Our Verdict

Sennheiser HD 490 PRO

Sennheiser HD 620S

The Sennheiser HD 490 PRO are open-back headphones with a more immersive sound than the closed-back Sennheiser HD 620S. The HD 490 PRO supply a much more consistent sound. They also include an extra set of ear pads and perform better than the HD 620S for people who wear glasses. The HD 620S are well-made and comfortable with a sparser set of accessories. Their noise isolation makes them more suitable to wear in different environments. Sadly, their bass response is highly impacted by their inconsistent frequency response, but if they fit you well, they add extra punch to the bass compared to the analytically tuned HD 490 PRO.
