Band: opinion spread · Dot: weighted average
Sources split, roughly two to one. The majority — most of the mainstream press and most Amazon owners — hear a lively, bass-and-treble-forward tuning that is fine or better for everyday listening, especially after the app's hearing test. The minority is the group that measures and compares: they hear a tuning so lopsided that vocals sound boomy and thin at once, and say the eight-band EQ can soften it but not fix it.
Measured
Two rigs, each compared with the Harman over-ear target, agree to within about 2 dB below 6 kHz. On oratory1990's GRAS rig the bass sits 4.3–4.9 dB above the target from 20 to 100 Hz, the 300–700 Hz region sits up to 3.9 dB below it, 1.5 kHz is 4.0 dB above, 3 kHz is 2.9 dB below, and the treble rises to +5.3 dB at 7 kHz, +7.1 dB at 8 kHz and +12.8 dB at 9 kHz. RTINGS' rig reads +2.7 to +4.2 dB in the bass, the same trough, +2.9 dB at 1.5 kHz and +13.8 dB at 9 kHz. RTINGS' verdict calls the profile “V-shaped”; SoundGuys' own measurement shows “a U-shaped frequency response that amplifies low and high frequencies while attenuating mid-frequencies.”
vs. listeners — Nobody disputes the shape; the argument is whether it matters and whether the app fixes it. SoundGuys measured the Bass Reducer preset and found it “creates a sound more aligned with our headphone preference curve.” TechRadar, Reviewed and headphonecheck all say the HearID hearing test is what makes it sound good. Against that, Trusted Reviews lists “EQ options are rubbish” as a con, RecordingNOW found the custom EQ made little difference, and Head-Fi's reviewer, who measured his way to a correction, lists “Sound difficult to EQ to neutral” as the one con. One outlier hears no V at all: Trusted Reviews says “these headphones sound flat out of the box,” which both rigs contradict and which fits a broken seal (see bass).
“These aren’t designed for critical listening but offer an exciting sound that most casual listeners will enjoy.”

“The sound quality is so disappointing that it is unlikely to please even casual listeners”
