Our Verdict
Beyerdynamic DT 770 PRO
Sennheiser HD 820
The Sennheiser HD 820 are slightly better closed-back critical listening headphones than the Beyerdynamic DT 770 PRO, but not by much, especially considering the price difference. The Sennheiser have a much better and more premium build quality. They also have more spacious and well-padded ear cups that are breathable enough to wear for much longer than the Beyerdynamic. They come with more high-end cables and accessories and don't sound as sharp on vocals and instrumentals as the Beyerdynamic. On the other hand, the Beyerdynamic offer a better value for their price with a more consistent bass reproduction and a fairly even and neutral mid-range. They're also decently well-built and comfortable enough for most, although they can be tight on the head for some.
