Finally getting around to posting a review of these beauties, so here goes.
I've been using these as my JOAT cans for work, music, and on the go listening. Their tank like build quality and price really makes me not even think twice about throwing them about or mistreating them. So far no notable wear or scratches, and no loose parts. Only issues I've had so far is the earpads can be a bit stiff on first wear, and it feels as if the foam takes a few minutes to adjust to my head. They aren't perfect with glasses to be honest, but I'd say a decent bit better than the Ultrasone HFI-580s. Happily they offer some isolation from ambient noises, though the overly long cable can make it awkward when on the go.
Sound wise they are quite on par for ~70 dollar headphones. Overall I haven't found a genre that sounds horrid on these, and sound decent out of various devices I have tried, so I have qualm with taking these on the go. I'd describe the sound as bass heavy, mids sound just fine to me, but the highs can get a bit harsh depending on the music, so your mileage may vary. I wouldn't call em laid back by an stretch of imagination. I find myself taking them off after a few hours of use thanks to the combination of harsh-esque highs, stiff earpads, and some clamping force.
Overall I consider these fairly great headphones for the price, and wouldn't dissuade anyone from buying them.

Difference is that m40x has lower impedance, less windings of the coil. Gets louder.
Clearly it is a feature and driver difference – 30x and 20x have same specs, but 40x and 50x share same specs. The sound is different but I think 30x suits my needs. I will use these for many years.
