Video reviews we found, each condensed to its verdict. They do feed the HearWiki score, at a measured weight below what a published written review carries.
Reviewers largely agree that the Subtonic STORM is a top-tier, reference-grade IEM with exceptional technical detail, natural timbre, and well-controlled bass, though its $5,200 price tag is a major hurdle.
20:12The reviewer finds the Subtonic Storm to be an exceptional, near-reference IEM with a mostly balanced tuning and tasteful treble coloration, though its high price and anatomy-dependent treble response make it a niche product. The build, comfort, and accessories are praised, but the treble quirks and power requirements are noted as potential drawbacks.
18:31The reviewer is highly impressed with the Subtonic STORM, calling it an exceptional and versatile earphone that excels across all genres, with standout bass, mids, and treble. It is nearly his favorite set, only losing to the Grand Maestro due to the latter's multiple tuning profiles, despite the STORM costing twice as much. He praises its technical performance, especially in resolution and tonality, and disagrees with others who found the soundstage lacking.
28:06The reviewer and his guests compare the Subtonic Storm against several high-end IEMs and the LCD-X headphone, concluding that the Storm is the most natural and detailed of the bunch, with an effortless, reference-like tuning. They praise its timbre and micro-detail retrieval, though they note it can initially come across as boring before revealing its quality. Overall, they consider it the best-sounding IEM in the comparison, but acknowledge its very high price.
4:28The reviewer strongly criticizes the Subtonic STORM, calling it a scam due to its exorbitant price, misleading marketing claims about flatness and phase response, and a jagged frequency response graph that they obtained from the company. They argue that cheaper IEMs outperform it in smoothness and sound quality, and that the bundled cable is grossly overpriced for its specifications.
19:21The reviewer compares the Subtonic STORM and Mysticraft Hex, concluding both are top-tier IEMs with different philosophies. The STORM offers a more neutral, reference-oriented sound with superior note decay and technical detail, while the Hex is more flamboyant and upfront with its detail presentation. The reviewer ultimately suggests the STORM is the more refined and natural-sounding of the two, though both are excellent.
