I assume you have plans to review the his other new one too.
HBB has three in the pipe that we know of right now.
Olina SE
QKZ x HBB - $20 for something that has more bass than the ZEX or CRA, and as much sub-bass as the FHE. The smoother treble, and the 5k cut makes it look an easy rec, at least for bargain hunters.
HBB Maka - The $35 dollar replacement / upgrade to the Mele. At this point we don’t know much, but it looks nice, and given that Mele is a favorite for many of us, I am guessing it will be popular.
But what I did was put a micropore tape air vent between the nozzle and eartip, to bring down the bass level and clean up the mid-bass bloat, then taped the front vent to put the sub-bass back in.
The bass tightens up and is cleaner but still very high quantity, but the little space between the eartip and nozzle gives an added effect of expanding the soundstage a lot and improving technicalities like imaging and layering.
After the mod, it’s in the ballpark of Kai. It’s still V-shaped, and has a huskier, thicker mid-bass/low-mids than Kai, where I’d say Kai still has a little better tonality and timbre. But Rosefinch is a more dynamic replay in terms of soundstage and layering/imaging.
