Another option:
Short the too small capacitors, so there are no capacitors at all. Then 
add the big caps outside the screeming, but this time with no need to 
connect to anything inside the screening.  Just break the connection 
anywhere, and insert a nice big cap. The easiest place of all then, is 
obviously to add the caps to the headset. Of course then you only have 
one useable headset.

Or break the connection between the plug and circuit board, and put the 
caps somewhere inside. There is lots of room above the SIM card.
