The
Letshuoer Cadenza 4 is a 3 BA + 1 DD hybrid, comprised of 2 Knowles BA and 1 Sonion BA, plus a 10 mm beryllium DD.
It has Letshuoer's classic Fisher Price resinish finish that is very comfortable and light.
Comes well accessorized with a modular cable, hard round case and an array of eartips.
This IEM will be eargasmic to measurebators on graphs, but on actual listening, it is also really superb tonally. Instead of the usual Harman sidegrade spam we see each week, the Cadenza 4 sports a warm neutral sub-bass boosted tonality, which is very smooth and pleasant.
Bass is tight and fast, with good texturing, focused at the sub-bass (ie no mid-bass bleed). The midrange is not depressed with good transparency and euphonia. This IEM is suitable for sibilant-fearing or pinna gain-sensitive folk.
Soundstage is above average with good imaging and layering. It isn't the most micro-detailed focused in view of not being overly steroid boosted in the treble, but resolution is still very presentable for a warmish tonality. Note edges are a tinge blunted to not cause fatigue.
I think this IEM is tuned refreshingly (in a good way) compared to the hackneyed sidegrade Harman fare. Perhaps only trebleheads will need to look elsewhere, but it's very promising from out-of-the-box impressions.
Will do some more testing and report back with A/B comparisons against other hybrids.
