Clean powerful sound

Works smoothly on plugging right out of the box. Sound has volume and depth with accurate stereo, treble is smooth and bass is extended. There is compatibility issue with headphone cables that have mic. Very good sound output with its high spec components.

Thank you so much for your feedback!
