I tried and tried and cannot tell them apart. With and without amp, lossless and MP3.
Uven using splitter and put the same side of each in my ears and I still can't tell them apart.
Is there any cosmetic difference I can check that BLOX didn't mistakely sent me an M2C?
I checked with BLOX. (Great customer service and quick resonse btw)
They told me the sonic difference between 'new' M2C and ANV3 should be obvious, but they can't comment on 'old' M2C because they don't have them at hand.
There is a way to distinguish the ANV and M2C by seeing how deep the grey(back)part goes into the black(front) part.
The Anv3 will go in a tiny bit deeper because of the thinner driver.
So I guess the explanation I came up with is the old M2C is tuned very similarly to the ANV3 and my ears or my gears aren't sensitive enough to tell the differences.
But in the end, they both sound amazing anyway so...
