Etymotic in-ear headphones (and probably all ear-buds) don't have noise cancelling per se, but do supress the external noise levels by virtue of their design. And they apparently do it very well. I use Bose noise cancelling headphones on the 'plane with a CDP and a Total Airhead.
For your second application, why do you want wireless? You won't get really high performance if you require wireless.
Are these also going to connect to your iPod, or are you planning to run these from your main system?
