Measurements:
What does that mean?
The dashed black line represents the Harman target, a reference frequency response developed based on consumer preferences. The red/blue line represents the measurement of the HD620S. In practice, it shows how much the headphone's frequency response deviates from the target. However, note that the target is highly smoothed, and it is not necessary to strictly adhere to the Harman target for a headphone to sound good.
This one has a strong emphasis on the bass around 100Hz, and again some emphasis on the lower mids. This means it will not sound shrill, but make the body of the music stand out more instead. This will sacrifice a bit of resolution and timbre for a fun listening experience.
