Run a little large and I had to size down. OUTSTANDING! The charging case sits comfortably inside. I liked this speaker a lot when I first received it, however I only used it about eight times before I started having trouble pairing it with devices. fit. Excellent for all levels of fitness from beginners all the way to elite level athletes. The next day, my space bar, and then my Prinyt Screen key as well. Got a pair for every member of the family. Most phone holders are so difficult to remove the phone that I didnt bother. Im glad I ordered 2 sizes extra or it would not have fit.
