Truthear IEMs

[Matias]

Funny tuning. It has the more linear upper bass and lower mids, but also significant less shout.

That will definitely sound "muddy" and is severely lacking in the upper regions. Hard pass!

I expected Pure to me more of a gradual tweak to Hexa's tuning, but the difference seems quite large. Some people complain about Hexa's lean bass, but it me its lean bass is a big perk. I can listen for longer on Hexa without ear fatigue creeping in like it does on bassier sets: https://en.wikipedia.org/wiki/Listener_fatigue#Vibration

Not a fan of the chassis tbh.

a couple graphs for Truthear PURE:

I like the design, but the graph seems not very promising to me. And to be honest, each IEM is, besides built, design, material and fit and all this, just from the sound perspective, an EQed version of any other (ceteris paribus). That is why I really promised myself to not buy any additional one anymore in the future.
The PURE has even less ear gain than the EPZ P50, which was the last one I bought and quite like. It is basically the Hexa with a HSQ at 600 Hz, Gain -1,5 dB, Q 1 filter.

Quite the opposite for me. I use AZLA SednaEarfit Origin tips with every IEM, as they give me the best fit and seal. In my experience, the Hexa has very extended sub-bass, although the bass isn’t the punchiest. The real issue, however, is the peaks in the upper mids and treble, which I can't fully eliminate even with EQ. That’s why I’ve put them back in storage. It’s a shame, because they’re incredibly comfortable.

just tried to quickly eq 7Hz Zero to Pure curve via Hangout squig, end the overall result is, as expected, too dark for my taste, especially when A\B with the Zero bright stock response, that i like so much.
Surely suited for relaxed long listening sessions and for anyone extremely sensitive in the upper range, clearly I'm judging on an approximation but not going to try them.

Got the Truthear Pure delivered to me yesterday, it's a huge disappointment for me, with factory tips, they sounded dark and muddy, with treble sounded thin & distorted in some strange way (typical BA driver sound? I don't have better way to describe it rather than "bit-crushed treble"), basically anything you don't want in a hybrid IEM these days, it's completely different from how the HEXA/Nova/Zero performs, I don't think this thing will sell well, decided to keep my Zero & Nova and put this one on the second hand market (Since in China they don't allow users to return used earphones).

(They do wear more comfortably though, the smaller nozzle tube feels better than the Zero one.)

At this point I think I'm one of the only ones who'll no longer buy Truthear with their switch to smaller nozzles. I appear to have cavenous earholes, especially the right, and wider nozzled Truthear IEMs, along with an XL tip acually gave a good seal.

The bigger nozzle size has been a selling point for me too. Secure fit like I haven't experienced with other IEMs.

I know it's a bit gheto solution, but using teflon tape over the nozzle and snugging in the silicone tips helps overcome this problem. I'm getting very good seal even on small nozzle IEMs.

I just order a set of the Pure's. Тhey have very mixed reviews currently, either praised or criticised. Anyway, I doubt you’ll have trouble EQing them to your taste. With a current price of 76$, they are a quite good deal from Shenzhenaudio.

Earlier this year, I bought the Zero :RED after reading all the glowing reviews, but I must say I was a bit disappointed with the overall tuning. I find them a bit bright-sounding, and too muddy-sounding with the impedance adapter.

Maybe this Harman curve for headphones isn’t for me, but I had hoped for headphones that didn't need any EQ adjustments and would work for me out of the box.

I also hear a small channel imbalance, so things that are meant to be in the dead center of the mix are slightly off-center to the right. This has never been the case with other headphones I've owned.

The things I do like about them is the impressively low level of distortion, that is clearly heard and makes the bass very clean and articulated. And they are also quite comfortable to wear.

I am listening to the Truthear Pure right now. I must say they are voiced differently than anything that I’ve heard before. They do lean warm, close to being dark but not quite there. Details shine through despite the warm presentation. They are definitely non-fatiguing. I’m not sure if I like them or not.

