At 5.6, its noise isolation / ANC beats 47% of wireless earbuds we've measured.
Measured on 133 of the 271 we've cataloged.
A 4.8 puts its audio quality in the top half of wireless earbuds we've measured.
Measured on 64 of the 271 we've cataloged.
wireless earbuds — based on 245 of 271 we've cataloged.
IPX5 appears on 12% of the 244 wireless earbuds we've cataloged (of 271).
Active is the most common — on 61% of the 172 wireless earbuds we've cataloged (of 271).
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.
Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Measured frequency response (dB) against the SoundGuys house target — the dashed curve. The closer the measured line tracks the target, the more neutral the tuning; peaks ride above the target, dips fall below it.
