Mi piston
One of the best and low price earphones.
I have been using these since I got it from Aliexpress 1 month back.
The sound quality is simply superb.Clear audio clarity, Metal design, excellent wire quality, decent speakers with clear bass includes in these low cost range earphones compared to other earphones in market.
Bass is awesome and the sound is surrounding through the ear pieces only and never go out even high volume.
This includes a well built mic for calls and music control.Wire quality is also durable and there are extra 2 pairs of ear pieces in the box.
By the way I got it from Aliexpress for only 130 Rupees by using the 4 us dollor coupon which I have got at the time of signing up as a new user.
If you want a good earphones with low cost it is one of the best choices for you.
Note. This is piston 1 model.
