Hey everyone! I'd like to ask for your help regarding these measurements. I've recently started trying to play around with EQ. I've seen graphs of the same IEMs from two measurement rigs. Since I'm tuning the bass on my Truthear Hexa, I've noticed this weird divot in the bass on B&K measurements.

Can any of you enlighten me:

1. As to what causes this

2. Why it's absent in the IEC 711

3. Does this reflect as to what actually happens in our ears

4. How do I go about EQing this region

I've also read this but might be too stupid to extrapolate the answer to my question from it, that is if this article is related to any of my questions at all.

I've seen two other posts here in the past two days that were a bit lukewarm towards the Truthear Hexa, so I'm here to pile on the constant glazing once more. I got my Hexa yesterday, and I finally realize why y'all have been hyping up this IEM for the past few years.

My Context: My audio experience has been limited to ultra-budget stuff. I own the Moondrop Lan, GK Kunten, NiceHCK EB2S Pro, Koss Porta Pro, KSC75, Moondrop Old fashioned, a bunch of KZs, and some Bluetooth gear from FiiO and Moondrop. I also own some cheap, jerry-rigged shelf speakers.

The Step Up: The Truthear Hexa absolutely blew away everything I own. For a while, it felt like something was always missing with my technicalities; my music always felt smeared, and certain sounds just didn't cut through the mix. Like many, I was introduced to the scene by a budget chi-fi company and was entranced by the marketing that "more drivers = better performance." Buying the Moondrop Lan three years ago disproved that myth for me, and while I loved the Lan, I still wanted more.

Enter the Hexa. Upon first listen, the first thing that popped into my head was: this set sounds right. It sounds correct. It is incredibly controlled and clean, but what really blew me away was its performance on busy tracks. Stuff like Yoasobi’s "Idol"—despite being compressed as hell—sounds better because everything cuts through the wall of sound. Now I know why some shady manufacturers keep shoving drivers in their budget iems for marketing purposes, it turns out, when done properly, it can actually do wonders

Bass and Treble: Because it handled chaotic tracks so well, I tested it with well-produced catalogs from Michael Jackson and Daft Punk. It sounded even more amazing. Despite the common gripes with the Hexa's bass, the basslines on the Daft Punk tracks were noticeably tighter. It wasn't just a blob anymore; I could actually hear the notes and the texture.

Another complaint I've seen is its bright-leaning tuning. Admittedly, I did notice a very small tinge of scratchiness in the treble, but I understand that this is the tradeoff required to achieve the Hexa's best traits: its detail, separation, and imaging.

Conclusion: Everything sounds clear and separated. I can easily pick out a sound and keep track of where it is relative to the rest of the mix without it getting drowned out. This is alone could be the sole reason for getting the hexa. If you are still snooping around the sub 80 usd price range for a technical set, I recommend taking a leap to the hexa to save you some money (if you are fan of the kind of tuning). At this point, I'm fully on the hype train. I understand it now.
