Truthear x Crinacle Zero:RED IEM Review

[jaguone]

I have custom molded silicon tips for another iem, hopefully I can modify them for the REDs. Always had problems to get a proper fit/seal.

Don't use (good) earphones so I have 2 concerns about this and IEMs in general:
1. Is the IEM too large and thus hits people's ears?
2. After proper seal, is it possible to hear one's breathing? My cheap earphones do.

I hear my own breathing a bit, but once music is playing, it disappears. It’s never bothered me. As for fit, I find the original zero fits me very comfortably (I use the large tips for the best seal). That obviously won’t be the case for everyone, so it’s hard to answer that question. At least the cost of giving them a try is minimal.

Do not worry, he is not suggesting you can use this IEM as an offensive weapon.

What would it even mean, maybe In-Ear Missile?

Improvised electronic missile

watched the video and Crin was so entertaining I went to Shenzenaudio and bought a pair.

Me too. I already own the blues, but I like the colour of the reds and fancy seeing if I can tell the difference between the reds and blues

Hmmm

It is going to be an interesting experiment isn't it. If the graphs are to be trusted, we have two diffrent IEMs with almost identical FR. I am quite curious to hear how they are going to sound comparatively, not just tonality wise but also things like imaging, separation etc. and whether I can learn anything from this experiment.

I've worked in pro audio for 40 years. It's unlikely I've ever heard a transducer with distortion that low before.

you probably woulnd't hear some higher distrotion anyway. You can be honest with yourself by taking: https://www.klippel.de/listeningtest/

also moondrop arias and some other iem have as low, if not even lower distortion plus very similar frequency response.

Let’s all try and stay on topic. Reminder that this is an Official Review Thread. Please take off topic conversation to a separate thread or PM.

Thank you for your cooperation and understanding.

Couldn't resist and ordered them on the spot for €55, to be delivered June 3rd to 8th. We shall see (hear) how they compare to my old Ultimate Ears UA5 (€150 back then) ...

Curious how people use wired 3.5mm IEM these days given almost everything has gone wireless. I have old Sandisk Sansa mp3 players I use on flights, but without noise cancelling, I don't see a good use for IEMs on flights.

I am tempted to buy these, but just don't see a use case.

 

[Soria Moria]

I quite like how these look.

I own 2 x 7Hz Salnotes Zero and still I ordered the Red.

These are somewhat large, if that is a concern, try the 7Hz Salnotes Zero, which are smaller and have almost the same FR. As for breathing, yes, probably.

Nice IEM, and indeed impressively low distortion, but I wonder if the difference in distortion between Red & Zero is really going to be noticeable, especially as the bass didn't really need much or any boosting in the Zero. I can't really imagine bass sounding any cleaner than the Zero when I tried it when I first bought it (I don't really use IEM's so basically don't use the Zero anymore).

Wow, Sansa… that’s a blast from the past. Good on you keeping that old tech alive! I prefer wired, and almost never fly, so if use on an airplane is your bar, I get it. I‘d prefer wireless, over-ear phones with noise canceling in that case.

Hmmm

Anyone dare to make a guess on what will be the common impression between these similarly measuring sets?

All I can say is that the Truthear and Moondrop(same engineers) DD sets I've owned had a rather consistent treble. The 7Hz Zero had a different kind of treble, in a way I didn't expect when looking at the graphs before purchasing.

That’s going to be my first test, once I get mine.

Bought !!!!

Waiting for the Golden version...

Maybe Crinacle was so delighted by the tuning developed by himself for the 7 Hz that he wanted a model with his name on it officially in the market, generating the Red

Jokes aside, there will be more difference for sure, given the technical differences (2DD vs 1 DD, membrane material, ecc...) plus, as I noted before, looking at the new measurements he made with the B&K system the 7Hz seems to have a high peak at 13k that Red doesn't show, so a comparison would be of great interest.
