When I first put them on, I thought "oh no, they dont fit". I can’t comment on battery life since they are still rocking. Cozy, warm, and comfortable. I love all FitFlop sandals, However, I docked it a star because though everyone talks about what cars the rack can fit on, not anywhere is mentioned (or that I could find) what bike frame types. 5mm Y-Splitter for the audio and microphone. I use these daily now. I tried it once for running and its horrible feeling. Ich kam in meinem Test auf eine Laufzeit von 38 Stunden im Active Noise Cancelling Modus und ohne auf eine Laufzeit von 57 Stunden. - I need shoes that can be washed and used in aseptic clinical environments.
