You are putting words and thoughts into the minds and mouths of others that are simply not there. I am weary to death of this utterly fruitless conversation but since you have mentioned me, I will respond this last time. As I have said, several times now during the course of this rambling thread, my main argument against wearing headphones while riding is a purely personal one in that I like to hear the sounds of the countryside around me. I enjoy the intimacy with the landscape that cycling brings me. I like to listen to nature - I can listen to music any old time home or in the gym, but I can hear the countryside like this only when I am cycling. I can't be any clearer than that, I shouldn't think. In terms of safety, yes - I believe one is far safer not wearing headphones while cycling.
Now, you have hearing difficulties - I get that. And nowhere have I - or indeed anyone on this thread that I am aware of - suggested that hearing impaired people should not ride. So climb down off your high horse or unicycle or whatever it is you're on. The point is, if you do not have to be hearing impaired on a bicycle, why do it? Hearing what is going on around you is very useful when you are on a bicycle - if you can, if you have that ability, it makes sense to use it.
But let me repeat - yet again - my primary reason for not wearing headphones and that is to enjoy the sounds of the countryside around me. Are we clear?
