One of the most commonly asked questions I get is "What is the PIN code for pairing a bluetooth headset?". You are prompted to enter this 4 digit code when you attempt to "pair" (pairing is configuring your headset to your phone or device) your headset. It's real easy, the PIN code is 0000. That's right it's just four zero's, the PIN is the same regardless of brand or model of headset. So if you need the pin, here it is, and I hope this helps.
