Can't pair my VBT2050 with motorola Droid - Jabra Bluetooth Headset with Adjustable Ear-Hook Headset

Was the Bluetooth working before? This is something that has worked for other users: Unpair and forget you phone/car pairing then, a Clear Cache Partition process then, re-pair all and try it out.
It's not a definitve fix but has worked for many people in the past.

To perform a Clear Cache Partition:

your limit would have crossed
there are a particular no of devices that could be paired
Pair your Verizon Motorola Droid 2 smartphone with a Bluetooth device using these steps:
1. From the Home screen tap Menu > Settings app.
2. Tap Wireless & networks.
3. Tap Bluetooth settings.
4. Ensure that Bluetooth is checked.
5. Turn the Bluetooth device on and set it to discoverable if required.
6. Tap Scan for devices.
7. The Droid 2 should locate any devices in the area. You may need to enter a password. Most devices have a password of 0000 (four zeros).
The Bluetooth indicator should now show in the notification area. This indicates you are paired successfully.

To see if the problem is with your bluetooth connection, try sending and recieving files with your bluetooth. If it is successful, then try borrowing 1 jabra device and test it with your phone. The bluetooth connection and the jabra device are the problems I can see since you said it worked once.
Hope this helps! -jayps

I think I can help here:
Make sure your headset and phone are charged before doing anything else. The blue light on your headset will come on when it is charging, and will shut off when fully charged.
To put your headset in pairing mode, make sure it is completely off first (no blinking blue light). Then hold down the Call button for 6-10 seconds until the blue light stays on. (It will likely flash once and shut off, but keep holding until it is all the way on and stays there!)
From there, go into the settings on your Droid 2 and access the bluetooth connections. Do a new scan for your headset if you don't see it listed, pair, and connect!

you can only use one digit number not four digit..to detect the bluetoot headset

Here's the instruction manual for the H710:

You'll have to check your owners manual for your Droid, but it's probably under Settings > Connections > Bluetooth (Turn on) > Discover (Pairing code 0000)

You need to put your H500 into "pairing mode" by pressing the call button until the light turns steady blue, instead of blinking. Your droid will then see it when you are in the Bluetooth Settings screen under Networks & Wireless. I just did this myself last night and it worked fine. Be forewarned, however, that you cannot voice-dial with your bluetooth - only answer calls. There are several forums out there that are bashing Motorola & Google for not having this basic functionality.

ARE U FOLLOWING THE CORRECT PAIRING PROCEDURE
pls follow this

ok here u go first turn on the bluetooth func in ur mobile, now while ur bluetooth headset is off press the power centre big button for like 10 sec until the blue light stays on continously not blinking position ok then search for bluetooth devices in the phone bluetooth config ur headset will come up like JABRA VBT2050 select it then it will ask u for pairing code input 0000 and press ok ur device is now connected u will see the blue light which was continous b4 now blinking it means ur haedset is connected , u have to complete this process in almost 1 min bcoz there is a timeout for this process , now try any call u will hear it in ur headset

pls rate me fixya for this if it helped

I took my husband's suggestion and used 0000 and it worked. My husband claims it is the factory default for all bluetooth headsets. Try it and let us know if it works.

Jabra VBT2050 - You have to hold the round button in until the light stays lit (about 20 seconds) this will put it in discoverable mode, the pin is 0000, I have AT@T service and it works just fine. Hope this helps out!
