I was kicking myself after I ordered these thinking I should have bought mules instead, but these are perfect. It was posted that the shoe fits well, order your regular size. I needed a travel P. LOVE. Honestly, being somewhat of an audiophile myself. so i ordered an 11 and they are perfect! Its easy to feel a sense of "buyers remorse" after purchasing a headphone like this. The only issue is if you try to move the unit with clothes on it. and love them. So as skeptical as I was I bought these replacement and they sound pretty darn good for the price.
