Hi-end wired in-ears / headphone won't go away anytime soon thank god. Having firefly dac and sennheiser ie-900 in addition to AirPods would give you access to Apple Music hi-res lossless on the go. The only problem is - after having used AirPodsPro 2 my tolerance for street noise is extremely low and noise cancellation kind of competes with reference sound reproduction features in a lot of products I think.
