Super comfortable for long walks to class. Walking on clouds every step, every day, all day, all summer long. Even come with a separate in line mic lead and carry pouch. Obviously the ends of the rod cannot hold super heavy clothes but t works for my daughter. Shame on them/him/her misleading people and selling "package shipping" material as shoes at the price of over $32.
