You definitely have a point there. The 3DME uses small MEMS microphones embedded in the faceplate of the earphone and has no physical windscreen or noise suppression like digital hearing aids and consumer buds which use aggressive software algorithms to detect wind and instantly cut the low frequencies to stop the rumble.

As a workaround, some artists performing outside wear a thin, acoustically transparent beanie or headband over the ears effectively acting as a pop-filter/windscreen. This breaks the wind before it hits the mic while still letting mid-to-high frequency sound (speech/music) pass through. Not exactly a hearing aid alternative.
