Hello friends, I buyed a MI earphone 4months ago.Three months it works very well but after three months it was not working.The sound cames out only from one phone and another one becomes totally sound less.I Excahnge this from service centre because it is in warranty period but what I will do if it not works when warranty periods over.The cost of it is 900 and if it will not works after some months then my money may be waste in this worst product.So I didnot suggest anyone for this product.
