Lenovo a2010, quantity :2, delivered on 6th jan 2016 ordered via flipkart.
Both models for my parents.
When i randomly checked today, the earphone for one of the models which was never used since the delivery, as my dad does not listen to music on the phone, is not working.
The other one fortunately, was working since the day 1.
