Our take on the Yamaha DGX670B Portable Digital Piano with Built-In Speakers

The DGX-670 is an 88-key portable digital piano that pairs a graded hammer-action keyboard with a full arranger engine, built-in speakers and a color score display. It sits above Yamaha's P-125 and below the Clavinova line: more voices and accompaniment styles than a plain stage piano, but a plastic cabinet and no wooden keys. It suits players who want realistic piano feel plus backing bands, vocal effects and on-screen learning. Owners praise the touch and sound for the money; some find the arranger menus deep and the action heavier than expected.

  • SoundPraisedThe piano voices and speakers are described as full and clear for home playing.
  • MenusCriticisedReviewers find the arranger settings and menus take practice to navigate.

Questions and answers

Is the DGX-670 good for a beginner?
Yes, if you want arranger features and a score display to learn from. Its weighted keys build proper technique, but a simpler slab piano is easier to start on.
How does it compare with the Yamaha P-125?
The DGX-670 adds accompaniment styles, a color display, mic input and more voices. The P-125 is lighter and simpler, with the same piano-focused approach.
Does it have weighted keys?
Yes. It uses Yamaha's graded hammer action, heavier in the low register and lighter up top, with adjustable touch sensitivity.
Can I connect headphones and a microphone?
Yes. There is a 1/8-inch headphone jack for silent practice and a microphone input with vocal effects for singing while you play.
Do I need the UD-WL01 adapter for apps?
For wireless iPad app use, yes. A USB cable connection works without the adapter.
What is in the box?
The piano, a music rest and a power supply. A sustain pedal and stand are not included, so plan for those separately.
