What Ive noticed about this compared to other safety ear muffs is that I can actually hear the music and podcasts. Several problems with this product. Once I plugged these muffs in, they transported me to another galaxy of wonder and bliss. Also, because the foam has flattened out the fit of the slipper has drastically changed and no longer fits your feet snuggly. Great sound quality, battery life decent. They can be worn outside for minimal trips--to the mailbox, etc. Even phone calls, which are not important to me, work great with these. I am PROBABLY not likely to return these. FOLLOW UP AFTER A FEW DAYS OF USING:Ive dropped my review down to 3 Stars. They are super comfortable, fit perfectly and are really cute!
