I am used these headphones for 6 months. So, I think I can review it well. I purchased these headphones from Amazon. First of all, the major cons of these head phones are it’s bass. Really, the bass is not at all good. I am getting head pain if I used it for just 10 minutes. The jack they provided is also not good. After using it for 3 months, one side of these headphones, is not working properly. Coming to it’s sound quality, I can say that it’s just average. The mic they provided is working properly. So, better don’t go for it.
