[Elecraft] Bose noise canceling headphones

[Stephen Prior]

I bought some noise cancelling Sennheisers in Changi Airport a couple of
years ago, they were not as expensive as the Bose, but not far off.  They
did a fantastic job of cancelling the sorts of frequencies which are
troublesome in a jet; I found that I could turn my iPod right down and still
hear it.

However, in a domestic situation I find that although they do reduce
extraneous noise, they don't do a wonderful job of it and the background
hiss caused by the amplifier I find unsettling.  Such hiss would not have
been audible in a noisy environment such as a jet.  Now it might be that the
Bose are very very much better, but it might be worth trying to find out
before lashing out $$$'s!

Hope that helps
