One of my Indy earbuds is buzzing?

I bought them almost a year ago. Nothing happened to them (they didn't fall or encountered with any liquid.). Right earbud started to buzz but it was simultaneous, buzzing sound only came for 2-3 seconds. Yesterday it started buzzing and never ended. Even when I put them on, power on sound that comes from right earbud is so slight. What could be the reason and how can I fix it :/ In my country, Skullcandy only has a distributor company and I can't reach the costumer service.
