Very comfortable armband, rather quiet with good support, I hardly feel it when I run. Moreover, S4 can be inserted there with the flip cover of the folded shell side without forcing (by cons, impossible to manipulate the volume +/- buttons with the flip cover). The opening for the headphone jack is handy. After it is a cuff, do not think strum easily on your smartphone while you run: start / stop your running software yes but no more (visibility problem, access to the screen that asks it to pivot toward your head and again ...). By bringing it to the forearm, it would be possible, but in this position, it is rather embarrassing. Now we have to see how it will age over time: after ten outputs, it has not moved. In short, to recommend as it has done its job.
