The Dual Dynamic Drivers on the Blessing 3 are incredibly capable. Such a shame that they're not being put to good use, since the IEMs can actually handle a monstrous amount of additional sub bass, without any perceivable distortion (around an additional 6db of sub bass). Just fiddling around with wavelet, I was actually surprised the IEM could handle the default "bass boost" preset without any limiter. That's a bass shelf of around +6db on the sub bass, and absolutely no changes elsewhere. Why are they designing the drivers this way when they're not gunning for bassheads ? With this tuning, the Blessing 3 can outperform many of the bass focused IEMs in delivering clean and impactful bass, and yet the default tuning is the most conservative I have ever seen for a product of this class. All that additional bass is handled so beautifully on the Blessing 3 that it sounds like a completely different IEM. It is clean, rumbly, and doesn't cause excessive bloat on the other frequencies. Side note: for some reason, only using the IEMs wired and in legacy mode on wavelet produces distortion free sound. Enhanced session detection/running over bluetooth LDAC destroys bass completely.
Other than bass, is there any advantage to dual opposed 10mm drivers ? I know in the B3 they are responsible for low end but I have heard a similar low end in single DD setups. They must be doing something to be present, because the only other possible explanation I can think of is that they exist for the Blessing 3 dusk. I have seen a few tuned IEMs have very modest EQ enhancements like an additional 3 db bass, not extreme like 6db (except HBB & FatFreq) since it would not be to everyone's taste.
