Personal Review
"The Sennheiser HD 820 is exceptionally comfortable and lightweight, with a fantastic sound experience. However, with a significant price tag, the headphones' durability issues involving cable failures make them less appealing for some users. While offering some premium features, these headphones may not be the best choice for value-seeking audiophiles."
— Maxim Assaraf
8.5
The Sennheiser HD 820 has a great bass response. It's fuller in the low/mid-low end, resulting in a satisfying thump. Although it's more prominent compared to open-back headphones like HD800s, it copes exceptionally well, giving a pleasing bass output.
8.5
The HD 820 delivers incredible treble detail. The treble highs are sharp and crisp, never coming across as dull or muddy. This ensures an overall vibrant and enthralling auditory experience while avoiding intrusive and harsh 's' or 'sh' sounds.
7.8
The midrange and vocals are pronounced, with a rich and vibrant resonance. It doesn't beat the open-back Sennheiser HD800s in terms of midrange clarity, as they have a slight edge yielding an overall smooth, refined and natural renditions.
