HD660S left side dead after 3 years
Expensive Headphones... bought them 3 years ago shortly before the release of the 660S2. Always well cared for, always put in a protective case.
Now there is only sound on one side. Checked the Cable and Contacts, both are fine. This happens of course shortly after the warranty is over.
Repair quote by Sennheiser is 213 EUR, about half the original cost. I´m utterly disappointed in the quality, all my cheap in ears lasted longer.
Now is there a way for me to somehow exchange the left driver or repair it myself for cheaper?
