I am using this in-ear earphones for long time, it gives the best sound quality . The bass line gets the deserved justice with this product, its 3D surround sound output adds to the taste in the best way!
Sennheiser comes among the best earphone and speaker makers in the world and This product is one of the best from them.
It compitable with all mobile phones too !
I strongly recommend this to all, specially for them who knows the music and choosy about its quality !
Fantastic, fabulous and a true beauty !
