Hey friends!!!!
Here I am sharing my own and true experience.
I was using the boat nirvanaa uno in ear earphones. I was not happy with this boat nirvanaa in ear earphones product I suffered badly.
I was not able to watch a complete movie and I was not able to hear the songs for 30 minutes.
And this boat nirvanaa uno in ear earphones was hurt me very badly and after some days nearly a month it got damaged.
I strictly recommend do not use the boat nirvanaa uno in ear earphones.
