Verdict: HD 800 S leads with a 56mm driver and 4 Hz-51 kHz response (per Sennheiser specs) versus DT 1990 Pro's 45mm and 5 Hz-40 kHz, creating a noticeably larger soundstage on RTINGS tests. DT 1990 Pro remains competitive for studio work with easier drive requirements and swappable pads. The 40 g weight difference favors the Sennheiser for extended listening per user feedback on forums.

The Focal Utopia uses beryllium dynamic drivers while the Sennheiser HD 800 S relies on ring-radiator transducers. Side-by-side reviews find the Utopia ahead in resolution and bass control.
The Beyerdynamic DT 1990 Pro uses 250-ohm drivers with a brighter treble peak while the Sennheiser HD 660S2 runs at 300 ohms with a warmer midrange tilt. Both open-back models target mixing use but the DT 1990 Pro edges out in detail retrieval per direct A/B tests.
