How we test ›Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Anker Soundcore P40iSoundGuys Headphone Preference Curve
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.

The verdict
The P40i work well enough for casual listening if you can tolerate their boomy bass and loose fit. The built-in phone stand is handy but the sluggish controls and poor call quality make them feel cheap in daily use despite decent battery life and noise cancellation.
