My AirPods sound perfectly normal when I first open the case, but after a short time the left earbud starts making a buzzing or rattling noise, especially during songs with heavy bass. I've cleaned both earbuds, forgotten and re-paired them, and tried troubleshooting for about an hour, but the issue keeps coming back. They're genuine AirPods purchased from an authorized Apple seller, and I've only had them for around three weeks. What else can I try, or should I have them replaced?

The fact that it now starts buzzing almost immediately makes it less likely to be a temporary obstruction. Avoid putting anything else into the speaker grille, since moisture or pressure can make things worse. With a recent purchase and active coverage, a warranty replacement is the most practical solution.
You can try resetting the AirPods and checking that the firmware is up to date, but a brand-new pair shouldn’t develop a persistent buzz after only a few weeks. If the sound remains after a reset and it happens across different devices or audio sources, contact Apple support or the authorized seller. They should be able to run a diagnostic and replace the faulty earbud.
