Thanks!!   But I tried and I can't find it in ebay,   can you please help me and send a link? maybe you have recommendation about a good comfertable kind? (if it make any different, I have big ears :) )

Hi everyone,   I lost one of the arch that you connect to the headphones so it is more comfortable to wear them.   I tried to find where I can buy them online, but failed,   Does someone knows about a site where I can order it?   Thank ahead, UV
