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.

I have the same problem but for me it starts after about 45 minutes of contineuous listening. Using the smallest size of included tips.

I don’t think it will handle extreme EQ profiles, but small nips and tucks here and there: like upping the bass and mellowing the treble by a bit.
