@amirm Which tips did you use for measuring? They provided a couple of variations for the silicone tips with different nozzle sizes and never specified which one complied to the Harman curve. Also curious about what one or the other does to the sound.
I think the point of ear tips is to adapt to your ear canal shape, to your physiognomy. It’s not about modulating the frequency response, it’s about getting the perfect fit. I don’t see how which tips was measured would help since the fake ear of the measuring head is not your ear. No?

Ahh, finally a great earphone that can be used with my iPhone and it’s dongle on the go without eq! Ordered on Aliexpress.

We need to test the new Apple AirPods Pro when they start selling soon. The sound is claimed to be improved, and noise cancellation is a great feature.

Yes and no. If I want more highs, it's one of the silicone tips. If I want to tame the highs, it's foam. There are some that sit in between and are balanced. The different sizes help with your ear fit.

Ha, ok, I was thinking size, not choice of material. My IEMs only came with Silicone. What’s « in between » silicon and foam?

My Fiio came with two different silicone tips, one red and one black. One sounds a little bit brighter than the other. I think that the hole size is a little bit different but I don't have them here to check at the moment.

This is a review, listening tests and measurements of the Truthear Crinacle Zero IEM review. It was sent to me by @crinacle as he has been a consultant on the project. It costs US $50.
View attachment 230789

I like that it has a bit of "bling" but not too much. The cord is just the right length for me (many IEMs are too short for my use). It is super flexible with very little microphonics. You get two sets of silicone pads in three different sizes which suites me fine. I wear the largest one and it stays nicely put.

The claim to fame of this IEM is that it complies with the Harman target. Let's see if that is the case.

Truthear Crinnacle Zero IEM Measurements
Let's start with our frequency response measurement:
View attachment 230790

I must say I was not prepared for such a tight fit to our target! Other than a hair droop at 20 Hz and a bit deviation here and there, the response hugs our target a wet towel! Very nice. This renders our difference frequency response kind of useless:

Distortion is good enough at lower levels but gets a bit much at maximum SPL:

View attachment 230793

Group delay is not revealing for IEMs and such is the case here:
View attachment 230794

Impedance shows evidence of some tuning in bass frequencies:

The low impedance means many amps and sources can drive it but it is very low. Sensitive is on the low side as well for an IEM:

Truthear Crinnacle Zero IEM Listening Tests
As usual I start with my female vocals. My first reference track had excellent warmth courtesy of proper low frequency response. This continued from track to track with tonality that was just delightful. It not only sounds "right" but also enjoyable. The sound you get is like the best speaker in best room with no room modes. Of course there is no tactile feedback so deep bass doesn't sound the same but you get the picture.

I cranked up the volume on it and it kind of gets loud but I thought the bass started to gradually get distorted. Not a practical problem as you are not going to want to listen at those unsafe volumes.

I am sitting here typing this review and listening to it and marveling how nice every track sounds!

Conclusions
What on earth are you doing reading the rest of this review? Go and buy one of these! I don't care if you don't listen to IEMs normally. You want this IEM so you know what correct tonality is, when you listen with other transducers such as headphones and speakers. Think of it as the tuning fork that a musician uses! This IEM needs to be in your arsenal.

For those of you who use IEMs as I do in summer months (headphones wear too hot), you are in for a treat for peanuts out of your pocket. The science works. Kudos to @crinacle for advocating this execution. We are indebted to you for your contribution here.

I am happy to strongly recommend the Truthear Crinnacle Zero IEM. It brings that incredible harmony of technical excellence and superbly low purchase price.

Two "world records" in two days, not bad...
I already got too many headphones, but at this price, I might soon have one more too many :cool:

/ordered, before the price goes up, already 55 € in Germany

I am with you on this, find it hard to get any Iems to stay firmly put and with a great seal. Other don't have issues. weird thing for me it's only the right ear the problem. absolutely don't have any fit issues with the left. Try many tips and yes tried different tips on left and right. One day maybe I'll find the perfect tip for me but so far it's an issue. I still use Iems but keep refitting, every few minutes and it does get on my nerves and is detrimental to my enjoyment of music in the end.
Ever tried Azla Sednaearfit Xelastec ? They have a certain stickiness and work just fine for me, even with IEMs that were problematic at first. They are a bit expensive but worth the money.

Yes, this earphone can be driven by an iPhone dongle because it has a low output impedance. Not so with every dongle.

OK, purchased on Amazon. Opinions please: do these need a dedicated headphone amp? With low impedance and sensitivity, would the headphone jack on my TEAC AI 301 DA do them justice?

??? I don't think there is a variation with tips. Anyway, i used the medium sized one.

I would try it with whatever you have before spending money on an amp.

Ordered,
It will take 2 weeks with Amazon to Europe so I have to be patient.
