Hello head-fi,
 
Newbie wanting to modify my Panasonic HTF-600-S headphones.  I will try various recommended mods, but could you diy modders please let me know what each mod typically does...i.e. - adding foam, removing foam, blocking holes, adding holes, new pads, adding tissue..where, how much, and affects would be greatly appreciated.
 
Thanks everyone.  I'm extremely green, but eager to try some mods.  Personally looking to add punch and cut some highs.
Mike
