#98 Sennheiser HD 490 Pro: $391.75 Amazon eBay
Pros: Across 12 hobbyist measurements on squig.link it earns a preference score of 75.1 with a smooth 2.0 dB spread around the target, so nothing in the response jumps out as harsh or hollow. Bass sits about 2.6 dB above target between 60 and 200 Hz and stays within 6 dB of target all the way to 20 Hz, giving a full, warm low end that suits listeners who like weight under their music. The open back and 260 g weight make it a light option for long sessions at a desk.
Cons: Low mids run about 2.3 dB hot while the upper mids sit 1.7 dB low, which thickens vocals and guitars and pushes them slightly behind the bass. A 4.5 dB dip near 9.2 kHz dulls cymbal shimmer, and the open back leaks sound and blocks no outside noise. The Austrian Audio Hi-X65 rates higher for less money, and the Audio-Technica ATH-M60x and Sennheiser HD 620S match its rating at a lower price.
