Well I for one would not be sticking sharp metal objects down my ear, Go to the ER or your DR and get him to take it out!
Either that or put a couple of drops of Olive oil down your ear and gently massage the base of your ear pushing outwards. The human body is wonderful on it's own at expunging foreign objects as well!
Repeat, DO NOT PUT SHARP METAL OBJECTS THAT FAR DOWN YOUR EAR CANAL, YOU COULD PUNCTURE YOUR EAR DRUM
Tweezers should be fine. You're not going to puncture anything with the tweezer because the iem sleeve will protect your ear drums.. Be sure you let someone else do it for you coz they'll be able to see inside your ear.
Ha ha, I remember when that happened to me with my tfi's, fortunately I was at the university and asked the doctor to take it out. The last thing that came to my head was asking for help at a forum... imagine waiting 8 hours with that in my head, no way!
Actually, puting your head inside boiling water for 3 hours sounds like a good way to take it out, tweezers are for girls!
