TRUTHEAR Hexa Hybird in-Ear Headphone

First, the fit and build: box and accessoires are basically the same as on the Zero, which is completely fine, but nothing exceptional. The IEM earpieces themselves are rather sleek, slightly translucent from the ear side, but feel overall well made and are quite light. They also have a somewhat thick and quite long nozzle, which made me slightly worried about the fit (the Zero was pretty close to not fitting me properly). However, thanks to the long nozzle, they protrude from the ear canal significantly, and I had no issues using them. I use the included tips (medium size, small bore), since in contrast to on the Zero, they provide a secure fit this time. Most important however is the sound. And well, I have no hesitation to call them neutral. They sound very clean, with very clear mids and a small subbass boost that provides proper impact to make drums sound good. There is absolutely no bass bloat or mud found here, making even fast songs sound clear and not congested. Imaging and soundstage are IEM-typical. However, there is one thing of note and criticism: similar to the Zero (though less prominent and without the harsh vocals), there is what I'd consider a slight, noticeable treble peak somewhere. Cymbals can have just a hint of added sharpness that makes them stand out in the mix a bit. It reminds me slightly of the treble peak on my DT 1990 (I assume it is at a similar frequency), though it is far, far less prominent here and does not cause actual issues. It does make them lean towards a metallic timbre though, but not enough to make the sound unnatural. That kind of thing seems to be very subjective, so YMMV. Overall, I can confidently recommend those to everyone who is interested in a neutral, clean sound within this price range. If what you are looking for is an energetic, or fun, or relaxing sound however, they are not for you. The Titan S has some added sparkle and energy, but still provides similarly clean bass and mids, while the Aria has a more relaxing, bassy-and-fun sound at the cost of lacking the clarity and natural sound.
