I purchased this headphone few months back.I am writing this review on behalf of my personal experience .Actually in starting few days of its purchase the headphone was okay but after few days, after listenting songs more than half and hour I was having headache, I thought it happend due to some other reason but soon I got to know that it happened due to headphone only.
I purchased this in rupees 600 ( offer price) and current from flipcart it is 799 rs.So currently I am using apple earphone and which is very good and no sign of pain you will in it.
so my personal suggestion is not to buy this , please refer to apple or jbl or some good earphone /headphone as your ears are very precious to you.
thanking you.
