HIDIZS - Viento A (UIEM)

Just a prototype tuning. IMO, the best tuned IEM was the Viento A, but it had too much upper treble. I honestly don't think IEMs need that much bass. No matter how well you control it, within an IEM format, modern big bass (+8dB at 20Hz) always ends up bleeding. Prototype tuning gives just as nice thump and punch texture without mid-bass bleeding.

Incredibly based take. Dr. Olive has an unpublished study where the 2nd largest group of respondents on average preferred a much lesser bass shelf than was seen in his original 2016 paper (like, in the neighborhood of 2-4 dB bass shelf and very little treble reduction instead of 6-10 dB bass shelf and 3-4 dB treble reduction), and I think this group of listeners who like less bass are currently an underrepresented market. That said, because IEM midranges are typically quite forward around 1-2 kHz, there is an argument that larger bass shelves are needed to offset the shoutiness that often comes with this. With the Viento this isn't as much of a problem because the structure of its upper midrange is quite "DF-like," but with other IEMs I think I would probably need more bass/low mids to offset the commonly occurring 1-2 kHz bump.
