I have been a long time owner of all things Klipsch. My biggest disappointment, other than the occasional ear bud failures which were replaced by Klipsch, is the earpieces in the M40 headphones. My noise cancelling still works, but the cover on the ear pieces are completely shredded. In looking at this forum, I see one person offering a solution via a replacement part sold on ebay, but that link is not active. So has anyone found a current replacement option?
