So I work in another country and couldn't walk with my Yamaha MODX8 (which is one of the best synthesizers on the market by the way). I needed a new keyboard to practice and watched tons of Youtube video to decide which board to buy that was under $1000. I was split between the Yamaha DGX 670 and the Kawai ES110 (which is around the same price range). I was also a bit skeptical after watching the reviews that complained about the quality of the speakers. I settled on the Yamaha DGX 670B because it seemed to offer more in terms of Styles (and backup band). I can say definitively, that I haven't regretted the decision. This board exceeds my expectation. The piano sound is beautiful, and the speakers are really good, defying what I heard about the onboard speaker quality. While it doesn't have the means of loading Yamaha's flagship Bosendorfer piano sound (like I could with my MODX8), the Yamaha CFX grand sound is really nice. Plus there are two other major piano tones (if you don't like the Yamaha CFX default sound), as well as many other voices. This board makes me not miss walking with my MODX, and the key bed feels exactly the same.CONS:(1)I am not sure whether the keybed is fully weighted as my previous Yamaha MOXF8 had a heavier action(2) The keys only comes with double sensors unlike the Kawai ES110 which has triple sensors, hence the Kawai ES 110 are more suited for advanced pianists, especially when playing thrills and other ornaments.(3) The key bed doesn't come with key escapement as in the P515, which gives a closer feel to a real piano. But the Kawai ES110 doesn't have this also.(4) You can import new styles but you can't import new voices or samples.(5) You can only play a maximum of 3 voices at the same time (1 with your left hand and 2 with your right), while other more expensive boards allow you to play as much as nine voices at the same time.(6) This keyboard is waaay too heavy. My more advanced MODX8 feels significantly lighter. Hence, it is not advantageous for mobility reasons.Overall, this board is a great buy. Easy to use, really professional sounds, arranger functions, etc.Update: It's now almost three months since I bought this board and I'm still enjoying it. Great buy!Today, July 30, 2022, I learnt that I could hook this digital piano up to my laptop via a USB cord (these small details are not in the user manual), and without needing to buy a MIDI/Audio Interface for US$120, I can take advantage of DAW and virtual pianos on my laptop, seamlessly. This keyboard has the ability to do that. Which means that you can expand your available piano or organ sounds via KEYSCAPE, Alicia's Keys, PianoTeq, etc. or any other of your favourite virtual piano sounds. You would just need to turn your Midi setting on your board on, and turn the keyboard volume off. If you want to use your VST to bluetooth the sound back to your DGX Onboard speakers, you must install the Yamaha Steinberg driver, which will remove the delay experienced.

I am NOT affiliated with any company, so this is an honest review. I’m definitely happy with this purchase. I like it better than my previous, more expensive keyboard which was a Casio Privia PX-560M. The internal sounds are better for almost every instrument (and there are a LOT!). The piano sound is fantastic, similar to a Yamaha I played in a local recording studio many years ago. That great Yamaha piano low register clarity and the crisp high register that are Yamaha trademarks are there, with options for closed top, or two open positions and room ambience settings. It’s almost worth it just for that piano sound. The interface is also well done and better than the Privia. The action feels really good for weighted key action, but as with almost all keyboards it’s not 100% the same as an acoustic action.The only down side is the weight of the keyboard makes it a little less easy to take to gigs. I remember taking Rhodes cabinets years ago and this is nothing like that, so it’s only a minor issue for those that have lugged heavier gear in the past. But if you’re looking for a keyboard to easily pickup and go, you might want to compare the weight of this with the weight of other keyboards.All in all, it’s definitely one of the best in this price range, and better than some more expensive ones as well (my Casio was $400-$500 more and it didn’t have any better features, except the internal multitrack recording, which you can still do on here with MIDI, but I use my home studio for that anyway).Side note … if you own a cat, get waterproof covers for when you’re not playing. That’s how I lost my expensive Casio. Ugh!

The Yamaha DGX-670B is far and away the best piano keyboard I have ever played. Get a good quality heavy duty stand because it's kind of heavy and it's best to have a friend around to help lift it but that just makes it feel extremely stable to play. The sound is the best part and is fantastic... especially the grand piano. The controls are intuitive and very easy to navigate.

This is a great digital piano. It sounds good and has lot of function. The keys fell very natural and good. I play it very day. Only thing is it is just too heavy. I wish there was a 61-key and rechargeable version of this product.

Great keyboard. Has so many features and piano sounds are so realistic. Great for beginners and professionals. Weighted keys make it feel like an acoustic piano. Only small complaint I have but really isn't a complaint, is that the volume isn't as loud as I thought it would be. Wish max volume was a little louder, but still a fantastic keyboard.

the best digital piano for the money

Sound quality is fantastic. It's bigger than the regular keyboard though. It will be best to get it with a stand. It's got some weight to it too.

This is the fourth Yamaha keyboard I've owned, a YPG, a P series, a MOX, and now this DGX670b. The build quality is better than any of them and it is in tune right to the bottom end. The build on the MOX was much poorer and the tone quality was poor. The piano sample on this one is very believable. I would have chosen a little less vibrato in the horn samples. Exaggerated it can sound like a billy goat. A few instructional videos would have been nice. I'm happy with it overall.

I like the keyboard. I bought it for my son. He likes it
