There's a bead stuck in my headphone jack?

kdmirissa, the poking may have cause the bead to be further lodged into the audio jack. You could try with some suction, i.e. vacuum cleaner etc. to see if your get it out from there. If it is a plastic bead, you can also try to take a needle , heat it up till it glows red and puncture the bead, keep the needle still while the plastic cools down. then, gently try to pull it out. Should any of this fail, you may have to replace the jack. It is available at places like this. For instructions on how to it, check this video. Hope this helps, good luck.
