IEM· $20· 2026-08-017Hz 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· 2026-07-227Hz 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.

IEM· $229· 2026-07-097Hz Timeless II
The planar that started the craze, retuned four years on — still a benchmark for detail and build, still arguing about its treble, bass and fit.

- IEM· $20
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.

7Hz x Crinacle Divine
The planar that finally tames the peak — a smooth, vocal-forward $149 set whose only real arguments are how much bass it has and whether the big shell fits.

7Hz Timeless
The planar that lit the budget-IEM fuse — loved for its detail and deep bass, argued over for its bright, peaky treble.
