TRUTHEAR x Crinacle Zero IEM Review

[bilifen]

Here's a little new problem that I got with the Zero Blue:
The Spinfit CP155 (M) I got close to... 2(?!?!) years ago somtimes get stuck in my ears. So far I could always get them out but I'm kinda scared they could get stuck in a position where I would need help to remove them.
Does someone have an Idea how to fix this (maybe without buying another Spinfit Pair because they are so expensive haha)?
I had some ideas like putting a small O-ring somewhere maybe over the IEM stem, maybe over the stem of the earrtips, but didn't try anything with this.

So instead of expensive IEMs, the business model is "let's get them to upgrade from cheap IEM to improved cheap IEM".

I'll skip the 2 and wait for the 3.

Good to know. (I am/will still orient myself after your opinion, still very happy with the EQ you put together.)
Anything new that is looking interesting as an upgrade option or did still nothing change in that?

When removing iem’s pull down on your earlobe as this will break the seal, makes them far easier to remove

Ok, will try to implement this, thank you.

Put the tips in hot water . They will likely shrink a little

Going to try the earlobe thing first and see how it helps, worrying that the fit wont be as good when they shrink, which is good right now, they wouldn't be getting stuck if the fit wouldn't be good, right? Still, thank you, going to prolly do that if the other thing doesn't work out.

Still not a big fan of these after almost 2 years of trying. They lack detail by default and when you play with the EQ to "add it back" the result is unpleasant, sibilant and harsh. Thank God they were not expensive.
If you wonder, the less expensive CHU II sounds clean in the same areas. Pristine actually. Bass is also better, especially after a bit of EQ. Should I mention the CHU II is smaller, easier to fit (Comply foam tips for me) and consequently significantly more comfortable to wear than these Zero Blue?

I got burned incredibly hard on the original chu, so I would never get them/ the successor again. Completely tarnished anything that will be a chu.

(Almost stopped going the IEM route because of them.)

Curious what exactly will change between the Red and the original Blue.

Basically a slightly more u-shaped Zero:Red

Guess I shouldn't write messages here when im sick, I even reacted to the conversation about the Zero Blue 2...

Blue 2 incoming.

You know what, after watching the part about the Zero Blue 2, maybe I'm sidegrading.
The mic cable would be great, people always hate me in calls with my qudelix 5k setup, every time I move, they hear loud noises.

Kinda confused on the nozzle size, crinacle said 6.0mm so that's with the lip then?

(Getting the info about the speakers was also cool, interested in them)

Zero Blue 2 is out:

"I Made the Best Budget Iem... Again"

64.99$

Sounds nice, I wonder if the nozzle going from 6.8mm to 6.2mm will be noticeable, because boy is the original unpleasant to my ear canals.

Is anything known about the mic cable? I use the Reds during work and usually have to switch to my headset for calls, I'd prefer to just keep them in the whole time instead. Does the mic cable have noise suppression, what's the sound quality, could you even use it outside with wind, etc.?

 

[mc.god]

As Crin says in the video they are tuned with foam tips in mind, but honestly with silicone tips the treble response is really nothing to write home about...

I was not much interested from start (I'm more for the Red tuning), and since I don't like foam tips it becomes a definitive no for me.

 

[Dazerdoreal]

I would like to add two potential fair warnings:
- The pinna gain peaks later than usual, at like 4k: https://graph.hangout.audio/iem/711/?share=Harman_IE_2019_v2_Target,BLUE2_S37_Foam,Zero_TE_S2
While this might be an interesting coloration, it might turn out to be a less harman-ish timbre.
- This thing really seems to depend a lot on output impedance. I would not be surprised that if used with some 1 Ohm source it already has significantly more bass than graphed here.

The Truthhear Zeros are ridiculous for the price. I can't believe how good they sound and how much separation there is for being low-cost dual drivers. I am floored at how good they sound, and happy that I have a pair of IEMs that I can trust out of the box.

I also think the HF boost is pretty close to just right in these - those who complained about the top end not being sparkly enough - it might be an idea to listen to an incredible set of speakers at the listening position and compare that to your IEM preferences. I prefer a smooth top end that is present and gently sparkles.

On tracks like Daft Punk's Get Lucky I can hear the brightness, and in Leoniden's L.O.V.E. I can feel the grit of the bass distortion and thickness of the low mids. In Bethel Music's "Homecoming - Live", the smooth, extremely balanced mix is a pleasure to hear.

I find these IEMs strike a tricky balance - out of the box they sound great with very little to complain about other than "I wish they had even more separation" ... which isn't really a complaint at this price point. But when tuned to compensate for the little imperfections, they sound positively wonderful.

Forcing these to the B&K curve produces a much more pleasing and neutral top end. Harman is fine, but as Crinacle rightly complains, it's "shouty". But these are correct tonality as a Harman curve-compliant IEM goes. As such, these are probably the last pair of headphones that I would purchase with the Harman curve in mind.

The thing I'd differentiate is "correct tonality" as it relates to a Harman curve vs "clinical tonality"

In perceptual terms, clinical tonality is the perception of a flat response from 20hz to 1khz, followed by a gentle roll-off to -6 at 20khz. The Harman curve is perceptually flat up to 1khz, but then increases intensity between 1-5khz before rolling off to infinity at 20khz. Mastering engineers will immediately recognize this as wrong.

not everyone needs to hear music with the same clinical accuracy as a mastering engineer, but I can say as someone who takes great caution to protect my hearing that clinical tonality is a gift that is possible to achieve at low cost, and the zeros come closer to achieving this possibility than anything else I've tried in the sub $500 price range to date (when tuned).

Just received the Zero:BLUE2. Tested and compared intensively to 7Hz Zero 2. No sound difference worth mentioning, but practical differences: more expensive, more big (can not lie with head sideways on a pillow), different way/angle when placed in the ear (might be an advantage for some, disadvantage for others).

As a bass head I was astonished that the original Zero 2 can playback 20 Hz at much higher volume (ear deafening) than the Zero:BLUE2, which starts to audibly distort much earlier. And I never hear bass modulation with the Zero 2, so the BLUE's dual driver system is of no advantage for me. Nevertheless - perfectly sounding for under 100 bucks, so again a very good IEM, it seems.
