To me, that is the most important thing and these just don't pass the test.

These things provide true freedom and are actually quite comfortable.

The only good things I can say about these earbuds are the long battery duration and the fact that they didn't hurt or feel uncomfortable after long periods of time

The charging case is also about 30% smaller that the E19s, so it does have a lot of good things going for it

Another great thing is the sound quality while talking on the phone with someone.

so there's a bit of background noice (which is probably a good thing to keep you safe walking in public).

My favorite thing about these ear buds is that the battery life is not exaggerated.
