WEP170 headset Although the above is Samsung and  the headset is also Samsung -my mobile doesn't see it.....My bluetooth finds everything and everybody else..... so why not the headset???

I assume you mean the code for the headset?
The default is "0000" when pairing.

1.
Ensure the headset is off (see Turning headset on/off section).
2. Press and hold Power until you see a solid blue light (approximately 8
seconds), then release* (see Fig. 3).
3. Set your Bluetooth phone to "discover" the headset by following your phone's
instruction guide. Typically, the steps involve going to a "setup", "connect", or
"Bluetooth" menu on your phone and then selecting the option to "discover" a
Bluetooth device.
4. Your phone will find the "Samsung WEP170" headset and ask if you want to pair with
it. Confirm this by pressing "yes" or "ok".
5. Enter passkey or PIN4 = 0000 (4 zeros), then press "yes" or "ok".

You need to put the headset into pairing mode for the phone to be able to find it. There are some instructions on this page:

Please follow these, hopefully they will help solve your problem

Yes. To put your headset into pairing mode:
1.) Make sure your headset is off.
2.) Hold the Power Button on until the blue light stays lit (about 8 seconds). This puts it into pairing mode.

You don't have to reset it, all you have to do is:
1.) Make sure the headset is off.
2.) Push and hold the 'On' button until you see the exterior light stay blue (about 8 seconds). This puts your headset into discovery mode.
3.) On your mobile, go to the bluetooth menu and set it to search for Bluetooth devices.
4.) When it finds your headset, tell it to pair. If it asks for a passcode use four zeros "0000".

Hey dude,
U dont need to search for the pass keycode. It is the key u put on. Put on the same code on bluetooth which u have put in ur mobile/PS3.

must start with headset turned off.
1) turn on headset and keep your finger pressed until the blue light stays on
2) now let your phone search for the device. when it does select it
3) the pin is 0,0,0,0
4) then it should be matched

I bought a pair of Sony headphones for my MP3 player, they came with three sets of rubber covers for the bud part of the head phone.
I have the WEP 170 also but didn't like how it fit in my ear, so I took one of the Sony bud cusions and replaced it with the one on the WEP, works great and even helps to cancel out noise.

Hope this helps
