Ответ на "How to fix power to Bose QC2 headphones"Thank you all for this post!!! I have the QuietComfort 15 and after I saw that my last battery leaked inside, I thought it was a goner. I tried what most people posted here (vinegar, normal saline, and pencil eraser), but what worked for me was a q-tip dipped in rubbing alcohol. I cleaned both positive and negative terminals, and dried them with a power duster (compressed gas duster).. about to give up hope and BOOM - it WORKED!!! Thank you all, this thread has made my day (and saved me $$$)!!!
