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.
