Our Verdict
The DGX-670 is half piano, half band. With 630 sounds, auto-accompaniment styles, and a full 88-key weighted keyboard at just 12.4 kg, it's Yamaha's answer for players who want more than just piano practice.
Pros
- • 630 built-in sounds covering piano, strings, organs, synths, and full band ensembles — far beyond any pure piano model
- • Auto-accompaniment with rhythm styles lets you play along with a virtual band in jazz, pop, Latin, and dozens of genres
- • 88 weighted keys with GHS action at only 12.4 kg — genuinely portable for gigs or moving between rooms
- • Bluetooth MIDI for wireless connection to the Smart Pianist app
- • Built-in lesson function with 260 preset songs and recording capability
- • Line out and dual headphone jacks (6.3mm + 3.5mm) for both stage use and quiet practice
Cons
- • GHS action is Yamaha's entry-level weighted action — noticeably lighter and less nuanced than the GH3 or GH3X in higher models
- • No Bluetooth Audio — you can connect via MIDI wirelessly, but streaming music through the speakers requires a cable
- • No headphone sound optimization — headphone practice lacks the spatial realism of the CLP and P-S500 models
- • Stand sold separately, adding to the total cost
- • Matte key surfaces lack the ivory-feel texture found on more expensive Yamaha models
The DGX-670 is the Swiss army knife of Yamaha's 88-key lineup. No other model at this price gives you weighted keys, 630 sounds, auto-accompaniment, Bluetooth MIDI, and genuine portability in one package. The trade-off is clear: the GHS action and lack of headphone optimization mean it's not the best choice for serious classical practice or late-night sessions. For that, the P-225 or P-S500 are better picks. But if you want one instrument that can do a little of everything — practice, perform, compose, and entertain — the DGX-670 at $900 is hard to beat.
Technical Deep Dive
About the Key Action
The GHS (Graded Hammer Standard) action is Yamaha's most basic weighted keyboard. It's lighter than the GH3 or GH3X found in the CLP series and P-S500 — you'll notice less resistance and a shorter key travel. For classical technique training, it's a compromise. But for the DGX-670's real purpose — playing a variety of sounds, performing with accompaniment, and gigging — the lighter touch is actually an advantage. Your fingers won't fatigue as quickly during a two-hour set, and the lighter weight makes the action practical in a 12.4 kg instrument. The matte key surface is functional but lacks the premium feel of ivory-textured models.
Who Is This Piano For?
You don't just want to practice scales — you want to jam. Maybe you play at a local church, a small café gig, or you just love sitting down and playing pop songs with a full backing band behind you. The DGX-670 is for the player who wants versatility above all: real piano practice when you need it, 630 sounds and accompaniment styles when you want to have fun, and the portability to take it wherever the music goes. If you're a pure classical pianist, look at the P-series instead.
