Why does my music get quieter when I type on iPhone?
Every keyboard click is a short system sound, and iOS briefly turns down whatever else is playing so that sound can be heard — a system-wide habit called audio ducking, not a setting any keyboard controls.
Music or a podcast is playing, you switch over to type a message, and for the length of your reply the audio sits a little quieter than it did a second ago — not paused, not stopped, just turned down, and back to normal the moment you finish. It is easy to assume something is wrong with the keyboard, or with the app playing the audio. Neither is the case. What you are hearing is a normal piece of iOS audio behaviour, and it has nothing to do with which keyboard is on screen.
The mechanism: audio ducking
A keyboard click is a short system sound, the same category of thing as a text tone or the camera shutter — a brief, one-off noise rather than a full audio track. Whenever iOS needs to play a sound like that while something else is already playing, it briefly lowers the volume of that other audio so the short sound can be heard clearly over it, then brings the volume back up once the sound has finished. This is called audio ducking, and it is a system-level behaviour, not something any single app — a keyboard included — decides to do on its own. It is the same reason a notification, a Siri chime or turn-by-turn directions all nudge your music down for a moment rather than talking over it at full volume.
Why this is a different thing from a keyboard sound going quiet
There is a separate, well-known situation where a keyboard click disappears entirely: during a phone call, a voice recording or a screen recording, iOS holds an audio-capture session open and suppresses system sounds like a keyboard click for as long as that session runs. That is the keyboard’s own sound being muted. What is happening with music is the opposite direction — the keyboard’s click is still playing exactly as normal, and it is the other app’s audio that dips for an instant to make room for it. Both involve a keyboard sound and both involve iOS managing audio behind the scenes, but they are unrelated mechanisms pointed in opposite directions.
Why a mechanical keyboard sound makes it more noticeable
Apple’s own single click already ducks whatever is playing, every time, and most people never register it, because the click itself is quiet and easy to miss against music. A keyboard with a distinct mechanical sound — a sharp blue-switch click, a low wooden thock — rides on exactly the same short-sound mechanism and produces exactly the same brief duck, no stronger and no longer. What changes is not the ducking; it is that there is finally something loud and distinctive enough on the keyboard’s side to make the dip in the music worth noticing. Typing a long message quickly can make it sound like the music is very faintly pumping in time with your keystrokes — that impression is real, and it is just this same short duck happening once per key, back to back.
Turning it off
There is no separate switch for “keep the keyboard sound but stop the ducking,” because the duck is not a keyboard setting at all — it happens automatically anywhere a short system sound and other audio overlap. The only way to remove it is to remove the sound that triggers it: turn off key sound entirely, in Settings → Sounds & Haptics → Keyboard Feedback for Apple’s own click, or inside a third-party keyboard’s own settings for its sounds. With no click playing, there is nothing for iOS to duck the music for. Haptic feedback is unrelated either way, since it comes from the Taptic Engine rather than from anything audio-based.
Where Kibo fits
Kibo’s key sounds play through that same short system-sound mechanism as Apple’s own click, so they duck background audio in exactly the same brief, ordinary way and need no special permission to do it — Full Access, which Kibo leaves off by default, has nothing to do with sound at all. It is free to download.
Frequently asked questions
Does this only happen with third-party keyboard sounds, or with Apple’s own click too?
Both. Every keyboard click, Apple’s or a third party’s, plays through the same short system-sound mechanism, so the same brief duck to other audio happens either way. A distinctive mechanical sound does not duck harder — it is just more audible against the dip.
Is this the same thing as my keyboard sound going silent during a call?
No, the direction is reversed. During a call or a recording, iOS suppresses the keyboard’s own click entirely. What happens with music is the opposite: the click still plays as normal, and the music briefly dips to make room for it.
Can I keep the key sound but stop the music from dipping?
No — there is no setting for that, because the dip is not something the keyboard turns on. Turning off key sound is the only way to remove it, since it removes the short sound that triggers the duck in the first place.
