AKG K72 Frequency Response (measured on a B&K 5128)

Click a line or a legend entry to highlight it. Click again to clear.Tap a legend entry to highlight its line. Tap again to clear.

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.

Click a line or a legend entry to highlight it. Click again to clear.Tap a legend entry to highlight its line. Tap again to clear.

Solid lines: passive isolation (dB) with ANC off — how much ambient noise the fit blocks on its own. Higher on the chart means more attenuation.

The verdict

AKG cuts too many corners with the AKG K72. They don't sound very good, and feel pretty cheap with stiff cushioning. That AKG retains the tension based headband and light clamp force are the main good points here.

✓Liked: Price, Lightweight, Comfortable headband

✕Could be better: Wonky sound quality, Mediocre isolation, Stiff padding

How we verify owners
