Comfort: Comfort isn’t perfect, it doesn’t make much contact with the surface area inside your ear which could impair the fit for some people but the fit is stable enough that it won't fall out on its own and for me, the lack of conformity to my ear hasn’t once bothered me (I almost forget they’re in)

They come with many tip choices (Three large bore, three small bore and one set of foams) I have found these work excellent and have caused zero irritation, however, the foams do slightly affect the imaging and upper air frequencies, I have decided to use the wide bore medium sized tip for all of my thoughts.

Build quality: The build quality of the Hexa is excellent, they’re topped with a very subdued matte black aluminium faceplate bearing only the Truthear logo on the right side and nothing on the left, their overall personality is mainly comprised of their polygonal shape and the single phillips head screw visible on the faceplate, the underside is a very slick and high quality, dense smoked transparent resin, however, this quickly shows ear grease and could use a clean every few uses.

The cable is a relatively flexible braided PVC type plastic with minimal microphonics, it bears the truth ear logo on the splitter and has a nice chin slider, the connection is terminated in a 90° angle 3.5mm jack.

Sound:

Sound signature: (Warmish neutral with slightly recessed upper mids)

Treble: Treble is reasonably controlled, it never gets too intense or harsh however live cymbals have a sort of subtle washy gritty characteristic to them at times, but you can manage to get some great detail out of these IEMS with electronic tracks with assorted plucks and arpeggiator sequences.

Mid Range: Mids are a touch on the thick side meaning instruments like pianos still have their weight and body but sound a little bit too much on the warm side which heavily impacts their timbre and quality. Upper mids are on the recessed side meaning unless the song has present vocals they might get a little lost in the mix and get a touch hazy, Timbre is leaning towards slightly artificial. Still, it’s to be expected for the driver setup this iem uses especially at the price tag.

Bass: I’m going to start with the mid-bass as it’s a little too thick sounding for my taste, it kind of messes with the tonality of the mids (as mentioned in that section) and makes them sound a little congested as a result, the response is tight and reasonably fast with a nice thump on tap. Sub bass is done tastefully but you miss out on some really low rumble with these in-ears, which some may feel the need to EQ to their preference.

Technicals: (Negate this bit because they have inverted polarity)

First thing, the imaging, it’s quite outstanding for an iem, you can somewhat pinpoint where sounds are coming from but it doesn’t stand out like a sore thumb if you’re not paying attention, separation and layering ability is average, you can pick out different instruments but they still blend together a little and become a touch congested on some tracks, stage or what little of it there is can be confined to inside your head yet still has a little bit of room to breathe but it isn’t what I would call breathtaking.

Dynamics are presented quite faithfully, quiet sounds are quiet and loud sounds are loud, macro dynamics are very good there’s a very discernible dynamic change between passages and build-ups to crescendos. Micro dynamics are also reasonable you can pick out sudden changes and anomalies in your music with ease.

Resolution is good for the price, fine details can be heard and you feel at ease knowing you’re getting some pretty great detail at the price point of $79.99

Overall: I think at this price point you're getting a lovely little package, a well-built iem with everything you could ask for on a budget with an attractive and subtle appearance; its sharp contours and industrial paint job makes it quite an appealing buy, matched with the exceptional sound quality and I’d say it’s a no brainer!
