Score: 80/100
Bose QuietComfort Ultra Black
Score: 77/100Rankings
Technics EAH-AZ80-A offers dual-hybrid ANC, LDAC support and a lightweight 7 g design with three-device multipoint and wireless charging. However, ANC reduces playback to just 4.5 hours and the case lacks fast-charge speed. Suited for active users and multitaskers who value comfort and decent battery life.
The Bose QuietComfort Ultra (2nd Gen) earbuds offer class-leading ANC and AI-personalized sound with multipoint support. Battery life is limited, especially with spatial audio, and codec options are modest. Ideal for travelers and audiophiles who value ANC and fit customization.

Professional reviewers consider the EAH-AZ80 a strong contender for active-lifestyle users, praising its precise stereo balance, lightweight comfort, and robust ANC performance. The high-resolution audio capabilities and superior call quality further position it as a premium option for audiophiles and professionals who need reliable wireless connectivity across multiple devices.
Everyday users are enthusiastic about the immersive, rich sound and the clear calls even in windy conditions, appreciating the comfortable fit and the convenience of three-way multipoint switching. Recurring concerns focus on battery life under ANC, occasional Bluetooth hiccups when juggling multiple devices, and a bass-forward tuning that may not suit all listeners.
Professional reviewers consider the 2nd Gen QuietComfort Ultra earbuds a solid evolution of Bose's flagship wireless line, applauding the AI-driven CustomTune personalization and the class-leading ANC, while noting that the battery penalty of Immersive Audio and the modest codec selection keep the product from being a clear market leader.
The source material does not provide direct user reviews, but the emphasis on multiple eartip sizes, stability bands, and the Bose app suggests the design aims to address common consumer concerns about fit, comfort, and personalization.
