AirPods 4 — Distortion/Crackling on Bass

Hello

I recently purchased a pair of AirPods 4 ANC, and immediately noticed distortion and crackling sounds on bass frequencies in certain songs.

To make sure it wasn’t just my unit, I went back to the store where I bought them. We tested three more brand-new pairs (one was unpacked right in front of me), and all of them produced the exact same distortion at the exact same spots in music tracks.

The issue happens:

with both Noise Cancellation on and off, at medium to high volume levels,

and is especially noticeable between 40–120 Hz (bass frequencies).

This seems to be a widespread problem, not an isolated defect. Replacement doesn’t help because every unit has the same issue.

I’d like to ask:

Is Apple aware of this issue with AirPods 4?

Will there be a firmware update or a replacement program, similar to what happened with AirPods Pro (1st gen crackling issue)?

Please confirm that this has been reported to engineering.

Thank you.

At this point I would make an appointment and take the AirPods into the nearest Apple Genius Bar or Apple Authorized Service Provider for a free diagnostic test.


NOTE: the diagnosis is free at an Apple Genius Bar but you will probably be charged for the diagnosis at an Authorized Service Provider with the diagnostic fee waived if you have them do the repairs. If you're still under warranty or AppleCare repairs will be free.

Yep, same. I have it too on my airpods 4 anc. I think if apple see it, they fix it in next firmware update.

But, I don't have such a problem when music works through applications, such as spotify. Basically, this manifests itself when I listen to shooting (mostly human speech) through low-quality equipment, etc., then the crackle goes, even with the functions turned off, which suggests that cleaning the net will not help.
