Jabra manufactures and markets a line of Bluetooth headsets that are fully compatible with the iPhone.

After you've completed the initial pairing process, the devices will automatically connect in the future when they are switched on and placed within range.

Select your Jabra headset from the list of Bluetooth devices on your iPhone.
Enter "0000" when your iPhone prompts you to enter the pass code for the Jabra headset. Wait while the devices complete the pairing process. Your iPhone will prompt you when the pairing is complete and the devices are connected.
