Score: 78/100Rankings

The Technics EAH-AZ80-K provides high-resolution audio, effective dual-hybrid ANC, and a rich feature set including multipoint pairing and wireless charging. Its battery life and touch-control sensitivity are the main drawbacks for power users.

The Technics EAH-AZ40M2 offers audiophile-grade sound with LDAC support, effective dual-hybrid ANC, and seamless multipoint connectivity, all packaged in a lightweight, eco-friendly design. Battery life is modest, especially when using LDAC, and the case lacks a charge indicator.
