Nah, the extreme outward curving angle of the nozzle is something that will work for a cable down fir with probably less than 10% of the people who own a b2, which means for a cable down use a lot of people will have to go with a very shallow insertion and it's pretty much like using a shallow insertion with an ety iem - it's not at its best sound at all. At any rate, the angle is too steep for such a long nozzle and that's why the dba02 mk2 is a lot better in this regard. ANd brainwavz didn't really tune the B2 - it's an OEM design - not their own.
Brainwavz did tune B2 - they chose a different filter than the one used in DBA02.
I can't see on your picture - are you switching channels? if you are not, you are going against the structure of the ear:
The "acoustic meatus" goes towards the front, not back.
And if you are switching channels - then it should be clear to you that Brainwavz didn't mean for B2 to be worn that way, or they would have switched the "L" and "R" markers.
