It depends on what kind of music you listen to. sony is the first choice for rock music, but Samsung's q2 and p3 are better for light music. Forget it for Apple. Apple is not a company that focuses on sound quality at all. It sells industrial design. By the way, I would like to add to the landlord that only one mp3 player with good sound quality is half finished, and a pair of good earphones is needed to give full play to its functions. There are many good earphone manufacturers, such as Tiesanjiao, Sennheiser, Tianlong and sony. The landlord might as well choose according to his favorite music type, which is nothing more than the degree of reduction, the effect of high school and low frequency, and the sound dyeing. It is not difficult.
