Having tried both, I would go for the passive ear canal types that
double as ear plugs. I use Etymotic, but there are plenty around. They
are light and don't get in the way. On planes, if you fall asleep
wearing them they don't end up over your nose. Also the frequency
range over which the active types attenuate is rather limited.


Thanks Don,

I've got a pair of the E6i(s) on order..
