Title: Effective NR, good sound, low price.
Review: It appears most of the reviewers who found the noise reduction ineffective were testing it out in normal listening environments such as a home or office. The NR will not be noticable for this use, as it primarily works on the low frequencies. All you will hear when activating the electronics is a slight increase in volume & associated hiss. I also thought the NR wasnt working, so I took my mp3 player to a laundromat and put them to a test. The NR worked very well in reducing the low frequency washer & dryer rumble. The 70% figure seems about right, but only on the lows. I am a professional musician & recording engineer, and was very impressed by these phones. 5 stars, as they are a fraction of the cost of similar Bose units.
