NiceHCK Rockies lands in the ~$500 bracket with a 1DD+2BA+2EST setup and a surprisingly premium package. The hollow resin shell feels solid, with a metal nozzle, slightly recessed 2-pin, good isolation, and comfy fit. The swappable-termination cable is thick, pliant, and lays flat—no chin slider out of the box, but easy to add—and the excellent case and tip kit push the accessories into “above class” territory.
Tonally, Rockies goes for tight, controlled bass and a natural midrange, capped by upper-treble that’s sparkly yet refined—detailed without getting shouty or brittle. The graph reads largely flat with a tasteful treble lift, translating to a clean, clear presentation that stays engaging rather than fatiguing. It comes across as an “instant classic” tuning: lively, airy, but still grounded.
Compared with brand siblings (DB2 too upper-midsy; F1 Pro/NX8 fine but not special), Rockies feels like the step up. Versus peers, it splits the difference: more air and delicacy than RSV MK2 (which is bassier/darker), less sizzle than sets that chase treble for effect, and broadly similar endgame vibes to “good” units of Mega5-EST—variance there being the rub. Net: a high-value pick at its price, worthy of a Gold Star—not a universal “benchmark,” but a sweet, natural, clear listen that many will prefer, especially with the standout accessories.

You need to be signed in to write your own reviewA lively rendition of the diffuse field tuning that tilts slightly upward for additional clarity. Tastefully bass-boosted DD, clear and clean BA mids with slightly recessed vocals, and standout EST treble presence make an engaging JM-1 all-rounder.
Pros
Lively, unique take on neutral with bass boost. Excellent detail.Cons
An ever so slight increase in bass shelf could provide more dynamicism.Lively tribrid with engaging low end and airy detail that still sounds cohesive. Strong technical performance for the price without losing musicality.
Pros
Punchy, fast bass with good texture and sub-bass reach. Smooth-leaning EST treble with high detail and precise imaging; comfortable fit and solid isolation.Cons
V-shaped balance leaves mids a bit recessed. Treble can lean bright on poor recordings.Find your next IEM:
