Audio-Technica ATH-M20x vs Superlux HD 681

The Superlux HD 681 are better headphones for neutral sound than the Audio-Technica ATH-M20x. The Superlux are semi-open headphones, helping them create an immersive and natural soundstage. They also have a more balanced sound profile, which some users will prefer. However, the build quality is pretty cheap and fragile. On the other hand, the Audio-Technica will be better if you're live recording since they're closed-backs, which means they block a bit of ambient noise and don't leak as much audio.
