The verdict

AKG cuts too many corners with the AKG K72. They don't sound very good, and feel pretty cheap with stiff cushioning. That AKG retains the tension based headband and light clamp force are the main good points here.

✓Liked: Price, Lightweight, Comfortable headband

✕Could be better: Wonky sound quality, Mediocre isolation, Stiff padding
