I have bought this earphone a week ago, and the best part of my experience is the comfort this product gives your ear even after a long listening of music.
The music comes out of this mind blowing earphone is balanced, sometimes you feel more Base and sometime treble. Now the frequency is 25000 Hz, which is pretty amazing thing you get within that value!
There are four color variants Red, Black, Blue, Lime green. I bought the Red color which matches my Mi note 4 black.
I suggest you to buy if you are willing to get a good piece under 700 rs.
