I recently bought the Sennheiser PXC 450 NoiseGard Active Noise-Canceling Headphones. I was intrigued by a TED lecture on the effects of noise on our lives physiologically, psychologically, cognitively, and behaviorally. I work in a sea of cubicles next to someone who has incessant distracting conversations at inappropriately loud decibel levels. I also fly a fair amount, not a much as a consultant, but probably a couple standard deviations above the norm. So for both of these reasons I thought I might benefit from some noise canceling headphones. My brother had purchased the same headphones and seemed to be happy with his purchase.
Overall, I am very happy with the sound quality of the headphones. The noise canceling seems to be effective as well, when my furnace, which is quite loud, kicks on it is barely noticeable with the headphone on using active noise canceling. I have not had a chance to test the headphone on an airplane flight yet. I will update the post the next time I take a flight, which will be in a couple weeks for Thanksgiving.
I recently took a trip to visit a friend in St. Louis for Thanksgiving which afforded me the opportunity to put the noise canceling headphones to the test. I was very impressed at the ability of the headphones to cut out the ambient cabin noise, it made for a much more pleasant and less stressful travel experience.
