I bought this SMS unit based on a Consumer Reports review that rated the active noise cancelling (ANC) as Excellent. But the ANC on this unit barely works. By contrast, I have a two-year-old Bose QuietComfort 15 headphone set that has nearly perfect noise cancelling. <br /><br />For this SMS unit, I made sure to follow the directions: I charged the unit until the light glowed green, then I turned on the ANC and verified that the light was glowing blue. I tested them and gave them to a co-worker to test as well. We both had the same verdict: Very little active noise cancelling. What a big disappointment.<br /><br />The ANC on this unit is about 20% as effective as that provided by my two-year-old Bose QuietComfort 15 headphones. It doesn't silence people talking within 10 feet at all; merely makes them about 20% less loud.
