Have already tested out the waterproof and in my opinion Keen does very well with their water protection. That being said another positive of the earbuds is the fact that the charging times for the buds themselves is really good on average they reach the full charge and about 90 minutes which again is as advertised so good stuff there as well. möchte man noch 30 % mehr . stable comfortable fit, doesnt make me feel hotter even in 85ish temps with high humidity, pouches for energy gel, sweat mop, etc. Wanted these to work, so I used them and can not now return them. High echo and a humming sound. The quality has gone out the window on this model. The main reason I love these shoes so much is I have a high arch and they have suchgreat arch support. Die Leder Polster haben Innen eine Art Plastik Verstärkung, die ziemlich locker drin ist, wodurch diese noch schwerer zum Aufziehen sind. I purchased these to listen to television while using a noisy exercise bike.
