In praise of... noise cancelling headphones

I've just come back from a trip to Europe involving two 24 hour plus air flights from and back to New Zealand. I recently treated myself to a pair of Bose QuietComfort 20i Acoustic Noise Cancelling Headphones. I don't usually promote products on this blog but I have to say I can't praise these headphones highly enough. Bose came up with the idea for noise cancelling headphones and they are issued to pilots and as standard in business class on many airlines. I would recommend that if you fly often you must invest in a pair. I finished each 24 hour flight (yes New Zealand is a long way from the rest of the world) feeling much more relaxed because I never heard that constant engine roar. I just heard the movies, my music or near silence. I really believe I left each flight much more rested than previously. Highly recommended.
