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 THIEAUDIO Monarch MKIV is 3 years newer, but it is 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. For 3 years between them, that is a thin return - treat this as a restyle rather than a new platform.

The 7th Acoustics Supernova is a wired, six-driver balanced-armature IEM tuned for a smooth, natural, and highly musical listen. It excels with cohesive tonality, engaging vocals, and a well-defined stage, though its ultimate resolution falls just short of the very top tier in its price range.
- Pro:Natural, cohesive tuning with excellent timbre
- Pro:Outstanding midrange and vocal reproduction
- Pro:Impressive soundstage and imaging for an all-BA design
- Con:Detail retrieval is not class-leading for the price
- Con:No noise cancellation or wireless functionality
- Con:Availability may be limited for some buyers

- Pro:Reference-grade neutral tuning with excellent clarity
- Pro:Versatile bass boost mode adds flexibility
- Pro:Detailed and extended treble from electrostatic tweeters
- Con:High price point limits accessibility
- Con:Requires a capable source to perform at its best
