Overview

The beyerdynamic DT 1990 PRO MKII is the second generation of the acclaimed DT 1990 PRO studio headphone. Launched in late 2024, this premium open-back model introduces the TESLA.45 driver and a reduced nominal impedance (30 Ω), targeting critical production work—mixing, mastering, and detailed editing—while maintaining German build quality [4].

Scientific Validity

\[\Large \text{0.8}\]

Independent, standardized testing reports excellent measured performance. On RTINGS’ Test Bench 2.0, the MKII shows very low harmonic distortion with tight stereo matching and group delay below audibility across the band; its mid-range tracks the target closely, though treble fluctuations can alternate perceived articulation and brightness [2]. The manufacturer specifies 30 Ω nominal impedance and provides two earpad sets optimized for producing and for mixing/mastering, supporting practical workflow choices [4].

Technology Level

\[\Large \text{0.8}\]

TESLA.45 is a ground-up 45 mm dynamic driver revision focused on efficiency (30 Ω), reduced distortion, and improved transient behavior. The package includes two pad sets (“Producing Velours” and “Mixing & Mastering Velours”), straight and coiled cables, and a hard case; parts are serviceable and assembly is in Germany [4].

Cost-Performance

\[\Large \text{0.6}\]

Value baseline (equal-or-better in function & measured performance): Sennheiser HD 490 PRO — USD 399 (B&H) [5]. On the same RTINGS bench, the HD 490 PRO deliver low distortion at both 94 and 104 dB SPL, group delay below audibility, and fewer treble fluctuations than the MKII while targeting the same open-back studio use and also including two pad sets [1][2].
DT 1990 PRO MKII street price (new): USD 699.99 (beyerdynamic official) [3].
CP ratio: 399 / 699.99 = 0.57 → score 0.6.

Reliability & Support

\[\Large \text{0.7}\]

Metal yokes, replaceable pads/cables, and robust construction support long service life; a hard case is included and service parts are available through the brand’s network [4].

Rationality of Design Philosophy

\[\Large \text{0.8}\]

Changes prioritize measurable performance (distortion, matching, transient behavior) and practical studio ergonomics (lower impedance, two pad sets), aligning with professional requirements [2][4].

Advice

If you prefer beyerdynamic’s build/fit and want low distortion with excellent matching, the MKII is easy to recommend [2][4]. If your priority is measured transparency per dollar, HD 490 PRO at USD 399 sets a strong value bar with equal-or-better lab results in several key metrics [1].
