What reviewers said
Technics EAH-AZ40
The Technics EAH-AZ40 earbuds deliver accurate audio and solid call quality in a lightweight, comfortable design, with useful extras like Bluetooth 5.2 and multipoint pairing. However, they lack active noise cancellation, wear detection, and advanced codecs, and their bass-heavy tuning can falter on complex rhythmic tracks. Overall, they are capable everyday buds that stop short of being top-tier due to missing premium features.
- Pro:Accurate, detailed sound signature
- Pro:Reliable multipoint connection via Bluetooth 5.2
- Pro:Lightweight and comfortable for extended wear
- Con:No active noise cancellation or wear sensors
- Con:Only SBC/AAC codecs, no aptX or LDAC
- Con:Bass can overpower rhythm in busy tracks
Technics EAH-AZ80
The Technics EAH-AZ80 are premium true wireless earbuds that deliver detailed, high-fidelity audio with support for LDAC, along with effective active noise cancellation and seamless multipoint pairing for up to three devices. They offer a comfortable, secure fit, a solid battery life of 7.5 hours per charge (24 hours with the case), and useful extras like wear detection and a quick-charge feature. While the sound quality and build are impressive, the price point is steep and the touch controls can be finicky for some users.
- Pro:Excellent sound quality with LDAC support
- Pro:Strong active noise cancellation
- Pro:Multipoint connects to three devices at once
- Con:Premium price tag
- Con:Battery life is average for the class
- Con:Touch controls may require adjustment
