Youtube Video Summary
Hidition is framed as an OG IEM house (founded 2003), and the Viento is praised as the rare decade-old set that still sits in the top tier. Released in the height of the driver wars, it rejected driver-count inflation for a 4-driver, 4-way crossover architecture—each BA handling its own band: sub-bass, lower mids, upper mids, treble. The result is “efficiency” engineering that prioritizes clean division of labor over headcount, following the neutral lineage of the NT6 while modernizing with a subtle sub-bass lift.
The Viento’s two-switch system is highlighted as unusually precise: one switch for sub-bass, one for lower mids, yielding four distinct tunings—A (neutral), B (sub-bass boost), C (lower-mid warmth), and D (both). It’s noted that the custom shell outperforms the universal demo (which can sound a bit bright/shouty due to fit depth), making this one of the few customs actively recommended. In 2023 it sits at S- on the ranking list: versatile across configs, close to an IEF-neutral target, and—relative to today’s market—“cheap” at about $1,000 from Zeppelin & Co. Overall, the Viento is portrayed as lightning in a bottle: enduring tuning, elegant engineering, and real-world usability that keeps it in regular rotation years after release.

Youtube Video Summary
Hidition Viento B aims for a reference-lean balance: a leveled sub-bass shelf to around 200 Hz, a lean lower midrange, and very emphasized upper-mids with a notable mid-treble lift. On paper it graphs cleanly, but in practice the contrast thins out note weight and exposes a ringy decay on upper harmonics, pushing cymbals and sibilants forward more than natural.
Technicalities are mixed. Microdynamic contrast is the standout, with low-level inflections popping more readily than peers, yet imaging and stage size hover around average for the price. BA timbre remains audible, and the elongated nozzle that mimics a CIEM fit can be uncomfortable unless a deep insertion is possible; the CIEM version is said to mitigate several of these concerns.
