Letshuoer Cadenza 4
A mid-first hybrid that reviewers call natural and underrated — and that splits them almost down the middle on whether it's smooth or bright, and whether its lean bass is enough.

Letshuoer is a Chinese in-ear monitor maker founded in 2016 (originally as Shuoer Acoustics) and based in Dongguan, known for its planar-magnetic and hybrid IEMs.

A mid-first hybrid that reviewers call natural and underrated — and that splits them almost down the middle on whether it's smooth or bright, and whether its lean bass is enough.

The planar that turned the treble down: a warm, bass-first $99 set that most reviewers love — and that a growing file of owners has watched go quiet in one ear.

The planar-war bargain that still divides a room: class-above detail and bass for $135, and a treble half the room calls crisp and half calls sibilant.

The S12 with the treble filed down: the smoothest, most comfortable, best-boxed version of a budget-planar legend — and the one that finally splits its fans on whether it lost the plot.

A kilobuck IEM that spends its whole budget on the midrange — and asks you to give up the bass.

One planar, two opposite verdicts — and a treble peak that moves an octave with how deep it sits.

The planar that stopped trying to sound like a planar — and split the room over whether anything was gained.
