Netty,
It all depends on how far you push those ear plugs in.
Once I had them in like I would at the range, I could hear the music just fine, wife called at 75mph no problem, but when the highway patrol was yelling at me over his PA I had no idea what he was saying over the music, pipe an ear plugs.
I have found the sweet spot now and have no probs, see it was just cuting down the wind is what I was looking for, the volume of everthing was fine.
So yes!
