I bought them 2 months ago but couple of weeks ago I was listening to songs and suddenly the right plug stopped working. There is no physical damage over headphones but still it stopped working. There might be any internal defect. Otherwise the build quality of headphone is too good. I had contacted the service they picked up the headphones from my address but now after 10 days there is no further contact by boat to me through any medium.
No idea whats wrong! Its a good choice only if they provide more better service.
