In summary, Yamaha DGX 670 is one of the best choices if you want a premium and versatile product without hurting your budget too much. Now let’s jump to its in-depth review. 

Highlight Features Of Yamaha DGX 670

All the critical aspects of a piano, like the design, build quality, and sound performance, are on point. Some of its qualities even exceed my expectations. 

The sections below will provide you with an overview of its best features. 


The appearance of the Yamaha DGX 670 is a significant leap from the previous series. Compared to its successor DGX 660, it possesses a much more beautiful and modern design. 

The most apparent upgrade lies in the piano’s body design. Though the primary material for its body shell is made from plastic, its texture appears much smoother and sleeker. 

The build quality is also decent and reliable, though it’s not as excellent as the other high-end series. You should not expect any issues like cracks or body construction to wear down in the long run. 

The piano’s size is also massive, with up to 47 pounds in total weight. Therefore, it’s not the best choice for customers prioritizing portability and lightweight, though the product’s total weight is not overwhelming. 

Yamaha DGX 670 is significantly heavier than the other products in the same price range, such as the Yamaha P-125 (26 pounds) or Casio PX-360 (26,2 pounds). 

Though Yamaha DXG 670 is labeled portable, it’s one of the heaviest portable products with a significant heavyweight. If you casually carry the piano around, this heavyweight would be a significant disadvantage.


The controlling interface of Yamaha DGX 670 is very well-designed and easy to navigate for new users. Its control layout resembles the user interface of the  PSR-SX900.

The buttons are made with rubber instead of plastic, delivering a more premium and reliable look. They are very solid and soft to the touch, which won’t wear down or generate cracking sounds in the long run. 

Yamaha also installs small indicating lights for important buttons, adding more ease of usage and a more attractive look. There are two knobs to adjust volume, which are very smooth and decent-looking. 

The highlight of its interface is definitely the 480×272 color display to help users locate different functions and adjust the device easier. The added color is a significant improvement, which increases the display’s contrast and readability. 

Yamaha has eliminated the Numpad for switching sound and replaced it with category switches. All these features make up an efficient and user-friendly interface that can be used even without the owner’s manual. 


Similar to many other Yamaha series, DGX 670 features a full-sized GHS keyboard with 88 full-weighted keys. With the graded keyboard and the force-sensitive feature, the keyboard feels alive and realistic to the touch.

The black and white key materials are all plastic, providing a sleek and shiny surface. However, the plastic texture is a little uncomfortable for users with sweaty hands due to its lower grips. 

All these features bring you an authentic playing experience, like using a grand acoustic piano. The key’s return is still quite springy, but it won’t affect your experience much.

Sound Quality

There’s not much to complain about the sound quality of Yamaha products, regardless of their targeted customers and price ranges. The DGX 670 delivers up to 29 drum kits and 601 sounds. 

This diversified sound collection is a great leap from the previous DGX 660 version, with only 15 drum kits and 539 sounds. You’ll get excellent audio quality from different instruments like:

  • Drums
  • Synth & Pad
  • Choir & Strings
  • Bass 
  • Guitar
  • E.Piano & Piano
  • Organ


This piano has 4 sets up of integrated front-facing speakers to generate its sound. This speaker system consists of two dual speakers, one main speaker (12 cm), and a tweeter (5 cm). 

With up to four built-in speakers, Yamaha DGX 670 can deliver sounds in different frequencies, but the low power capacity is a drawback of this device. 

This setback results in unimpressive voices and the loss of many subtleties from various sound engines. Nevertheless, the DGX 670 can accommodate an excellent hearing experience if you set it at a medium volume. 

The sound is very loud and clear at all frequencies when combined with the speakers’ dynamic response. However, the audio quality is compromised when you push the volume higher. 

Using a headphone with DGX 670 will deliver a better experience than using its front-facing speakers.

Special Technologies Of Yamaha DGX 670

The features and technologies equipped with Yamaha DGX 670 are impressive considering its price range and “portable” label. Here are some most noticeable features you will find interesting. 


VRM, or virtual resonance modeling technology, creates authentic resonances delivered by a grand piano with vibrating strings. The resonance on Yamaha DGX comes from the high-end CLP Clavinova.

Thanks to this technology, the Yamaha DGX 670 can generate up to 9 VRM sounds for a more lively and immersive playing experience. 

Meanwhile, the S.ART (super articulation) sound engine allows users to record and track their own playing. You can utilize this technology to control and mix your record better by adjusting the sample types from soft to hard. 

Other Sounds And Effects 

The guitar sound is my favorite on the Yamaha DGX 670, with excellent and authentic audio quality. It feels very fun and natural thanks to the dynamism of the super articulation technology. 

The organ sounds are also worth trying, especially when playing jazz or electronic music genres. You can also get the solo woodwind and brass sounds, which are pretty unique and exhilarating to hear. 

Microphone Connectivity

The Yamaha DGX 670 supports a microphone input combined with some good vocal effects. However, you will need an outer device like a mixer or laptop to mix and edit the track.

USB Audio Playback

You can plug in a USB to the DGX 670 via its USB connection and play back your recorded audio. The piano even allows users to change the pitch or the records, along with their volume and playback speed. 

Notation Display

The notation display feature is super helpful for practicing new songs. This high-end feature not only adds more value to the piano but also increases the premium appearance of your device.


There is a ¼ inches jack output to plug in your headphone or amplifiers because Yamaha didn’t include the stereo outs on the DGX 670. In addition, the Bluetooth connecting options are a major selling point for DGX 670. 

They allow you to cast music and sounds from your Bluetooth device straight to the piano without the need for any connecting cables. Unfortunately, the Bluetooth function isn’t compatible with MIDI yet. 


The items included in the box are the owner’s manual, one footswitch, a music rest, an AC adaptor, and the power cord. These are the basic tools you need to play piano properly.

Though the footswitch can serve as a sustain pedal, I recommend you get a more premium pedal, plus a headphone to get the most satisfying experience on Yamaha DGX 670. 

Final Verdict: Should You Buy The Yamaha DGX 670?

In summary, Yamaha DGX 670 is an ideal choice for singers, composers, and live performers with authentic and excellent sound quality. Its premium and modern features will fully accommodate all your needs. 

This piano delivers the highest value if you can utilize its collection of backing styles and sounds. High-tech composers can mix their records with more lyrics and effects before transferring them to another device via a USB connection. 

Yamaha DGX 670 is also excellent for live performers with its ‘Adaptive Style’ technology, allowing the performer to lead a large group of instruments. 

Besides, if you just look for a beautiful and authentic piano at a reasonable price, Yamaha DGX 670 is still my recommendation. 

I hope that this Yamaha DGX 670 review can help you make a wise purchase decision. Thank you for reading!
