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
