Mi in ear headphones are one of the best headphone I ever seen. It is having best sound quality, bass, sleek design, awsome look. Whenever I use this product I feel very comfortable and relax. It costs not much than the others like sony, jbl, sanheiser etc. The company also provide 6 month warranty. Talking abouts its service than it is having very poor service . the company took arount 2 month to replace my product. But it is overally good if you see about its feature.
