I had brought a ubon ub1085champ white coloured earphone that is going good for sound quality at starting .
As the 2-3 months letter , the sound quality is decreasing and is not usable during the calling because of in that the clear voice is not coming .
Also , the manufacturing quantity is also third grade because of some time one earphone dead from two.
The mic of earphone not working properly after 3-4 months.
