Band: opinion spread · Dot: weighted average
The most-argued axis. The top end is detailed and extended, and for a large group it's smooth, refined and non-fatiguing. But an equally large contingent — including treble-sensitive listeners — hears it as spicy, metallic (a BA timbre on cymbals) or occasionally sibilant, and measurement-aware reviewers flag select tracks being 'over-sharpened.' The split tracks treble sensitivity, volume, tips (wide-bore brightens, narrow/foam tames) and source; several who were put off at first say their ears adapted.
Measured
Measurement-aware reviewers read the FR as a dip around 5 kHz into a ~6 kHz valley — which pulls 'heat' out and lets 'air' breathe — before upper-treble lifts near 8, 10 and 15 kHz. That upper energy plus the balanced-armature tweeters is what some hear as air and detail and others as a metallic, over-sharpened edge; wide-bore tips push it brighter, narrow/foam tips tame it.
vs. listeners — The same extended top end reads as 'smooth, refined, non-fatiguing' to many reviewers and as 'metallic / over-sharpened / sibilant' to treble-sensitive listeners. The upper-treble lifts are physically there; because tips, source and volume move them so much, there isn't one 'true' treble here.
“A near-effortless sense of extension and refinement defines the treble of the XENNS Mangird Top Pro.”
