1 yr warranty void in Dec 17.It happens. Even my sennheisers Cx180 left earbud was dead twice within one year. Got replacement both times under warranty. If your headphones are in warranty, you can get them replaced.
btw my boatheads earphones went dead on right one. Even those were exchanged under warranty
great spark!. Better to do some hands clean work... Any DIY feedback here would help me more... Thanks foruamitor you can do desi jugadh, cut the right peice from one and attached it in left side of other set.
