If you ever had a pair of these sandals before i. Photo - charges at 400mA. My favourite feature is the gain control and mute button right on the microphone. 40 minutes to an hour round trip. (Pooda was a questionable but otherwise interesting). Adjusted easily and they feel good on the feet. It has lots of features to control features of the speaker. I finally found out that the smallest size in this pack fits my ear well enough while no other brand can offer a size that does. Other than that, it looks great and can hold a lot of my winter jackets. These are adorable and comfortable!
