Fits somehow not quite

Now I was curious about these in-ears, which should be particularly suitable for sporting activities.

Somehow my ears do not seem so to be quite compatible with the brackets, because really I'm not getting laid you in-ears unfortunately. As I stop my glasses in sports, would actually be enough space on the ear to attach the inears, but somehow I did not get it, that they'll actually stick with movements on the spot.

If you ever have a good fit, so the sound is great. But if they stop moving at the ear, the music suddenly seems tinny or distorted.

For sports so I will use it rather less. But when they look cool, I'll just use to make phone calls or to places where you want to listen to music without big move (train rides, waiting times, etc.)
