The worst earphones ever

First, I am pleased that we something "given" get, but the portions are really useless.

I would say, I have normal ears, but these earbuds fit at all with me. If I would therefore still do sports, they hold not guaranteed.
A small "Kopfschüttel attempt" has this confirmed.
This attempt to make the way automatically as soon as you hear the sound ...

For my partner the same, even with her the parts do not fit into the ear.

I do not even know to some extent, for what could really use the parts ...
