It seems that not all tfp has this problem. The plug on my tfp right earpiece was easy to pull out. Only the left side was broken so easily.
Anyway, I have contacted UE (now Logitech) about this issue (I did mention head-fi). They seem to accept this problem as a defect. If your product is still under warranty, you just have to send the broken one in and they will send you a replacement.
As for my case, my tfp is out of warranty. They offered to me to buy a tfp from them at 50% discount as long as I send my broken tfp in. Pretty much useless since tfp is $400+tax at Logitech website. I may be able to get one from amazon for slightly cheaper
