Title: Not the noise reduction you are looking for
Review: These headphones were a bad decision on my part. They advertise Noise Reduction, but I think the NR creates more noise than it attenuates. If there is any breeze or wind, you get this maddening low frequency sound. If there is no breeze or wind, the music is louder but I didn't notice any active noise reduction. With the noise reduction turned off, the headphones are decent, but a bit boomy for my tastes.
