Not "Plug and Play", but ....

Initially, I was disappointed and the part was almost in the return package. But I also do not give up so quickly.

Now time to the facts.

You should unpack the part and first hanging definitely several hours to the charging cable.

Then bring the receiver into pairing mode. Then keep the button held down to the part until the blue and red LED flash alternately. Now the coupling is and the blue LED flashes slowly.

For this one should say that only devices can be coupled, using the common code as "0000" or "1234" and so on.

The observer immediately notices that a slight background noise is heard. That does not exist in the BT connection between my mobile phone and headset. So I assume that this is due to the part.

But it's not perceive with normal hearing. The audio quality when watching TV, listening to music or gaming, I find totally OK
One should depend on the part of a long phone cable and store somewhere above. This optimizes the range significantly.

If you are traveling while listening to music in the home, it can happen that the signal only arrives choppy and no longer is better if you come back in the coverage area. Then help a power cycle of the recipient. But that does not always come before. In most cases, the combination of self-normalized. What the related, I did not even get out.

That was it but also already.
So, patience is rewarded with functionality and I get the part because of background noise and gelegendlichen problems disconnect a buy recommendation.
