My left ankle, which was the worst, hardly swells at all. Removing those is simple, just twist them and gently pop them off. The only time consuming operation was running the electric cords through the base interior and that went smooth. Other than that, a great addition to our travel kit. (Seems like this should be a standard feature, as its so nice)CONS-Poor ANC-Weird open mic mode that doesnt work that well-Soft carrying case-Sometimes sound doesnt pause when taken off the ears or play when put back on (probably a sensor problem)-When I am on a call, my partner hears outside voices louder than my own (the mic isnt well directed clearly)Ill edit this as I notice things! recipient was delighted with this toy! So you pay money for an extended warranty on an item. So, I decided to order a kiddy size 6 as I only needed something to wear around the house. I am so happy I went with this type. And I am so glad I bought this!
