Very good and on schedule

Rewarding!

Recomendo!

Quality sound great! Fits very well in the ears. Isolate the external sound as good to walk in the street. Has many bass, average reasonable, and treble great! Very worth the price. Have the Xiaomi hybrid pro, comparing the zsn has more serious, less medium and treble almost equal. Use the street the bass are great, home in silence can be exaggerated or bother.
