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.
Yup, I have it paired with the Spring Tips and it takes EQing from my Qudelix 5K like a champ. Not sure why these got such a luke-warm reception overall compared to other IEMs, they are highly competent in all areas and respond very well to EQ. Perhaps people were expecting more. I never owned the B2, but most people seem to agree that the B3 is an improvement, but not too big of an improvement.
Personally i think its a big improvement especially on the mid, rather heavily lean on Female vocal like b2 the b3 can now also do male vocal which is open the possibilities to many song and genre.
