Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Measured frequency response (dB relative) against the SoundGuys Headphone Preference Curve. When the measurement goes above the dashed line, that frequency is louder than our preference curve, and when it goes below: it's quieter. Use the curve for comparison purposes only, as your taste may vary.

Multi-Dimensional Audio Quality Scores (1–5), modeled from the measured response. Higher is better across timbre, distortion, and immersiveness — add other models to see where this one lands.
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.
