I bought these earphones in 2014. By seeing these earphones, I thought that it would be poor. But when I started listening by these earphones, it simply made me fell in love with these earphones. A special feature, Noise isolation makes you to listen the true sound by isolating the sound from your surroundings. Compatible with every mobile phone and mp3 mobile. I had used this product with sony walkman mp3 player and also some high end mobiles. It was truly a great experience. Build quality was good. The only thing is you don’t have any control buttons and a microphone. Simply I would say, a worthy product under Rs800.
