I am trying to pair my Bluetooth 3xx plantronics headset to my computer which does have bluetooth software can you help pls?

Once you make your phone discoverable, then put the headset into pairing mode by pressing the call control button until it flashes red and blue. The passkey is " 0000 " (four zeros). Here is a link for the pairing instructions:

Plantronics Explorer Pairing Instructions

Good luck from Headsets Direct!

The link between headset and phone has been compromised.

Probably the best thing to do is to go back to the beginning, Vecini. Remove the bluetooth headset from your phone's menu and any other bluetooth interference. You can, for a few seconds, remove the battery (if possible) from your phone to reset the unit.

Then follow the pairing instructions for the Explorer 3xx and your particular phone.

If you're still having issues, you can try the headset on another phone to determine if it's a headset or phone problem.

Take a look at the following to help pair the Plantronics 220 to a Bluetooth cell phone:

How to Pair the Plantronics Explorer 220 Bluetooth Headset

You can use the Plantronics Explorer 240 on your computer if your computer has Bluetooth built in. Just turn on the Bluetooth feature in the computer and pair up the headset. You can get a USB Bluetooth adapter if your pc doesn't have Bluetooth built in, then just pair the headset to the adapter. Here is a link for the 230 / 240 user guide, it will have the pairing instructions for the Explorer 240.

This is probably far too late now, but I'll post it for future reference. You first shut off your 330 then restart it, but continue holding it for around 8-10 seconds (usually it takes less than that) and the headset will start flashing blue and red.
You are now in Pairing mode a.k.a. reset mode. While it is flashing, tell your phone to start looking for Bluetooth devices and when it displays "3XX-Plantronics" (or something similar), you know you have the right thing.
Simply select that and enter the default factory code: 0000 and you now reset and paired the headset!

the passcode is 0000 for the plantronics 3xx/360

If you have lost the pairing on your phone with the headset follow these simple steps below:
• Setting the headset into pairing mode
1) Ensure the headset is fully charged
2) The headset must be switch off
3) Press and hold the on button for +- 8 seconds until the light flashes red-blue
4) The headset is now in pairing mode
• Searching for the headset on the phone
1) Go to “settings” or “connections”
2) Select Bluetooth, then options
3) Select Devices and click add
4) The phone should search for any available Bluetooth devices and display what was found
5) Select the Explorer 3XX device and click add
6) You will be required to enter in a pass code which is standard ‘0000’
7) If successful then the headset will start flashing BLUE every few seconds.
8) If it’s a Samsung or Nokia phone you will need to “AUTHORIZE” headset on the device.
