The fact these don?t have noise cancellation is evident, especially when the wife fires up the mixer in the background while gaming. After using it, I realized I didn?t need the extra size anyway. I continuously purchase Isotoner/IsoSpa slippers because they last. Only complaint is they are a tad too big, if these came in a solid 11 (instead of the half sizes) these would be perfect, but we figured the 10. I would say my charge time is cut down by at least 1/3 using this. I was going to purchase the cloud stingers cause I had them previously and they were so good. However, the microphone never worked. People with narrow feet may find the shoes to be too loose. It is entirely not that. My case is I usually wear an 8.
