A new wave of Apple Music listeners says the same thing: turn on Sound Check, and everything sounds too low. The complaints started on X, then spilled into a busy Apple Music discussion where people compared notes, swapped fixes, and debated whether Sound Check changes the sound or only the volume.
If you feel that drop right away, you are not imagining the level change. Sound Check’s job is to even out loudness so one track does not blast you while the next one whispers. Apple says Sound Check “adjusts the loudness between different songs to play at the same volume,” and it even calls out a common example: some stereo songs can sound louder than Dolby Atmos songs.
That mission has a side effect. If you listen to loud masters most of the time, Sound Check often turns them down to match everything else. To your ears, that can feel like Apple Music suddenly lost power.
What Sound Check actually does
Think of Sound Check like a steady hand on the volume knob. It aims for consistency across tracks, albums, and playlists, so you do less volume babysitting. That matches what many commenters kept repeating: Sound Check exists to normalize loudness, not to remix your music.
This also explains why people report opposite experiences. If you jump between eras, genres, and masters, Sound Check can reduce the number of “whoa, that one is loud” moments. On the other hand, if you mostly play modern, loud tracks, Sound Check can make your entire session feel quieter than you expect.
Dolby Atmos adds another wrinkle. Atmos mixes often land at a different perceived level, so you can hear bigger swings when you mix Atmos and non-Atmos tracks in the same queue. Apple directly points to this stereo vs Dolby Atmos loudness difference in its own support note about quiet playback.
People swear it sounds “worse” with Sound Check on
A chunk of the debate comes down to a simple listening trap: louder often feels better, even when nothing else has changed. If you turn Sound Check off and a track jumps up in level, your brain can read that as more detail, more punch, more life. Audio engineers have written about this loudness effect for years, and it shows up in everyday listening tests unless you match volume carefully.
That does not mean every complaint is imaginary. Some users describe glitches on desktop where the first seconds play loud and then drop, or playlists that still feel uneven. Those reports are harder to pin down, but they fit a familiar pattern: normalization works well most of the time, then a few tracks behave oddly and ruin your trust.
What you should do if Sound Check feels too low
Start with the settings that change perceived loudness the most, then decide whether Sound Check stays on or goes off.
Fixes you can try now
- Decide what you want more: steady volume or maximum loudness.
If you hate volume jumps, keep Sound Check on. If you want your loud masters to hit hard, turn it off. - If Dolby Atmos tracks sound quieter, test with Atmos off.
Apple calls out that stereo and Dolby Atmos can land at different loudness, so toggling Atmos can make things feel “normal” again. - Turn Sound Check on or off in the right place.
On iPhone or iPad: Settings > Apps > Music > Sound Check. On Mac: Music app > Settings or Preferences > Playback > Sound Check. - Protect your ears if you switch it off.
Use Apple’s Reduce Loud Audio so you can listen louder without spiking past your comfort zone. Go to Settings > Sounds & Haptics > Headphone Safety > Reduce Loud Audio and set a limit you can live with. - If you want a fair comparison, level-match.
When you compare Sound Check on vs off, bring the volume to the same perceived level before you judge “better” or “worse.” Otherwise, the louder option usually wins.
If you listen to playlists, shuffle, and mix formats, Sound Check can save you from constant volume tapping. If you mostly play loud modern masters and you want that extra kick, turning it off will feel better fast, but you should pair it with a headphone safety limit so you do not punish your ears later. Apple’s own guidance makes it clear what Sound Check targets: consistent loudness between songs, especially when stereo and Dolby Atmos tracks collide in the same library.
