CoolTechZone has posted a Samsung T7 Series MP3 Player Roundup

As far as the audio quality is concerned, the player performed
exceptionally well. The sound quality was almost perfect from a player
this size. The independent equalizer settings along with TruBass and SRS
effects really supported the sound and made it sound above our
expectations with each genre. The notes and pitches were precise and to
the point.
