Beats Solo 4 EQ settings for Mac

Last updated: September 15, 2026

Beats Solo 4 has one published AutoEQ correction, measured by Rtings, and it is on this page in full. Below is the curve, the exact parametric filters behind it, and a one-click preset for EQBase. 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.

Worth knowing: Rtings is the only rig to have published a Solo 4 measurement so far, and what it shows is a change of direction. Every Solo3 reading asks for 2 to 5 dB to come out of the midbass; this one asks for a little to go in, and spends its largest move, 4.5 dB of cut, at 4 kHz instead. If you are coming from an older Solo, do not assume the curve you were using transfers.

Each measurement below carries four things: the 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 fit of that correction. The ten-band figures are what the downloadable preset applies, so what you hear matches what is written here. 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.

The correction, measurement by measurement

Preamp: -2.7 dB
Filter 1: ON LSC Fc 105 Hz Gain 1.4 dB Q 0.70
Filter 2: ON PK Fc 920 Hz Gain 3.4 dB Q 0.19
Filter 3: ON PK Fc 3842 Hz Gain -5.2 dB Q 1.98
Filter 4: ON PK Fc 1054 Hz Gain -4.7 dB Q 0.97
Filter 5: ON PK Fc 7703 Hz Gain -2.0 dB Q 0.67
Filter 6: ON HSC Fc 10000 Hz Gain 2.7 dB Q 0.70
Filter 7: ON PK Fc 75 Hz Gain -1.4 dB Q 2.28
Filter 8: ON PK Fc 9444 Hz Gain -1.1 dB Q 2.03
Filter 9: ON PK Fc 137 Hz Gain 0.7 dB Q 2.00
Filter 10: ON PK Fc 51 Hz Gain 1.3 dB Q 4.12

What this correction changes

The largest boost is +1.8 dB at midrange (500 Hz), and the largest cut is −4.5 dB at presence (4 kHz). Total swing across the ten bands is 6.3 dB. Averaged over its bands the treble is pulled back by 1.3 dB, more than the other two, which is where most of the audible change lands.

With a single published measurement there is nothing to cross-check the figures against, so treat them as a good starting point rather than a settled answer, and trust your own ears over the last decibel.

Applying this on a Mac

The Beats Solo 4 sits on the ear rather than around it, so how hard the pads press and where they land shift the response by more than most corrections do. Small adjustments to the headband are worth trying before concluding the curve is off.

The Beats Solo 4 connects over Bluetooth, so the Mac's own headphone amplifier never enters the picture: macOS encodes the audio and the headphone's electronics drive it from there. Nothing about amplification applies here, but the preamp does. Leave the headroom the preset asks for, because a boosted band that clips does so before the signal ever leaves the Mac.

In EQBase the fastest route skips this page entirely: open the Headphones pane, search for your model, and apply the correction. The Beats Solo 4 is in the built-in catalog along with 8,665 other models. The preset above exists for people who want to see the numbers first, or who want a specific measurement rather than the default one.

Either way the correction applies to every app at once, and the free tier carries it with no time limit. The Beats Solo 4 preset above sets the ten-band curve, which is what the free tier applies, so nothing on this page is behind a purchase.

Common questions

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 Beats Solo 4 numbers come from?

From one published AutoEQ measurement of the Beats Solo 4, made by Rtings. AutoEQ computes the correction by comparing that measured frequency response against a target curve, so the filters below are only as good as that single measurement: with nothing to cross-check it against, treat it as one informed opinion rather than a consensus.

Why is the Beats Solo 4 preamp negative?

The Beats Solo 4 correction needs −2.7 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.
