Scarlett Mini is framed as a bass experiment first, IEM second: a ~$666 set (or $833 with the light-red “upgraded” cable) that pushes a 30 dB sub-bass shelf so far that every track becomes a bass test. The low end is described as omnipresent—a physical, room-shaking effect that makes even lean recordings throb—while mids/treble behave like a competent $200–$300 set with decent stage and a sweet, crisp top end (not kilobuck texture). It’s also hard to drive, likely due to a heavy crossover network, and scales with power more in weight than in refinement. The upgraded cable gets a thumbs-down on feel and value; the advice is to skip the cable upcharge.

This tuning is called weird but fun—a “bass cannon” for listeners who’ve heard everything and want their library to feel new and outrageous again. The warning is clear: extended use may ruin perception of normal gear because the sub-bass sets a new baseline; take “vacations” from it. For quality-first listeners seeking separation and balance, the rest of the signature won’t justify the price; for bass die-hards, paying a few hundred dollars just for the bass trick might be exactly the point. Measurements won’t look neutral, and that’s by design—this is a specialized, end-of-the-road indulgence rather than a daily driver.

The FATfreq Scarlet Mini is a hybrid IEM positioned in the brand’s “Scarlet” line with a 1DD+2BA configuration and a stated focus on sub-bass power and treble extension; retailer specs list a single dynamic driver plus two balanced armatures, while the brand highlights a “hyper tweeter” system that extends to 40 kHz . Frequency-response measurements published by a retailer show an extreme sub-bass shelf below ~200 Hz with restrained upper-mids and a smooth, airy top end—consistent with a U-shaped, sub-bass-emphasized tuning rather than a neutral target . FATfreq and dealers market the model with the “world’s first 30 dB sub-bass shelf” claim; while that’s a marketing line, the published curves support a very elevated low end in practice .

On technicalities, the Scarlet Mini emphasizes slam and macrodynamics over microdetail: the powerful sub-bass delivers texture and weight, but can modestly mask lower-mid articulation on dense mixes, while treble extension from the dedicated HF driver provides adequate air without aggressive bite . Practical specs—105 dB sensitivity and 16 Ω impedance—suggest it’s easy to drive; the included SPC cable and accessory set are typical for the segment, and the U-shaped, bass-heavy tuning targets listeners prioritizing impact over strict neutrality . Street pricing varies by region and cable option, but the official product page lists an MSRP tier around $799 for the base configuration, which frames expectations on value relative to other mid/upper-mid offerings .
