The volume wheel seems a more flimsy part, so I worry about durability/longevity. They rarely fall out my ear and its typically because I didnt have them in right or they get caught in something. Very quiet and smooth riding. Pic of tear uploaded. True to picture. The GREAT! I could have spent big bucks on a top brand, but I didnt. That was a big mistake. Ive bought and used three before this recent purchase, and as I am typing this, I am still using the 3+ year old version that despite reviews about durability and battery life is still kicking. These gorgeous slippers are very pretty and seem to be very well made.
