Hi guyz . Today I m gona tell you about jbl c100si headphones. I buy this headphones last week from amazon. As you all know that jbl is one of the leading brands in this line. So I buy this. But I m not satisfied with this product. Sound is not very much good. Bass level is a bit good but overall sound is not satisfactory. Build quality is also not good. Now I buy 1 more earphones and I must they are far much better than JBL set. Cost is almost same. So I prefer you guyz is you want to enjoy full music then go for another headphone. Thnx
