The sound is absolutely better. Look at this diagram to understand how dramatically different the frequency's are affected compared to foam plugs:
ETY Plugs (normal 15db plugs:
This is how the MusicPRO electronic earplugs affect things:

Slowly? The stapedius reflex typically has an onset latency of between about 25 ms (for very loud sounds) and about 250 ms (for threshold-level sounds). The decay of the stapedius reflex can be as long as 5-10 seconds, but the onset is typically much less than a quarter of a second.

As I understand it, this is true through to 90-100db depending on the person. Response past that takes significantly longer, and is still not particularly effective. Which is where the idea of popping plugs out just in time to play comes in as a bad idea, especially if there will be burst of extreme sound from percussion, speakers, or trombones.
Don't get me wrong - I'm not saying that we should NOT wear earplugs in favor of "open hearing". My point is that we need to wear earplugs in any situation that goes above dangerous levels. Our ears have never really developed to stop noise beyond 100db anyway, which is why we should invest in hearing protection that can be worn consistently in any situation that goes above this level. |

According to the experimental results I've seen, the stapedius reflex has a substantially faster onset with a louder stimulus. But the amount of attenuation maxes out at about 20 dB, so it doesn't provide the level of protection that foam plugs provide.
Schlomo Silman's book on the subject is full of information.

+1! Still like Mack's Ultra Soft Foam Earplugs very comfortable "sit" in the ears |

Even modestly priced hearing aids cost $3000/pair and few insurance plans cover them. My hearing loss is due primarily to heredity but I sure wish I had used earplugs while mowing grass as a kid.

I'll second that. Lawn mowing and snow blowing took their toll on me. These days, I wear shooter's headphones when operating loud equipment -- and when playing the trumpet. |