Now that I’ve had some hours with the Pure its sound profile has grown on me. Is it my ears or the Pure that has changed with hours of use?

The Pure is my first IEM (besides Apple EarBuds). I am comparing its sound profile with AKG K371 headphones. My first impression was that the Pure was very warm, almost dark sounding. That has changed. I find now that it follows the sound profile very closly to the K371with an exception.

The Pure is warm but not close to being dark. In fact starting from the midrange on up there are only small differences between the K371 and the Pure. The sub-bass on the K371is much more prominent. Kick drums are have more thump, sub-bass notes are stronger and have some bloom.

The sub-bass on the Pure is weaker. Some sub-bass notes on Go Go Penguins’ WAVE DECAY are barely audible while the K371 renders them strongly. The mid-range on the K371 gives an impression of some sweetness where the Pure is just a bit drier. I noticed a small difference in the treble between the two. Snare drum attacks were a little more biting with the K371. Glare in the upper mid-range was completely absent in both. My ears are good but not exceptional.

One YouTube reviewer heard some harshness in the treble of the Pure with the wider grey tips. His preference was for the darker black narrow tips. I tried both tips and heard no difference in the treble.

My conclusion is that the Pure is a nice IEM for $90. It’s not perfect but it’s not offensive. Build quality is nice. The cable is pliable and connectors are well made. I think reports that its sound profile is too dark are over blown. I may have been influenced by those reviews when I related my initial impressions. The K371 sells for $120 on Amazon. I like the performance of the K371more than the Pure. The K371 is worth the extra $30.

After 3 days listening to the Pure's all day at work i'm quite pleased with them. Very good set for long sessions even on very high volume levels, treble extention is nice too. Had to bring down that hump at around 200hz to the IEF target and this has fixed the "dark" profile people are mentioning on the reviews.

Not really sure why they tunned it like that, my uneducated guess is by looking at Hexas graphs, they have't change the dynamic driver or the sound tubes just bumped the impedance on the dynamic driver (maybe the first BA, also?). Cost cutting? Probably.

With Angelears AE100 tips the sound stage becomes even wider than the standard wide bore tips. Keep in mind my comparisons are coming from Chu II's and Blue 2's so my view is quite limited. Pure's sound quite better than both, but the Blue's are a bit special IEM which is tunned for people who like foam tips, which i dislike quite a lot.

Nice review. Obviously we have different ears. I was aware of 200hz hump from reviews and graphs. During the first hour of listening my initial response was that the sound profile was very warm, almost dark. But after many hours of listening I feel something has changed, either my ears or the Pure. For me, it’s fine now, no eq needed.

I kinda can confirm the same, that's why on the first day I neither touched the tips nor the EQ, I think there is "natural tunning" that's happens in our heads, could be that with more experience/hours and listening to more IEMs this to happen quicker or instantaneously.

I listen to very wide variety of music ( basically anything ) and for EDM and Hip-Hop the bass and rumble was too much, but for Rock and Jazz for instance it was quite good and pleasant, it goes down to taste to be honest. For myself I found some middle ground so I can switch between genres without much trade-offs.

One more thing I can add about Pure, comparing them directly to the Chu's is that ( excuse my lack of sound describing vocabulary) the level of clarity, detail retrieval, speed of bass is on another level. Curious on personal level where the ceiling is, what is the perceivable difference of quality and fidelity ( taking into account that the most of the nuances and tastes can be EQed), obviously diminishing returns should start somewhere on this level of the Pure's.

Been using the Pure for a week and agree they aren't that dark. I think they've accomplished a generally neutral sound without the anemia that you get with other neutral IEMs such as blessing 3. On these though I miss the bass shelf of the Nova, so definitely trade offs involved.

So, you prefer a warmer tuning. That doesn't make brighter IEMs universally worse. There's plenty of knowledge, such as the harmonic series and frequency masking, that relates to perceived fidelity degradations with overly warm spectral tilts. Not trying to be contradictory or start a debate, just providing balance to the polarized framing you presented here.
