Short answer: the Audio-Technica ATH-MSR7b. It ranks #129 of 481 over-ear headphones by sound quality, rated 3.9/5, at $249; the Sennheiser HD 620S ranks #203, rated 3.7/5, and costs $251.44, so there is little reason to consider the other one.
The case for the Audio-Technica ATH-MSR7b: A preference score of 80 in oratory1990’s measurement, with bass close to target from 60 to 200 Hz for punchy, even low end. The catch: Presence sits about 3.1 dB below target from 3 to 6 kHz and an 8.8 dB dip near 9.5 kHz takes the bite out of guitars and the shimmer off cymbals.
What the Sennheiser HD 620S does well: Bass from 60 to 200 Hz is lifted about 2.6 dB while sub-bass sits within half a dB of target, giving a punchy, well extended low end. The tradeoff: At 150 ohms and 110 dB SPL/V it is more demanding than most headphones here and benefits from a headphone amp rather than a phone.
Buy the Audio-Technica ATH-MSR7b. It is rated higher for sound quality than the Sennheiser HD 620S and costs less, so only choose the other one for a particular feature it does better.
