I bought these earphones @1099 rupees from amazon on 30-nov-2019. The earphones are of plextone company as mentioned on the amazon website.
In the warranty, section amazon has mentioned a 1-year warranty with this product and have not provided any website for the same.

These earphones stopped working after 8 months. The company has not provided any warranty information hence i'm not able to claim any warranty
