I should of gotten an 8. Excellent product and easy to use with the hitch mount rack. Earbuds can be used independently and theres no interruption of you decide to put one bud away while using the other. i would absolutely buy again ! I bought my husband these for his Beats3 headphones. So I decided to go with the xxl simply because the slip was longer. Super light weight. Try it. The non-slip bottom is really effective, much more so than the normal Crocs. They are so comfortable, you dont even know you are wearing them.
