I had a laptop given to me this morning by a student at a school I do some contract support work for that had a 3.5mm heaphone jack snapped off and stuck in the headphone socket. I tried at first to see if I could dislodge it using a very small screw driver and some tweezers but it's virtually impossible as the more you try to move it, the more you seem to make it even more stuck in the socket. So off to google I went and found a few things to try for getting the broken off 3.5mm headphone socket out including toothpicks, straws and a biro pen inside tube. I went for the biro pen option as I had one handy and all it basically involved was removing the inner plastic tube from a normal cheap pen and then putting a small dab of gel based super glue on the end of it. Then you simply insert the plastic tube into the socket and it should fit snugly over the broken off headphone jack. Next, give it about an hour to set and then gently pull it out. I followed the steps to the letter and was honestly really surprised that it worked first time perfectly and easily removed the broken off headphone jack. A little tip though, go easy on the glue – the last thing you want is to glue the pen tube to the sides of the socket which will create a much bigger problem for you. Avoid the cheap watery runny super glue too, get the decent quality gel stuff so it doesn't go everywhere and you should be good to go 🙂
