The verdict
Though they're quite large earbuds, the Technics EAH-AZ80 are very solid performers, with a rock-solid array of features to boot. Though the sound might not be for everyone, we believe most should really like these earbuds, even if they aren't the consensus best-ever.
✓Liked: Simple controls, Feature-laden, Battery life, ANC
✕Could be better: Price, Mass, Circular nozzle
