They write a lot of reviews, both positive and negative, I would like to clarify the situation a little. The sound quality depends on the device on which the music is played, on the player (equalizer settings), on the track itself. It depends on what kind of music you listen to (style). My opinion is a solid four .I listen on the HTC Desire 530 phone through .Music. The "electronic" style, to my ears, at a higher volume cuts a little at high, at medium volume it's excellent.
