Trying to pair my HTC EVO to plantronics explorer 233 Bluetooth headset

I would try 0000 if it is a brand new headset that is the universal default password for those hope i could help =]

The Plantronics Explorer 232 is compatible with the HTC Inspire. 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. Here is a link for the pairing instructions:

The headset must be put into pairing mode. Once you make your phone discoverable, then put the Plantronics 230 headset into pairing mode by pressing the call control button until it flashes red and blue. If it's not flashing red and blue, then it is not in pairing mode. Here is a link for the pairing instructions for the 230 headset:

The default pairing code for Plantronics is 0000 (4 zeros). If you need more help, try their interactive pairing guide: http://www.plantronics.com/media/media_resources/easytopair/

The code will most likely be "0000"
or try "1234"

When joining (or pairing) a Plantronics bluetooth headset to another device a lot depends on the other device. Assuming that you know the necessary steps of your phone or PC for connecting a bluetooth device, all Plantronics headsets pretty much follow a set pairing procedure for connectivity. This one is for the Discovery 975:

1 Turn on the Bluetooth feature on your phone.
2 Turn the earpiece on. Press and hold the call control button until the indicator flashes red/white.
3 Use the commands on your phone to locate and select your earpiece. 9xx Plantronics.
4 If prompted for the PIN code or Passkey, enter 0000.

Pairing is successful when the indicator on your earpiece flashes white.

Note If your phone supports Secure Simple Pairing (SSP), you will not need to enter a PIN code or Passkey.
