The Yamaha DGX-670 is a “do-everything” 88-note digital piano that combines a serious graded hammer action and flagship CFX concert grand sound with powerful speakers, auto-accompaniment, Bluetooth audio, mic input, and recording tools.
It’s perfect if you want:
-
a proper piano feel for practice and graded work,
-
band-style accompaniment and hundreds of sounds for fun and songwriting,
-
and a single instrument that covers home, studio, worship, education, and live use.
Independent reviewers consistently highlight three things: authentic piano tone, impressive key action for the price, and huge versatility—making it one of the strongest all-rounders in its class.
