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 KZ PRX is 6 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 6 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said
FiiO F5
The FiiO F5 is a semi-open in-ear monitor built around a single 13.6mm dynamic driver, delivering a smooth and balanced sound with a notably wide soundstage. Its detachable MMCX cables, including a balanced option in the box, add versatility for wired listeners, though it doesn't chase the ultimate detail retrieval of pricier models. This is a solid, affordable choice for those prioritizing an airy, natural presentation over analytical precision.
- Pro:Wide, open soundstage for a dynamic driver
- Pro:Detachable MMCX cables with a balanced cable included
- Pro:Smooth, non-fatiguing tonal balance
- Con:Lacks ultimate detail and clarity compared to higher-end IEMs
- Con:No active noise cancellation or app support
- Con:Semi-open design may leak sound and let in ambient noise
KZ PRX
The KZ PRX is a budget-friendly planar magnetic IEM that offers a balanced, warm-leaning sound with strong detail retrieval and capable imaging for its price. It excels in sub-bass presence and smooth mids, though it demands proper amplification and ear tips to perform at its best. Its soundstage is decent but not exceptionally wide, and the stock cable is a noted weak point.
- Pro:Excellent value for a planar IEM
- Pro:Balanced, warm sound with good detail
- Pro:Strong imaging and separation for the price
- Con:Requires a capable source and good ear tips
- Con:Stock cable limits performance
- Con:Soundstage is only medium-sized
