I must have duds then because mine have zero bass
You sure you have a good seal?
With the Airpods Pro, its a lot easier to get a good seal and with that, have a good sound quality (especially bass). At least with my ears, so YMMV. The only way for me to get a decent bass sound with the wired EarPods and the regular AirPods is to use little foam pads. Without those, they are way too loose in my ear (they fall out) and sound quality is piss-poor.
I only bought my Airpods Pro a couple of days ago but I like the sound quality A LOT better then my wired EarPods. I must admit though that I have to get used to the in-ear form factor of the Airpods Pro. I have been experimenting with the different tip sizes, right now I am using the largest size. The smallest are too small for me, but when I use the seal test, I always get a good seal with both the medium size and the large size tips... so far the largest tips are the most comfortable for me...
