They are also soft inside. I needed to buy this cord for my 14 year old son who lost the original cord. The customer service of this seller, is second to none, thats for sure. The sound quality isnt great. Ive done hours of research, looking into the pros and cons of all kinds of sets from $5-$300 and what Ive learned is that there is no perfect set. Set up easy. Im 5"1 and 187lbs and ordered a XXXL. Battery life is remarkable. I did receive this item free in exchange for review however, all opinions are my own. I have some boots that I adore and they feel almost as soft as these slippers.
