Bought these for my spouse because hes in the military and needs a black pair and his current ones thebesr piece is falling off. Got them in an Amazon flash deal $10 so was like sure what could go wrong. Well we cant wear them because the SMELL HORRIBLE!! I put the in a plastic baggy with carbon sachets to see if it helps...almost a week later and it doesnt appear to be doing anything and we might be returning them because the smell is unbearable and they are on ur nose...uh nty!
