SOURCE: Not sure if Jabra bluetooth headset or charger that not working

I had the same problem, called support, they told me battery is defective or too old and doesn't accept the charge. Battery in a headset is hardwired and can't be replaced, so the whole thing is trash :(

If you hold down the button, it will turn the light blue, keep holding it till you can connect it. It will come up as Jabra BT125, hit connect. Then it will ask for a password. The password is 0000. Then it will connect :)

SOURCE: Jabra JX10 Bluetooth doesn't/won't charge

Not sure if this is a solution or if it occurred by chance. Like many on here, I put my Jabra JX10 away for a few months while not using it. The time come for me to need it once again and found that it was dead. Made an attempt to charge the unit with negative results. The unit would only show a green "charged" LED indicator as if the unit was fully charged. I tried plugging the unit into the charger multiple times, and took the cradle out of the loop and just used the AC cord alone. Still with the same results. I pulled the outside cover off (slowly), to be sure not to break the small fragile tabs that hold it in place. The battery takes up majority of the space. Removed the battery but DID NOT disconnect from unit. Plugged the charge cord into the unit and immediately got a red LED charging indicator. While charging, placed the battery back inside and put the outside cover back on. The unit continued to charge for a little over an hour before the green LED "charged" indicator came on. I used the unit throughout the day to test it with no problems. Not sure what removing the battery from unit did, especially when it was not disconnected, but it worked. I hope to see similar results.
