I usually ride with an mp3 player. I find that the reduction in situational awareness is ok for me. The time I was run over I didn't have music on. I try to ride defensively, with assertive positioning and many rear checks and much anticipation of idiocy.
FWIW I have non-marshmallow type earbuds, and I have the volume at a reasonable level. On busy roads and when windy the traffic or wind mostly drowns out the music.
I find I can easily hear emergency sirens long before the vehicle is visible, I need to take avoiding action, or I could hear it if I were in a car. As a comparison I find the ocerall effect is much less than when listening to the radio in the car at a normal volume. (And much less than the boyracer volume I used to use in my younger days!). Occasionally things surprise me from behind (where are you Fnar?) but I've not found this a problem, as I tend to have checked rearward if there is a hazard, and also happens when I don't have music on.
I think it can depend on the person, and their personal assessment of the risk, based on their own behaviour, If you plug yourself in and blunder about oblivious to your surroundings, then that is likely to be dangerous, but if you are cautious, sensible and copmpensationary, then it can be an enhancement of the experience.
as we know, some pedestrians will step out blithely when the iPod is on, others (such as myself) will make careful visual checks before leaving the pavement, aware they may not hear bicycles or quiet traffic.
