Not realizing it came with a set of feet already, I ordered a set of square, clear feet to protect it from moisture that it might pick up from the countertop in the event of a spill, and they do a very nice job. Un equipo barato para funciones básicas. They have the best overall noise cancelling, comfort, and sound quality. Classic Ordered a 13 and fits proper. It?s sturdy, and I like the angled connector for the aux connection. Why tell me? Why interupt my song for that? Annoying, but not deal-breaking. I hope my original review, as well as this update has helped! - The battery also shows the number instead of a set of LEDs, which is convenient. They stay on my feet, are comfortable to wear all day, and are almost indestructible.
