Highly recommended for short distances (2m)

Delivery, scale and unit:
Delivery by Amazon as most went very well. Did it even get one day before the planned delivery!
Scope of delivery just like in the statement made! -> Yay
The unit itself is very good and robust built. Very small, fits in any case in your pocket and the operation is limited to switching on and off (press and hold button until LED lights up blue or goes out) and the pairing with another device. (Button until the LED flashes red) -> This is for me one of the greatest features. Have this equipment unpacked and knew me even without operating instructions immediately. For all others there is also a very nice Pictorial Description of these processes.

Conclusion:
The plan was to use this device for the transmission of movie audio. Unfortunately, however, the removal of my TV to the boxes behind the bed (about 5 feet) a little too big and, this results in very long delays of the signal. Non time-critical applications such as playing music runs on this distance also very irregular. From time to time for about 4 seconds. represented nothing and then speak forwarded the signal through the Bluetooth receiver.

However, it is super for example train. I always hated it, directly connect my headphones on a laptop, because I had to get away quickly in some situations, and then I usually forget that there still were the headphones connected.
Even on the go with a mobile phone, I find it great!
I can finally make Selfies while listening to music ^^

Since the range in the description is something of an exaggeration, there is of me only 3 stars.
