Operation is simple and straightforward.
By press (7 sec.) Of the Power - Button / Play and Breakfast, as one calls the three buttons so that connection to the cell phone was found quickly.
The coupling is retained and you can always quickly contact it again.
Had the cap for one day under continuous load.
The cap keeps you warm in really incredibly strong wind and freezing temperatures.
For that I would like to assign alone 5 stars.
The sound is top notch.
It has a clear sound and the mussels / speakers are large enough.
The charging time is quite short and straightforward thanks to Micro-USB.
But the reason why the cap is no longer remains in my possession that, as I walked through the city or through the countryside without any building or a human encounter, constantly somehow the reception was disturbed.
The songs were all over very ticked.
I have made the new coupling and after few meters again the same.
Have besides my headset is connected and everything was good.
So it is my opinion at the reception.
That is why I must, unfortunately, be separated from the cap because it is my demands justice.
Even me is the runtime bit too little,
However, what could more than 3 hours are sufficient for many as well.
I mean otherwise have purely a larger battery and that would affect the wearing comfort.
So my conclusion.
I recommend it further, since the cap is really a great idea.
To me she is not enough unfortunately.
Therefore, I send them back.
