Budget planar & dynamic IEMs

7Hz (also styled 7Hertz) is a Chinese in-ear monitor brand known for value-oriented sets that bring planar-magnetic and other higher-end driver types to low prices; its budget models are sometimes sold under the Salnotes label, and it reaches most markets through distributors rather than a first-party store.

7Hz Timeless II

The planar that started the craze, retuned four years on — agreed on its detail and build, still arguing about its treble, its bass, its fit and whether it's still the one to buy.

7Hz x Crinacle Divine

The planar that finally behaves — smooth, vocal-first and easy to drive, with the arguments saved for its bass, its big metal shell and whether it lasts.

7Hz x Crinacle Salnotes Dioko

The $99 planar everyone measured, half of them loved, and a loud minority regret.

7Hz x Crinacle Diablo

Nineteen graphs agree on the shelf to within a decibel. Fourteen ranking critics still score it anywhere from 2 to 8.5.

7Hz Legato

Fourteen rigs agree on the bass. The reviewers do not agree on whether it is a feature.

7Hz Sonus

Everyone agrees the vocals sit forward. Nobody agrees about the top end.

IEM$20

7Hz Salnotes Zero

The $20 set that made cheap IEMs serious — and that measurement forums and ranking lists still score at opposite ends of the scale.

IEM$30

7Hz Elua Ultra

A ~$30 dual-dynamic set that leads with deep sub-bass and a big stage — the one real argument is whether its lively top end reads as airy and smooth or grainy and bright.

7Hz x Crinacle Zero:2

The $25 sequel that swapped the original Zero's sparkle for slam — a near-consensus budget champ whose one real argument is whether the smoother treble is a comfort win or a step too dark.
