Does anyone have any experience of the relative merits of active,

isolating earphones ?

I want to get a set to use with an MP3 player on trains and planes. At
the same time I would also like to be able to use them with a radio at
motor race meetings.

My requirement is to be able to listen at sensible ( low) volumes.
Decent sound quality would be a bonus, but the main requirement is
actually be able to hear music/commentary.

My inclination is to go for something like the Shure E3 or Senheiser
equivalents. But how well will they work on a plane. I can always
stick a pair of ear defenders over the top at Le Mans etc..

How good are the active devices?

The cancelling type only work up to about 500Hz BUT that's the most
energy-rich part anyway. I found the best compromise is to use ear plugs
(general, full range reduction) WITH cancelling headphones, turned up LOUD.
It might make your neighbour worry about your listening levels but you get
the best of both worlds!

Good luck
