Imagen © TechnicsTechnics EAH-AZ40 true wireless earbuds deliver high-fidelity sound with 6mm drivers, JustMyVoice technology for clear calls, and IPX4 water resistance. They offer up to 7.5 hours of playback per charge and 25 hours with the charging case.
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.
