What is Pngmall's returns policy on earphones and headphones?

Due to health and hygiene reasons, earphones and headphones can only be returned for a full refund if they are unopened within 30 days of purchase and are completely sealed or faulty.

For this reason, if you have changed your mind about your purchase, earphones or headphones must be completely unopened and unused to receive a refund. 

If, however, the item is faulty then the standard Refund and Warranty policy applies.
