Noise Cancelling Headphones

Bought an Iriver on the weekend. 20gig MP3 player, like an Ipod with more bling.

Has anyone had any experience with noise cancelling headphones? Found a set at JB for $99, ear plugs with the rubber seal bit.

Not sure how they would go under a helmet and whether they are worth the extra dough.

i did a group buy of some sony ones a couple of months back.
i find them really good, but i dont use em that often as my commute is only a couple of minutes long. I have used them on some long rides etc and once you get used to em they are great.

Haven't used em but I know you can get pilot headsets that use the same technology.

I use my sony ones every day (thanks Ment) and I love them, never had a problem or been uncomfortable

i was eyeing them off too at bing lee. the only stopping factor was the pricetag, was a touch offputting.

do urself a favour and get urself some koss earbuds.
the outter part is like an earplug, u squish them in then put em in ur ear and they expand to fit ur ear hole. I'm guessing this is the style u mean.
Koss are the best quality by far.
Always had 'em never had a prob.
