At some point I came across this product which is priced very pleasant not only, but also a lot of good reviews and has at the same time. So I did not hesitate and ordered it to me immediately:
In a small, rather inconspicuous packaging is the Bluetooth audio receiver including micro USB cable for charging and a short AUX-cable to connect the receiver just to the AUX port on the terminal. More so you do not need.
For me the battery was unfortunately totally empty. With a conventional 5 Volt USB power adapter can charge the good thing: It will turn red with a tiny LED when Loading and blue when it is fully charged. How long does the loading process, I unfortunately do not know, since he hung up at night in the socket.
So connected the next day with the AUX cable to my surround system and iPhone started the search. It took about ten seconds until they have found each other and connected. Very exemplary.
So now I was able to select my music and enjoy without any interruption, delay, etc. - and of the highest quality, as I sometimes did not even have a AUX connection. Nothing rustles, hums or sounds tinny.
Also, the battery lasts pretty long. As I know, unfortunately, no precise figures, but in theory it should always be the same, because you just do not regulate volume on the receiver.
Conclusion:
I'm pretty happy that I finally bought myself yet so a recipient with whom I just do not have to get up every time to switch the music. Without a doubt, unconditionally and so full five stars from me.
