7Hz x Crinacle Diablo

Sources split on the same shelf. The large majority — most written and video reviewers and nearly every owner — hear deep, textured, physical bass that the planar driver keeps fast enough to stay clean, and several stress that it is thick, mid-bass-led weight rather than sub-bass-only rumble. A smaller, heavier-weighted camp led by the two 2/5 critics hears the same shelf as soupy bloom that dominates the mix. A few owners say the opposite again: that it is not bassy enough to earn the name.

Sources split almost evenly. One camp hears a warm, full, natural midrange — vocals with body and crisp transients that never turn shouty, several calling it the quiet strength of the set. The other hears the same region recessed by design behind the shelf, with vocals that turn husky, veiled or 'cooked', female voices paying more than male. Both camps agree there is no planar metallic edge and no sibilance.

Mostly agreed: smooth, safe and non-fatiguing, with enough extension that the set does not read as closed-in, and none of the older 7Hz planar zing or sibilance. A minority hears the same top as dark, short of sparkle and air, and names it the reason detail goes missing.

“Treble here is smooth, and I mean that as description and not as a compliment or an insult.”

Mahir Efe Falay, Mobileaudiophile

“Due to its relaxed highs, the Diablo is good for treble-sensitive listeners but it creates a darker presentation.”

David Becker, Prime Audio

“Some may even find the treble dark.”

Sources split three to one. Most call it a warm, thick, fun V-shape done with unusual coherence — a genre specialist for hip-hop, EDM, metal and live recordings rather than an all-rounder, and several say it never sounds unbalanced despite the numbers. The critics call it simply too warm and too bassy to be balanced at all and point buyers at the Divine.

Sources split. The larger camp finds the stage wide, layered and unusually immersive for a planar at the price — several Head-Fi listeners call it the biggest they have heard under $200. The smaller camp hears the bass fill the head and pull the presentation inward, describing it as intimate, contained or compressed on busy tracks.

Mostly praised: placement is tidy and separation holds up better than a shelf this size suggests, and the gaming reviewers rate it usable if not competitive-grade. The dissenters hear the bass mask separation and blur layering once a mix gets dense.

“Despite that, the imaging is quite pinpoint, making it easy to determine the position of elements within the stage.”

David Becker, Prime Audio

“The imaging and layering were also a bit skewed due to the bass instruments being really up front.”

Sources split down the middle, and this is where the two-star reviews come from. One camp hears real planar micro-detail — percussion articulation, layered crowds, guitar grain — surviving under the shelf. The other, including the only written review to score it below four, finds resolution below average for $150 with micro-details simply absent, and calls any extra low-frequency texture an illusion of the boost rather than resolution.

Near-unanimous: this is the set's core strength. Reviewers on both sides of the bass argument describe slam, physical impact and a fast attack that a dynamic driver at the price does not match, and note it scales louder without strain. The lone dissent finds the planar bass not fast or dynamic enough to justify the quantity.

“There’s real slam here, the kind of low-end you feel.”

Tom Wolverson, Aussie Audiophile

“a pressure event rather than a note”

Mahir Efe Falay, Mobileaudiophile

Mostly praised: an 8 g shell smaller than the Timeless or Dioko, comfortable for long sessions, with several small-eared listeners singling it out. The minority complaints are about stability rather than pressure — a rounded shell that sits on the tip seal alone and can 'joystick', a heavy stock cable that drags it, and one listener who needed foam to seal.

“Comfort is genuinely good because of the size.”

Mahir Efe Falay, Mobileaudiophile

“As for comfort It did not fit well in my ear due to the weight and shape.”

PrinceLestat, Head-Fi

Sources split, and almost entirely over the cable. The shell (CNC aluminium, matte, fingerprint-proof) and the oversized zip case draw praise from nearly everyone. The stiff, heavy, memory-prone single-crystal-copper cable with a fixed 3.5 mm plug is the most repeated complaint on the record, and a few owners report the 2-pin socket gripping it so hard that removal damaged a connector. A minority like the cable as it is.

Agreed and unremarkable: the small vented metal shell isolates respectably once sealed — enough for planes and streets, not vacuum-tight.

“I found them very comfortable, and they provide a respectable level of passive noise isolation.”

David Becker, Prime Audio

“The sound isolation in the Devils is simply good, but not like a vacuum.”

IceIceberg, Head-Fi

Sources split. The majority call it the bass-planar many were waiting for and an easy recommendation at $150, several owners preferring it to sets costing far more. The minority — the two 2/5 critics, Prime Audio, Jays Audio and a few owners — say it does not stand out in a savage $100–200 planar field, that the Divine or a cheaper set is the safer buy, and that it only makes sense on sale.
