bluetooth headphone can't pair I have LG e975 , android 4.1.2 and a bluetooth stereo headphone Pyle PHBT5  which supports A2DP.

The problem is that bluetooth can't find the device.

Is there something I can try?
You need to put the headset into a pairing mode. According to the manual, the procedure is as follows:


Turn the headset off
Press and hold the MFB (Multi-Function Button) for 6 seconds until the LED flashes red and blue alternatively and you hear a beep
Search for Bluetooth devices on your phone and select the PHBT5
Enter 0000 as the PIN if asked
When the pairing is successful and active the LED will flash only blue regularly
