Upper class quality!

In short: Pro -
1) About Zigarettenazüner rechargable
2) Long Time
3) Excellent voice quality when making calls.
4) Good noise isolation from the outside
5) Foldable
6) large control buttons
7) überragdende Bass ability
8 Lightweight
9) Fast logging in

Cons:
The keys are indeed grolß but Gewöhnungsbewdürftig because blind orientation is difficult.

I would still like to see an external Micro which is plugged.
Even an "active noise canceling" feature would be chic, like also for NEN 50 more.
