I think somewhere earlier in this thread there was a link to MW07 tear-up that showed that M&D used the most "dumb" Qualcomm CSR chip that has inline DAC and non-upgradeable firmware or EQ (similar to RHA). I guess they went for it not so much because it's cheaper, but because this SoC is smaller and needs less juice. This leaves larger acoustic chamber to shape and more battery to drive huge, by TW standards, 10 mm custom dynamic driver with a stiff beryllium diaphragm. Me figures that M&D, like their Grado neighbors in Brooklyn, is first and foremost outfit with hi-fi acoustic expertise, not an electronic one. So they went the way to make good sound how they know best. I would argue that even if they skimped on something with discounted Best Buy version it must be batteries and/or left/right drivers matched with less tolerance. Just my speculations though, take it easy.Perhaps, although the chipset should be the same, as would the software, unless there were some tweaks in between build runs. Having been in manufacturing in my pre-professional days, we would use assembly parts that were not always exactly the same or from the same supplier. The only way to be sure is to disassemble 2 pairs of MW07s, but who the F is going to do that?!
