These are bad earphones mean not very bad but respect to other earphones of Mi this is a bad product . I have used these earphones in the past . Its bass is also bad not much bad but somehow it is bad . And these earphones are also not very good for our ears after 1 to 2 hour wearing you have to take out them because your ears start to get hurting from this earphone so it is not eco friendly . And its wire are very weak after some time they were tear and the wires were come out fom it . And its cost is also very high so if you are thinking to buy this earphone than cancel your idea.
