These are okay. The concept is great, and they are nice headphones. But neither set of the boots fit my ears. I don't have big ears, maybe my ears are too small for these. They give me some serious pain in the cartilage of my outer ear, and I am constantly having to readjust them during my workout because they slip so much and block almost zero outside noise (which is frustrating and causes additional pain to my ear). I honestly feel the only thing keeping them attached to my head is the bondi band I wear over my ears. I wanted to like these so bad. Maybe I just need over ear cans for my workouts
