I cannot tell you how many different headphones, earmuffs, earplugs and etc. Also, the snaps come undone super easy and frequently. I ordered size 9 regular. Its also small and portable enough to throw in the car for use in the field. I wanted to love these headphones, decent fit, "just enough" battery life (for the gym), somewhat comfortable and decent sound (I also use a set of BeatsX and Bose Soundsport original). My ears got a little warm after a couple hours, but a short break fixed that. They fit and had a soft bottom, but the strap between the toes has taking several days to get use to my feet have been sore for over a week. I have wide feet and finding shoes?even slippers?can be frustrating. Overall I?m very pleased & hope this helps! The back bar is shorter that the front so make sure you have them in the correct area
