Most sources land on “neutral with a bright tilt” — flat-to-warm through the bass and mids, then the Beyer treble. The lab-minded sources call the shape studio-correct below 5 kHz and wonky above it; the sceptics say it still needs EQ before it is honest. The stock Producing pads add roughly 3 dB of bass and low-mid warmth over the Mixing pads, which is the only tone control you get.
“The overall sound signature of the DT 1990 PRO mkII could be called ‘neutral’ when using the (stock mounted) ‘producer pads’.”
DIY-Audio-Heaven (solderdude)
“the beyerdynamic open‑backed model has a gently ‘scooped’ tonality in comparison, with a broad treble boost starting around 5kHz and extending well above 10kHz complemented by a slight bump in the ‘upper bass’ region”
Sound On Sound (Sam Inglis)
“The DT 1990 Pro MkIIs are bright, lively headphones with a boost in the treble, a smaller boost in the bass, and an overall huge sound.”
SoundStage! Solo (Geoffrey Morrison)
“Highs are somewhat wonky and quite a ways off of both our Headphone Preference curve and Studio Curve.”

Measured
RTINGS files it as a flat sound signature (bass −2 dB, treble −1 dB against its target). On the GadgetryTech data, compensated to Harman 2018 and normalised at 500 Hz, the Producing pads sit within about 3 dB of target from 100 Hz to 6 kHz, then +8.6 dB at 8 kHz. DIY-Audio-Heaven adds the catch of a 30 Ω driver: on a 120 Ω headphone output the balance shifts noticeably toward the bass and low mids, which the 250 Ω original never did.
