Im not a verified reviewer and get nothing for this, so this is an honest review. I have had Keens for years but not the Ravine but didnt like it. For the TLDR readers out there: they sound amazing, ANC and touch controls suck majorly right now, the build and comfort are perfect, and I would easily recommend them. Now I can type on keyboard and listen same time. so you have to jam the foot in and we all know that is just not pleasant for anyone. They hold abput 10 ml of diamonds which equals about 5 packs of the standard DMC diamonds. My toes were not close to the front of the sandal due to the tightness of the straps. Would buy again Top marks :) I really dont like that the alarm clock does not let you set it for different days of the week, and repeat each morning.
