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
Both shipped in 2025. These are the same generation of hardware - nothing in the radio, the codecs or the noise cancelling separates them. Nothing separates them on convenience features either, so the choice comes down to tuning and price.

Overall, it is a solid specialized pick for bass enthusiasts rather than a versatile all-rounder.

- Pro:Good clarity and separation for a bass-heavy set
- Pro:Easy to drive with most sources
