Who says closed-back headphones can’t sound that open? The closed-back HD 620S is for audio enthusiasts seeking a distraction-free listening experience without compromising on natural, airy and detailed sound. Featuring a remarkably open baffle and angled transducers, it replicates the spatial imaging of loudspeakers while keeping listening sessions secluded.
Enjoy undisturbed privacy while listening to exceptional open, natural sound.
Open sound in a closed-back design.
No matter whether all day, all week or all year.
Your passion knows no boundaries. Why should your headphones?
How to read frequency response measurements for headphones: The frequency is shown in Hertz (Hz) on the X-axis (numbers at the bottom). The bass response is from 20-300 Hz, the vocal range runs from 300 to 3000 Hz, and the treble is from 3000 to 20,000 Hz (i.e., details in the music). On the Y-axis (numbers on the left), the relative loudness is shown in dB SPL (decibel Sound Pressure Level). The higher the graph line, the louder the frequency. As an example: The bass response between 20 to 100 Hz is much louder in the HD 620S (white line), compared to the HD 600 (grey line). The frequency response is supposed to be perfectly flat in loudspeakers (i.e., all parts of the music are equally loud), but ear geometry and psychoacoustics mean a good headphone frequency response looks very different. While the science is not yet settled, most engineers and scientists in the headphone industry would agree that the HD 600 with additional bass is closer to a neutral, “true-to-life” sound.
