Comments about Audio-Technica Audio-Technica ATH-ANC25 QuietPoint Active Noise-Cancelling On-Ear Headphones:

I was planning to use it when traveling by trains and flights. But after my first travel, I am disappointed and will not likely use it any more. [...] I can not find a way to use it.It does cancel some surrounding noise, but far from it claimed 80%. I guess it might be around 40% for some kinds of noise. The remaining sounds still can drive me crazy. It seems does not cancel plane's engine noise, and those sounds from subway. I have a pair of ear-buds with me, and it turned out I used the ear-buds almost in the whole travel.I have never used other high end echo-cancellation headphone, so can not compare. But for travel, a pair of ear-buds should be enough.
