Check out the frequency response curves yourself of the airpod pros [0] and say, an open-back sennheiser hd650 pair [1]. The airpods have a huge bump at about 1.5kHz to 3.5kHz (mids), while the sennheisers are more neutral in low frequencies but also have a bump at ~3kHz to ~7kHz.

Nothing will beat open-back headphones on a good system, but apple's stuff as of late is plenty good.
