All of them, compared to over ear monitors. You can't out engineer physics advantages of a larger speaker. Airpods fall short of other in ear monitors too fwiw, so they are a poor choice in class.
Physics doesn't prevent reproduction of bass in IEMs. Thanks to inverse square scaling of sound pressure with distance, putting the driver within the ear canal greatly reduces the required output level to the point where even tiny drivers can handle it. Lots of IEMs can reproduce loud, deep bass with low distortion.
You of course miss the whole-body tactile vibration effect of loud bass played on speakers, but the sound itself is there.
