Our Verdict
Sennheiser HD 820
Focal Stellia
The Focal Stellia are slightly better headphones than the Sennheiser HD 820. The Focal are better-built and feel like more premium headphones. The Sennheiser are mostly made of plastic and, although they feel durable, they don’t feel quite as luxurious as the metal and leather build of the Focal. Both headphones perform reasonably similar sound-wise, but the Sennheiser sound a bit boxier. They’re similar headphones otherwise, so your decision will mostly come down to preference.
