I haven't played yet with an Ipod, I have thought about it but generally like to hear what is going on around me to some degree.
Flip side of the question though.
I have in the past played 8 and 9 ball while talking on my cell phone via wired ear piece and actually played very well. These were not serious calls, just chatting with family or friends. I wouldn't stop talking while shooting, my muscle memory would kick in and I could actually run out racks in either game. It's as if I wasn't thinking about the game but just shooting and shooting very well. A few people were bewildered by it because we talk so much about focus and preshot routines, etc. I was consistant in these area's, but it felt like talking on the phone actually got me into the zone faster.
I also think that when you actually don't hear your cue hit the cue ball when shooting, you are playing very well or close to the zone. It seems that if I don't hear the hit, it's a sign of my stroke being dead on and my stroke and mind working as one.
