I just wanted to tell its a wow earphone from sony. Previously I owned this type of earphone of blue color but it was without mic and it lasted for 3 years, so its value for money. Later after a few week I buyed this product and I feel like sony is back in action. Its very comfortable in my ears whether I jog, run, skip or jump, it never fell down from my ears. It really looks sporty in my ears. The bass quality of it really feels me the true effect of the music. I am a happy customer of sony. Thank you Sony.
