Truthear x Crinacle Zero RED has 22 published AutoEQ corrections, from 14 measurement rigs across 2 variants of the model, and this page carries every one of them. macOS has no system-wide equalizer of its own, so applying a correction to everything your Mac plays, rather than inside a single player, needs an app that sits on the system audio path.
Who it is for: anyone listening to the Truthear x Crinacle Zero RED on a Mac who wants its measured tonal balance pulled toward a neutral target.
What a correction is: a set of equalizer filters that the open-source AutoEQ project computes by comparing a published measurement of the headphone with a target curve.
What this page holds: for every measurement, the curve, its parametric filters, the same filters as copy-paste text, a ten-band version and a one-click EQBase preset.
Which variant is yours: the 2 variants in the measurement picker are different versions of the Truthear x Crinacle Zero RED, so pick the one that describes your own pair before choosing a measurement of it. Standard means the measurement was published without a revision or condition noted.
What it cannot do: it changes frequency response only. It will not make up for a tip that does not seal or for distortion, and it was measured on someone else's pair, not yours.
What you need: any parametric equalizer takes the filters, on any platform. The preset needs EQBase, free on macOS 14.4 or later.
Worth knowing: This is the most-measured model on the site, fourteen published curves for the standard nozzle and eight more for the bass nozzle, and it also needs the least correction of anything here: under 1 dB on average across the ten bands. That is largely what buying a Crinacle-tuned IEM gets you. Pick the curve matching the nozzle actually fitted, because the two are voiced differently on purpose.
What the Truthear x Crinacle Zero RED correction changes
These figures come from the measurement by oratory1990, the one the picker below opens with. The largest boost is +1.6 dB at treble (8 kHz), and the largest cut is −1.7 dB at top octave (16 kHz). Total swing across the ten bands is 3.3 dB. Across the three thirds of the band the average movement stays under a decibel, so this is a fine-detail correction rather than a tonal rebalance.
The 22 published measurements on this page, from 14 rigs, do not agree with each other, and the size of the disagreement is worth knowing before picking one. They differ most at top octave (16 kHz), where the ten-band figures span 7.5 dB, and least at midrange (1 kHz), where they span 1.9 dB. A spread that wide usually means the rigs disagree about the seal or the coupler rather than about the headphone, so prefer the measurement whose conditions match how you actually wear them.
The Truthear x Crinacle Zero RED corrections, measurement by measurement
Pick a measurement to see its correction curve, its parametric filters, the same filters as copy-paste text in AutoEQ's format (which Equalizer APO and Peace, REW and most desktop parametric equalizers import, and which EQBase's own Expert EQ reads and writes), and EQBase's ten-band version, which is what the downloadable preset applies.

Ten-band or parametric EQ for the Truthear x Crinacle Zero RED?
A parametric equalizer lets every filter take any frequency, gain and width, where width is written as Q and a higher Q means a narrower filter, so it can reproduce AutoEQ's filters exactly. A ten-band graphic equalizer has ten fixed bands an octave apart, from 31 Hz to 16 kHz, all the same width, so it can only approximate them. EQBase's ten-band version sets those ten gains to match the parametric curve at the band centers, allowing for how the bands overlap, rather than reading the curve off at each center.
On oratory1990's measurement, the ten-band version stays within 1.4 dB of the parametric curve between 40 Hz and 10 kHz. Across all 8,666 corrections in EQBase's catalog the median for that range is 3.3 dB, which makes the Truthear x Crinacle Zero RED an easier fit for ten bands than most. The largest of those gaps sits around 5.9 kHz, where a boosting filter at 6.16 kHz with a Q of 2.4 is far narrower than a one-octave band can follow.
Use the parametric filters if your equalizer accepts them: they are the correction exactly as published. The ten-band version is for equalizers with fixed sliders, EQBase's free tier among them, and it is what the downloadable preset applies. On EQBase Pro, applying the Truthear x Crinacle Zero RED from the Headphones pane uses the parametric filters directly, and the preset carries them as well, one switch to Expert EQ away. AutoEQ publishes its own ten-band file on the same grid, fitted to the raw measurement rather than to these filters, so the two agree closely through the midrange and can differ at the extremes.
How to use the Truthear x Crinacle Zero RED correction on a Mac
To use the Truthear x Crinacle Zero RED correction on a Mac, apply it with an equalizer that runs on system audio, so it reaches every app at once. In EQBase the fastest route skips this page: open the Headphones pane, search for the Truthear x Crinacle Zero RED, which is in the built-in catalog of 6,033 models, and click the measurement you want. The preset above does the same from a file, for anyone who wants to see the numbers first or a specific measurement rather than the default one.
Either way the free tier carries it with no time limit. The Truthear x Crinacle Zero RED preset above sets the ten-band curve, which is what the free tier applies, so nothing on this page is behind a purchase.
The Truthear x Crinacle Zero RED is an in-ear monitor, and its bass depends far more on the seal than on anything in this correction. A tip that does not seal loses the low bass outright, and no amount of boost puts it back. If the bottom end still sounds missing after applying this, change tips and re-seat them before deciding the curve is wrong.
Something this small is sensitive enough that a Mac's own output drives it without help, so the correction is doing all of the work here rather than sharing it with an amplifier.
Common questions about Truthear x Crinacle Zero RED EQ
Do these EQ settings work on any Mac app?
Yes, if the equalizer runs on system audio rather than inside one player. EQBase processes everything the Mac plays, so the same correction applies to Spotify, Safari, YouTube, games and calls. The Music app's own equalizer only affects Music.
Where do the Truthear x Crinacle Zero RED numbers come from?
From 22 published AutoEQ measurements of the Truthear x Crinacle Zero RED, made by oratory1990, crinacle, Rtings, Super Review, Harpo, Filk, Fahryst, Jaytiss, Kazi, ToneDeafMonk, DHRME, Auriculares Argentina, freeryder05 and Bakkwatan. Each one is a real frequency-response measurement compared against a target curve, and each produces its own set of filters. They are all on this page rather than averaged together, because a measurement belongs to the person who made it. The 2 variants (Bass+ nozzle; Standard) are measured separately and corrected separately.
Why is the Truthear x Crinacle Zero RED preamp negative?
The Truthear x Crinacle Zero RED correction needs −2.1 dB of headroom on its default measurement, so the preset pulls the signal down by that much before the boosts are applied. Boosting a signal that is already near full scale would clip it, and the negative preamp is what buys the room. Skip it and loud passages distort. That is a small figure, meaning this correction is mostly cuts rather than boosts, so it costs very little loudness.
Can I use these filters in a different equalizer?
Yes. The filter table is a standard parametric list: type, frequency, gain and Q. Any parametric equalizer that accepts those four values per band will take them, on any platform. The one-click preset is only a shortcut for EQBase users.
