So … I got a bluetooth headset that was damaged – the earphone wires were pulled out – so got them soldered back and all was good – however I couldn’t get the device in paired mode. The version I had was the version 1.0 version. This solved my problem.
Turn the device off – hold the power button for about 5 seconds until the blue ring light stops flashing … wait a while.
Hold the power button down for about 10 seconds – the ring light will flash red – device is now in discoverable mode.
On your mobile device (iPhone) for me – Settings > Bluetooth > Search – it should pickup Headset. Click on pair
The passkey code is ‘0000’ thats zero, zero, zero, zero – paired and you’re done.
