Technics EAH-AZ40
Score: 80/100
Sony WF-C500 Black
Score: 75/100Rankings
Technics EAH-AZ40-S combines LDAC hi-res sound, 10-hour ANC playback and a 28-hour total battery with three-device multipoint and app-based EQ customization. Its feed-forward ANC is less effective and LDAC cannot be used while multipoint is active. Great for multitaskers and commuters needing long battery life.
The Sony WF-C500 deliver balanced sound with up to 20 hours of total battery life and customizable EQ via the Sony Headphones Connect app. They lack active noise cancellation and have physical button controls that can be inconsistent. Great for value-seeking users who prioritize neutral audio and long runtime.
