KZ Sonata: a wired balanced armature IEM with 28 BA drivers per side, in the version with fixed, non-adjustable tuning. It's aimed at listeners stepping up from single dynamic-driver IEMs who want to hear what a large armature array does for layering and separation, and who'd rather set one voicing and forget it.
Who the KZ Sonata is for
Upgraders from single dynamic-driver IEMs: With 28 armatures per side, it shows what a large BA count does for layering and separation.
Set-and-forget listeners: One fixed voicing means no switchable settings to second-guess.
Anyone with a dongle DAC or DAP: It's a wired set that plugs straight into the source you already own.
Skip it if: you want to change the voicing later; this version's tuning is fixed.
