Our Verdict
Superlux HD 681
Superlux HD 681 EVO
While the Superlux HD 681 and the Superlux HD 681 EVO are similarly performing headphones, the HD 681 are better for neutral sound. They have a more balanced sound and a more natural passive soundstage. However, the HD 681 EVO have slightly better build quality and are a bit more stable on your head.
