Generation & platform
The scores rank quality. This is the other question: is the newer one actually newer technology, or the same platform in a new shell?
Same generation
The Wavefun Wave Pro X is 8 years newer, but it is the same generation of hardware: nothing in the radio, the codecs or the noise cancelling separates them. The platform is level; the newer hardware shows up in convenience features instead - the Wavefun Wave Pro X adds USB-C. For 8 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said
AKG K 550
The AKG K 550 is a wired, closed-back over-ear headphone that delivers a notably wide and detailed soundstage for its type, with clear vocals and solid low-end punch. Its sturdy build and plush fit make it comfortable for long home listening sessions, though its performance can be sensitive to how well it seals around the ears. Overall, it offers strong audio fidelity for the price, but some listeners may find its treble character and fit-dependent bass a bit inconsistent.
