Was real easy to install Only now at the end of summer, close inspection will review a tiny bit of wear/fading of shark print on toe tips. It’s a piece of cheap crapConnected to my phone after fully charging an it worked for about 2 min and quit so I turned it off and repaired several times with the same result Amazon why do you even sell this crap Im so impressed with these! Took a bit to figure out the pause/play/Fast forward but easy to figure out. The installation went very smooth and easy. Given the price and that these are hospital style shoes I would have anticipated at least a year if wear from these shoes. I love KEEN shoes. The sound quality is on par with other headphone in this price range. There is a very thin rubber-like cushion on the inside of the hook that wraps all the way around where the hook meets the cupboard so I didnt have to cushion these hooks to protect the furniture.
