You have to really long on the button on the receiver until the LED really white / blue flashes.
I kept thinking the blue flashing would be the detection mode.
Really well the distinction is white / blue and blue not.
Having solved the problems with the recognition I am fully satisfied with the headphones.
(Uses 1 week in train and not empty> 6 hours) Noise-free uninterrupted music with an absolutely awesome long term
And then I have still the audio cable, which also does not have any Bluetooth headset.
I had a wireless headphones from Sony (not entirely cheap) but the transmission quality and mainly denominated disturbers were absolutely disappointing.
The comfort is very comfortable (nice firmly around the bubbling around me hide in the train, but not too tightly) on my large skull
Incidentally, I also found a way to prevent my Android smartphone that automatically and unintentionally selected the headphones at pressure of handset buttons phone numbers. Just when you connect to the Buetooth Settings Hold longer the SHB9100 Tab and then select only "Connecting to media audio".
Then the headset functions are disabled (I also wanted a headset)
