Sound difference between 2 pairs of AirPods 3?

[grator]

Hi,

I currently have 2 brand new pairs of Airpods 3, and I noticed that both pairs don't sound the same.
One has a lot of bass, as the other one...has barely more than a pair of AP2.

Both pairs were BNIB and are definitely genuine. I couldn't find anything like this on internet, but I often read some found AP3 has a lot of bass (and even too much for some), as for others, they sound tiny.

Did anyone already experienced this?

Thanks.

Make sure the settings for both pair of AirPods are the same. Especially the eq setting. Find it difficult to believe it’s a hardware issue.

Obviously, everything is the same. No custom settings, no accommodation settings, tried to reset them multiple times.
The configuration is exactly the same: no EQ, no custom, no spatial audio.
