There is no real tech in those plugs. There rely on what is called non-linear filtering. You get just the same effect with a very small stepped vent. Lower intensity sounds are let through with minimal attenuation but high intensity peaks are significantly reduced.

They can never be a patch on electronic plugs for hearing soft sounds.
