Broken wire on headset

It sounds like you may have a broken wire inside. I would inspect the circuit board on the left side of the earpiece first. Look for shorts, broken wires or anything that looks burnt. You can use a multi meter to make sure the wires in the neck band are not broken. Here is the video showing how to open it up:

Re buying a repair, then too much trouble.

I just dealt with one of these last month, its a ten minute fix if you have a soldering iron. The wire gets strained inside, they didn't allow enough slack in the wire for the movement of the earpieces. A quick resolder of the broken connection and a dab of hot glue to keep it from moving was all it took. Cost of repair was zero.

If the wires are open or the connections are visibly broken then the connections can be mended. But if there is fault in the earpieces then I suggest that cost a new one must be checked before you think of getting this repaired.

I've had this happen twice with Logitech headsets and believe it has to do with the cheap/fine wire they use in the cables. I suspect that a good tug on the cable will snap the wire or some other internal connection.

Friend you need to use a electronic tester and a slodering iron. just solder the cut wires and test if it has connectivity

Same thing happened to me. For about $5, I went to Home Depot and bought 24 gauge wire (about 5") and a pack of black heat-shrink plastic sleaves (1/8th inch or 3/16) from the electrical department. The 24g wire fits perfectly through the rubber slot after you pull out the broken ear hook. Use a pair of pliars to bend the wire to shape your ear (use the broken jabra ear hook as a template). Once you have the right shape and have filed down the sharp edges, slip the heat-shrink plastic sleave over the wire, making sure you leave the end piece that goes into the slot of the headset as bare metal. Use a hair-drier on high-heat to shrink the black plastic. Mine has worked perfectly for over a year and actualy fits better than the original.

i just cant create a connetion to connect my headset to my phone! what am i goin to do?

It's doable, but you might wan't to consider buying a stand alone mic, they come pretty cheap. What you need is a speaker with internal amp, and a new pl jack - you cant just patch it into the wire that went into your earpiece, its a different kind of wire. When you go to radio shack or equivalent to get the jack, ask them to show you what kind and exactly how to go about it. Not very complicated, but maybe unnecessary. Good luck
