Im sending this pair back and sadly looking at other brands. 5 in these and they fit wonderfully. Son clair et net. The only thing I wish is that the bins were deeper/bigger. Although slightly tight when I got them, they did not cause any skin trauma. Now, the negatives. Now that I have gotten much older, I am looking for a simple program to restore some lost strength. They dont have a lot of base. However, the audio quality does change a lot with the open v/s closed tips. likely in more places that were not appropriate for a flip flop, and thus I bought them again last summer (July).
