7hz x Crinacle Diablo - Reviews & Ratings

The 7hz x Crinacle Diablo is a single-driver planar IEM built around a third-generation 14.5 mm planar magnetic transducer in a CNC-milled aluminum shell with a detachable 2-pin cable . Positioned at an MSRP of $149, it targets the upper-budget segment rather than competing with mid-tier hybrids; Linsoul’s sales materials explicitly list the Diablo at $149 during the 11.11 early-bird program . The hardware package is straightforward rather than luxurious, but the metal construction helps with durability and fit consistency .

Tonally, the Diablo follows a neutral-with-bass-boost approach anchored by an advertised ~12 dB low-frequency shelf, which prioritizes sub-bass weight over mid-bass bloat . Frequency-response plots hosted on Crinacle’s graph tool show a pronounced bass elevation with controlled upper-mid energy and a generally restrained treble, landing the set on the warmer, fuller side of “Harman-adjacent” without aggressive peaks . This tuning gives kick drums and electronic sub-bass clear authority while keeping vocals reasonably intact, though some midrange clarity can sound slightly recessed compared with leaner references .

Technical performance is competent for a budget planar: transients are clean and fast, detail retrieval is above average for the price, and imaging is orderly, though stage size remains modest and macrodynamics are more smooth than explosive. Considering the $149 bracket and the bass-emphasized target, the Diablo reads as a value-oriented specialist for listeners prioritizing sub-bass grip over midrange forwardness . Build quality and the straightforward accessory set are in line with expectations for this tier, and the 2-pin interface ensures easy cable swapping if needed .
