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 Sivga Lyrebird is 6 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 Sennheiser CX 150BT adds USB-C. For 6 years between them, that is a thin return - treat this as a restyle rather than a new platform.

Sivga Lyrebird
