Title: No active noise reduction AT ALL!
Review: I just brought these home from Staples. I cannot see how these can be claimed to have ACTIVE noise reduction. The only thing they do is slightly amplify the source sound. The classic test, to turn them on with some background noise but no signal, reveals ZERO noise reduction. There does not even appear to be a microphone anywhere in the system that could detect and correct for noise. Nothing you do with the battery unit (moving closer or further from noise sources, for example, indicates that ANYTHING is happening at all. The product is apparently falsely presented. The flexible plastic earbuds are reasonably good, and block sound almost as well as my KOSS Sparkplug earbuds, but there is NO evidence of any active noise cancelling at all. I plan to return them.
