Our Verdict

Technics EAH-AZ80

Sennheiser MOMENTUM True Wireless 4

The Sennheiser MOMENTUM True Wireless 4 and the Technics EAH-AZ80 True Wireless are premium buds with premium feature sets. They both offer a comparable battery life performance and are similarly well-constructed. While both provide a great level of attenuation against ambient sound, the Sennheiser have the edge here, blocking out more external noise across the entire frequency range. That said, the Technics have a more comfortable fit and LDAC support, and they feature three-way Bluetooth multi-device connectivity for staying connected to multiple devices on the go.
