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.

Soundcore Sleep A30 Attenuation (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.
Solid lines: passive isolation (dB) with ANC off — how much ambient noise the fit blocks on its own. Dashed lines: total attenuation (dB) with ANC on — passive isolation plus active noise cancelling. Higher on the chart means more attenuation.

The verdict
The Sleep A30's ANC improves upon the A20's biggest weakness, making these notably better at blocking low-frequency sleep disruptions. However, at $229 retail, the price is a bit too steep.
✓Liked: ANC, Sleep features, Comfort
✕Could be better: Battery life, Unresponsive touch controls
