I have a pair of ATH m50's that has a broken 3.5 mm jack.  The jack itself got stuck in someone's phone that they jammed into too hard.  I have a picture of the broken audio jack.  I am wondering if there is a cost efficient way of repairing them that won't cost more than the actual price of the headphones.  I have a picture attached below.

Absolutely cheap to replace.
There are guides on soldering around here, just search.  Soldering is easy.  You can post in the DIY forum for help.  There are probably threads on reterminating headphones, such as you need.  Reoplacement plugs are very cheap, just look up Neutrik 3.5mm stereo plugs and Amphenol 3.5mm stereo plugs.
