I have a pair of noise cancelling headphones which I love very much. Putting them on during a long haul flight and keeping them on most of the time leaves me significantly less tense and more relaxed when I hit the ground. They are the over-the-ear type which cost ~$200, and they are truly worth the investment. The problem is...
When I travel for pleasure I like to travel light, typically only bringing a 35L backpack. I usually bring a pair of earbud headphones, but they don't work nearly as well. My questions are
Has anyone seen a good comparison of the in-ear noise cancelling headphones versus the over-the ear type? Personal experience is ok, but I would be more interested in a comparison which includes some plots.
I've been looking at non-headphone earplugs like the LiveMusic, Etymotic Research, and EarPeace HD. These are made for musicians so I expect that they are effective at some frequencies, but I don't know how well the work for the low frequencies associated with flying. Has anyone seen a comparison of these to noise-cancelling headphones? Has anyone tried them out?
Does anyone have any other recommendations for quieting the deafening roar of flying?
