What reviewers said
Sony WF-1000XM6
The Sony WF-1000XM6 true wireless earbuds deliver a top-tier audio experience with adaptive noise cancellation and robust sound quality, making them a strong all-around choice for daily use and workouts. They feature a long battery life, LDAC support, and multipoint connectivity, though their premium price and slightly bulky case are minor trade-offs. Overall, they excel in most areas, with call clarity and customization options further boosting their appeal.

- Pro:Rich, detailed sound with LDAC support
- Pro:Long battery life even with ANC on
- Con:Premium price point may deter budget buyers

Technics EAH-AZ40M2
The Technics EAH-AZ40M2 are a well-rounded pair of true wireless earbuds that offer a spacious soundstage, a solid feature set, and a sleek design for their price. They perform competently in most areas, though they lack the aggressive punch and drive of some rivals, and their noise cancelling and overall sound don't quite reach the top tier of their class. They're a stylish, comfortable option for midrange buyers, but they face stiff competition from more dynamic models.
- Pro:Spacious and open soundstage
- Pro:Attractive, compact design with comfortable fit
- Pro:Strong feature set including LDAC, multipoint, and quick charge
- Con:Lacks punch and drive in the bass
- Con:Noise cancelling is competent but not class-leading
- Con:Sound quality doesn't stand out against top competitors
