Extremely impressed by the imaging capabilities, the bass quality and the overall resolution/detail.

The sound is incredible, the bass line and the sub bass will literally make you jump on the sofa,you will find bass you didn't know existed in your music.These are the positive things, now we come to the less positive ones, the headband is the worst thing,heavy, ugly and badly adjustable. The cable, too long and of low quality. But the really unbearable thing is to choose UPS as a partner, it should be the top but it is literally the worst possible choice.
luckily the sound is great

They sound really really good for their price but the headband is something they must fix, it's just fine really..

Sound wise, there is very little to fault these. My first set of planar headphones and they compare favourably with my Sennheiser HD660S. They may be low impedance but these phones benefit from an amp. Even my Ifi Zen Dac V2 benefited from another amplification stage. Build quality isn't the best, my first set were returned as they had some build issues. They certainly don't feel the same quality as my other headphones (Senns, Grado and AKG). They are comfortable enough, but they are big, and don't clamp that tightly so are for home use only. Even with moving your head around they don't feel too stable. Also for closed back they do leak sound into the environment a fair bit. I'm giving them a 5/5 based on the sound quality and price. Would love to see the M1570C over in Europe, now I have a taste for planars.

Sounds amazing, undistorted and big, vocals are special and very serious about, bass is big and broad, mids are very nice but some more expensive headphones separates instruments better, treble is the weak point (I'm a treble man but at least is very smooth), well played with THX AAA 887 and Gustard X16 plays very nice. I do wonder how much times will be better the M1570c as soon as they drop in Europe :)
Great from monoprice! Actually i liked it more than Audeze LCD-XC 2021 even if that's it a bit more detailed, guess the wood cups on M1060c makes the difference, also i prefer it to HE6seV2. That's say a lot! 0 distorsion unlike many headphones, and, if they will make an HE1000V2 type of headphones without distortion i'm done.
