They can be worn while holding a conversation with the FA or a seat partner.

As an owner of the Bose QC2s (and having used canalphones in the past), I'd agree with the above with the caveat that they don't really
add hiss . . . they just don't attenuate it as much as the lower frequencies. Eliminating higher frequency background noise with noise cancellation technology is nearly impossible outside of a carefully controlled environment.
The actual attenuation at the lower frequencies is more like 15-17dB.
I'm one of those that find canalphones uncomfortable, and dislike having to remove them to talk to a seat-mate or FA. Getting them reseated properly and quickly takes practice, too.
