Yeah, replace them... I posted some pics on how to do it really professionally with hair elastics... all it takes is a small file, some crazy glue and patience. The images are here: http://home.cogeco.ca/~philodox/K340/new/
Thanks a lot for the thread and pics!!! Can't wait for my K340's to come!!
How is the difference before/after the screen mod? I plan on completely removing the plastic screen, and glue some speaker fabric on the back of the earpads to cover the eletrodes. But would things get loose without the screen holding them?
