Score: 78/100
Nothing Ear (a) White
Score: 86/100Rankings

The Nothing Ear (a) in white offers the same transparent design, hybrid ANC and long battery life as the black version, but shares the same compromises in sound balance and lack of wireless charging.

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.
