Bose QuietComfort 35 II EQ settings for Mac

Last updated: October 2, 2026

Bose QuietComfort 35 II has 4 published AutoEQ corrections, from 3 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 Bose QuietComfort 35 II 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 Bose QuietComfort 35 II, 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 worn pads 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: Bose does not publish a wired or ANC-off mode as a separate product, but the measurement community treats it as one, so this page carries both: the normal active mode and a passive set measured with the electronics out of the picture. They are genuinely different curves, not two readings of the same thing, and which one fits depends on how you actually listen. Each mode rests on two published measurements, so treat either as an informed reading rather than a consensus.

What the Bose QuietComfort 35 II correction changes

These figures come from the measurement by crinacle, the one the picker below opens with. The largest boost is +3.6 dB at treble (8 kHz), and the largest cut is −2.0 dB at upper bass (125 Hz). Total swing across the ten bands is 5.6 dB. Averaged over its bands the treble is lifted by 1.3 dB, more than the other two, which is where most of the audible change lands.

The 4 published measurements on this page, from 3 rigs, do not agree with each other, and the size of the disagreement is worth knowing before picking one. They differ most at upper midrange (2 kHz), where the ten-band figures span 9.1 dB, and least at lower midrange (250 Hz), where they span 2.3 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.

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 Bose QuietComfort 35 II?

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 crinacle's measurement, the ten-band version stays within 7.2 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 Bose QuietComfort 35 II a harder fit for ten bands than most. The largest of those gaps sits around 5.9 kHz, where a cutting filter at 5.94 kHz with a Q of 6.0 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 Bose QuietComfort 35 II 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 Bose QuietComfort 35 II correction on a Mac

To use the Bose QuietComfort 35 II 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 Bose QuietComfort 35 II, 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 Bose QuietComfort 35 II preset above sets the ten-band curve, which is what the free tier applies, so nothing on this page is behind a purchase.

The Bose QuietComfort 35 II is worn around the ear, where the pads decide a good deal of what the measurement rig saw. Worn or replaced pads move the response, which is why several models here carry separate curves for exactly that. If yours are old, expect the correction to be a near miss rather than an exact one.

Most of the measurements behind this page were made with the headphone in its normal listening mode, and active noise cancelling changes the response it is correcting. Switching ANC or transparency on and off is not a small tone change, so a correction that sounds right in one mode may not in another.

Common questions about Bose QuietComfort 35 II 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 Bose QuietComfort 35 II numbers come from?

From 4 published AutoEQ measurements of the Bose QuietComfort 35 II, made by crinacle, Rtings and HypetheSonics. 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 (Passive (ANC off); Standard) are measured separately and corrected separately.

Why is the Bose QuietComfort 35 II preamp negative?

The Bose QuietComfort 35 II correction needs −4.3 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.

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.
