I bought this earphone at Feb. this year. But my friends bought me another same one. It is brand new and I only use it around 2 times. You can totally lose yourself in your music and tune into your environment.

This earphone is for iPhone device and market price is $326(with tax).

You can get it $290.

Check it out online.
