Today I am sharing my own experience of using i-ball headphones.I bought these headphones about 15days earlier.
They are already worn out. First of all the sound was good but in 5/7 days it got bad. Moreover one side of headphone came out of socket in normal use only.
I think it is a bad headphone to buy. You can better go with boat rockers.
These does not even pay the value of money.
