Had the chance to audition two of the more "hyped" IEMs in the current market: Truthear Hexa, and AFUL Performer 5.
FIrst up: the Hexa.
This one has a truly impressive spec-sheet given the modest price tag. A quad-driver hybrid setup is rare under the USD$100 mark, and Truthear achieves that. More importantly, they manage to make it all sound somewhat coherent, which is not a simple task.
The build is nice, stock cable is decent, and comfort is good. Then we get to the sound.
The bass is somewhat soft and lacks the dynamism I expect from a... dynamic driver. The mids are inoffensive, so is the treble, but all of it sounds overdampened. Transients are on the mushier side of things, and stage feels congested. Imaging is also not a strong suite.
For the asking price, not bad at all, but not as "groundbreaking" as some of the reviews made them to be.
Next: AFUL Performer 5.
I am not gonna bother with the low-hanging fruit of a pun involving the name, so let's get straight to the build and comfort. Build is good, the resin shell is high quality and while the artwork is nothing spectacular, I think the gold letterings mesh well with the faceplate design. Comfort can be a bit of a mixed bag as the shell is quite large. It worked for me, but for smaller ear canals might not be the case.
As for the sound, this is a five-driver hybrid with 4BA and 1DD. Sadly, the bass does not sound like a good DD bass should. The sub bass has decent rumble but that's about it. Mid-bass sounds hollow. Vocals, on the other hand, are very good. Male vocals could be a bit fuller but the female vocals are as good as it gets in this price. No shoutiness and well articulated. Strings sounded decent as well.
Staging is intimate. Imaging was mostly left and right. Macrodynamic punch felt lacking due to the hollowness in the mid-bass.
To summarize: the Performer5 are not "bad" per se, and with vocal-centric tracks I find them fairly good. But I think these aren't very versatile, so depending on genres, you may find the Performer 5 lacking.
As for the Hexa, not bad at all, but again - the presentation is flat and does not quite engage as much as the Dunu Kima or Final E3000. Your mileage may vary depending on source and tracks of course.
