I have too much thing purchase from amazon. Some days before I purchase a senhiser cx-180. I have found a defect in that after 1month. You know amzon not only return my money but they not taking their product. You can see how much they are loyle. Basically I am telling about that if you are getting a defecting product by amzon don’t be panic. Just call the customercare they take all the details of your product and they give you reply within 3 -4 hour. After some time they will return total money
